BUG 2001.06.10.001
Status: FIXED
The Navigator does not add scrollbars to a single page that is too large to fit into the content area.
Details:
When pages are loaded directly into the content area of the Navigator, not via the pagebrowser system, the Navigator does not add scrollbars so thata part of the page is not readable. This is of concern to the Edmonton people who have content that does not use the pagebrowser, and there may be other users of CANU as well who want to use CANU for all kinds of purposes without the pagebrowser and who will need these scrollbars.

BUG 2001.07.04.002
Status: FIXED
This may be a problem with the Arranger, but one notices it in the Navigator. The problem is that Get Information items do not show up in the Navigator with questions that have been entered as Question items.
Details:
For example look at Vectors/Scalar Multiplication/Test Yourself/Question 1. This item should have the Get Information items "Vector" and "Scalar Multiplication".

The Concept Table should be added to the Location Tracker as an optional navigation mode. The Concept Table would be removed from the Search dialog. The student will be able to choose between "concept map" (the current mode), or "concept tree" mode for navigation of course content.
Details: It is desirable to have a more compact and efficient navigation scheme for the CANU Arranger. The Concept Table will be provided as an alternative to the Concept Map style of navigation. An extra button (or menu) will be added to the Arranger to allow choice of the navigation scheme to use.

BUG 2001.08.04.001 STATUS: FIXED
Question items don't work, not even the multiple-choice items.
url: Vectors/Addition/Test Yourself/Basic Addition 1
The edit panel in the Arranger does not show the URL under Question Location and does not show the URL's of the response pages. None of it was copied over from the existing PIECES. Also, the related Topics and the Get Information items were not copied. The item appears in grey on the Navigator.

BUG 2001.08.09.001 STATUS: OPEN The concept map in the Navigator does not have scroll bars when the window gets resized. As a result some concepts may become invisible.
url: MAP
After downloading a course and displaying some concepts on the right, somebody may decide to shrink the screen horizontally. CANU does not insert horizontal scroll bars and the concepts that are displayed do not get wrapped around. They stay in fixed positions, and can become invisible if the screen size is reduced too much.
I am not concerned about this one for the purposes of MAP, but maybe there are some other applications of CANU where this could be troublesome. Usually, though, I would expect people to want to enlarge the window, not decrease it.

BUG 2001.06.10.003
Status: FIXED
Question items don't get copied fully.
Details:
When one uses the Arranger to copy a multiple-choice question item
from one part of a course to another, or from one course to another, not all choices get copied over and the copied question is useless. Also, the navigation system at the bottom of the question takes you back to the directory, not to a response page.

BUG 2001.06.11.004
Status: OPEN
The content table in the Arranger often has vertical and horizontal green lines missing.
Details:
Some of the vertical and horizontal green lines linking subconcepts in the Concept Table of the Arranger are sometimes only partly drawn. This seems to occur randomly and sometimes not at all. It does not affect the functionality of the Arranger. The lines get drawn in when one clicks on the relevant item or +/- sign.
This happens both in the concept table that one sees when opening the course and in the concept table that one gets in the pop-up window when one edits an instruction item.

This bug will be eliminated when the Concept Table is moved from the search dialog to the Location Tracker as a navigation option.
BUG 2001.06.13.005
Status: FIXED
If one opens two copies of the same course in the Arranger, one of them will be read-only. Nevertheless, one can delete items from the read-only course.
Details:
If one deletes an item from the read-only course, it is removed from the content tree. However, when one clicks SAVE, the Course Not Saved information does not disappear. So, presumably, the delete did not get saved. However, one does worry. The system should not allow removal of an item in the read-only mode, i.e., visually the concept tree should not get changed when one clicks on the X or tries to delete from the menu. Even better, the X and the Delete item in the menu should be dimmed when the read-only course is selected.
I did not try this with a read-only course that was different from the other course that was open or with simply a read-only course when no other course was open. Probably the bug will appear in these cases as well and should be cured as suggested.

Please add a copy-and-paste facility to the edit panels of the Arranger.
Details:
E.g., when entering the URL's of question choices in constructing a Question item, it would be very useful to be able to copy and paste the URL's for the distractors (and then have to change only a single letter per item). It is easy to make mistakes if these URL's are lengthy, and tedious anyway. People will find it "backward", I think, if they can't copy and paste words.

Copy and paste can be achieved ( through ctrl-c, ctrl-v ) if the correct permissions are allowed in the client java.policy security file; specifically the line
java.awt.AWTPermission "accessClipboard", "read, write";
must be added to the list of permissions.
BUG/RFE 2001.07.11.008
Status: FIXED
The Question Editor of the Arranger, in the case of numerical entry, needs an 'else' option.
Details:
The typical numerical entry question will require that the user gets a 'correct' response or an 'incorrect' response. The 'correct' response is triggered when the answer lies in the specified range. The 'incorrect' response should be triggered automatically when the answer lies outside of this range. It should not be necessary for the instructor to specify the range that will trigger the 'incorrect' response. (This would have to be a 'double' range with one interval below the correct interval and one above it, which would be tedious.)
In addition, the system should provide the possibility to catch certain incorrect answers for which one wants to give special responses. The system is capable of that at present.
I suggest there be an entry field in the Arranger labeled 'correct answer' and another one labeled 'incorrect answer'. The 'correct answer' field would let you specify the numerical range as at present and the URL. The 'incorrect answer' field would let you specify only a URL. In addition, there should be the present pull-down menu that lets you open 1, 2, 3, or 4 more fields that allow you to specify a range and a URL. These extra fields might be labeled 'specific incorrect answers'.
There would be no ticky-boxes accompanying any of the answer fields, correct or incorrect, because it is clear from the labeling provided by the system what the status of each is.
To see an example of how complicated things can get with the present Question Editor, look at Vectors/Addition/Test Yourself/Resultant Angle. In this example, there is a correct range, one incorrect range below the correct range, one incorrect range above the correct range up to a specific incorrect range, then the specific incorrect range, then the incorrect range above the specific range. Things work this way, but it is a pain to enter things this way.

BUG 2001.07.11.009
Status: FIXED
In the Question Editor of the Arranger, one can specify the numerical format. However, this format is not what is displayed in the Navigator.
Details:
The Navigator seems to request numerical input in the form 0.00E0 no matter what input is specified in the Question Editor of the Arranger. For example, see the Question Vectors/Addition/Test Yourself/Resultant Angle. In the Question Editor, the numerical format is specified as +000.0. It would be very desirable not to have to use the exponential format in many cases.

BUG 2001.07.12.010
Status: NOT A BUG
When one copies an instruction item from one part of a course into another part of the same course, the Get Information items don't get copied. However, the Related Topics do get copied. Related Topics attached to a Concept Item get copied as well.
Details:
When copying an Instruction Item from one part of a course to another, one may not always want to keep all Get Information or Related Topics items, because the Instruction Item may serve a different purpose in the new location. Thus, in general, the Get Information and Related Topics items will have to be edited when moving an Instruction item. However, it is easier to delete a few of these than to add them. Therefore, I suggest that all of these items should be copied when copying an Instruction item.
(2001.07.12) Hans Laue
(2001.07.17) Graeme Irwin
This behaviour of eliminating "foreign" Get Information item references within a copied subtree is an intentional feature of the system. However, it is desirable to maintain these "foreign" references if the subtree is pasted back into a tree which contains the foreign items referenced. This should be attended to eventually.

There is still the old MAP icon on the top left corner when one opens a course in the Instructor. If anything, this should be a CANU icon. For the time being, I suggest to delete the icon. Having just the course name there will look good, I think.
Details:
(2001.07.08) Graeme Irwin)
It is not trivial to eliminate the icon all together. If an icon is not specified, the default Java L&F icon is used. I suggest we keep using the "MAP" icon until a suitable canu icon is created.

url: Vectors/Addition/Test Yourself/Resultant Angle
Details:
E.g., in the Angle question I wanted the correct answer to be -63.7 degrees, but could not enter the minus sign. I ended up rewording the question so that the answer now is 296 degrees. That way I lose a decimal. I should really have 296.3 degrees. (The latter does not matter, but it must be possible to enter minus signs.)

RFE 2001.09.10.001 STATUS: OPEN Make the interface clearer for entering error margins in the numerical answer question editor.
Details:
In entering error margins, one has a choice between 'None', 'Relative', and 'Bounded'. At first I just typed values into 'Bounded' and did not realize I had to check the related radio button. When testing in the Navigator, the question performed incorrectly.
I suggest the following interface. The default is to have the None radio button checked and the other two data entry field radio buttons unchecked. If somebody types into either 'Relative' or 'Bounded', the button for that field gets checked automatically, and the other two radio butttons get unchecked automatically.
I also suggest that as soon as a correct value (or target value) is entered, that the lower and upper bounds under 'Bounded' be set equal to this correct value automatically. Then, if somebody should check the corresponding radio button, these two values are consistent. If somebody types in a lower bound and forgets to type the upper bound, again the bounds are consistent. If somebody types a lower bound that is larger than the correct value, or types an upper bound that is lower than the correct value, the system should beep and restore the previous (consistent) value in the slot when the user hits Enter.
Finally, I suggest to replace the label 'Bounded' by 'Absolute'.

When one copies a several-page instruction item from one course to another, the mode of the page navigator does not get copied (say, no restart button, no page counter) but reverts to the version that has every possibility checked. For example, have a look at Acceleration/Instantaneous/Simulate It and copy it from PIECES to another course. The page panel at the bottom looks different in the new course.

If one changes the editing priviledges for a course while working on the Instructor Tab, the changes don't get saved.
Details:
Changes in the editing priviledges only get saved when one works on the Courses Tab, although they system invites the user to make such changes also on the Instructor Tab. Once such changes have been saved on the Courses Tab, they are correctly displayed also on the Instructor Tab. Actually, one can change the editing priviledges on the Courses Tab and then save them on the Instructors Tab. The only thing one cannot do is make changes on the Instructors Tab and then save them, either on the Instructors or the Courses Tab.
