Known Issues

1. Fix for ILIAS crash in Test & Assessment when random questions have been deleted accidentally

In ILIAS random tests the questions are not added as a copy like in the other question types but as a simple reference. If a question used in a random test is deleted from it's original question pool, the question is missing in the random test then and could lead to unpredictable results and ILIAS crashes. This behaviour is suppressed from ILIAS 3.6.2 and the upcoming ILIAS 3.5.11 on by preventing the deletion of questions in ILIAS when the questions are used in a random test. If this accident of deleting a question already happened, you need this fix to deal with it. Unfortunately it is impossible to bring back the deleted question but the users can at least finish their tests without causing an ILIAS crash.

To fix this bug, make a backup copy of the file assessment/classes/class.ilObjTestGUI.php, then copy the attached file class.ilObjTestGUI.php into the assessment/classes/ directory.

2. Fix to prevent ILIAS crashes in Test & Assessment by deleting questions used in random tests

In ILIAS random tests the questions are not added as a copy like in the other question types but as a simple reference. If a question used in a random test is deleted from it's original question pool, the question is missing in the random test then and could lead to unpredictable results and ILIAS crashes. This behaviour is suppressed from ILIAS 3.6.2 and the upcoming ILIAS 3.5.11 on by preventing the deletion of questions in ILIAS when the questions are used in a random test. If you don't want to wait to add this security patch to your ILIAS system, please work through the following instructions.

To fix this bug, make a backup copy of the files assessment/classes/class.assQuestion.php, assessment/classes/class.ilObjQuestionPool.php, assessment/classes/class.ilObjQuestionPoolGUI.php, assessment/templates/default/tpl.il_as_qpl_confirm_delete_questions.html, lang/ilias_en.lang, lang/ilias_de.lang then copy the attached files class.assQuestion.php, class.ilObjQuestionPool.php, class.ilObjQuestionPoolGUI.php into the assessment/classes/ directory, the attached file tpl.il_as_qpl_confirm_delete_questions.html into the assessment/templates/default directory and the attached files ilias_en.lang and ilias_de.lang into the lang directory.

When you are finished, please log in into ILIAS, go to the Language Administration and press the Refresh Languages button.

Please note, that you should not apply this patch if you are running an installation which uses other languages than english or german. In this case you must wait until the official 3.5.11 release or insert and translate the following language entries in your favourite language files in the ILIAS lang directory:

assessment#:#qpl_delete_describe_undeleteable_questions#:#The following questions are in use in random tests. You cannot delete these questions:
assessment#:#qpl_delete_no_deleteable_questions#:#All questions you tried to delete are in use in a random test
