	1: Problem Using Support Activity - Error Message By: John Fitchett		09/01/09 11:17 PM	[ Reply \| Forward ]
I have created a sequence that uses the 'Support Activity', but when previewing the sequence, the support activity doesn't open. The pop-up window opens, but displays an error message as follows: Pop-up location url: lams/errorpages/error.jsp Sorry, there has been an error. There is a problem processing this request. Close the browser window and try again. If the problem persists please contact your system administrator or the technical forums on http://lamscommunity.org/. org.lamsfoundation.lams.learning.service.LearnerServiceException: Unable to set up url as session does not exist.

John, Any chance you can upload the sequence here so we can test it? Thanks, Ernie Posted by Ernie Ghiglione

Hi Ernie Thanks for your prompt reply! Here is an example sequence using the support activity: http://lamscommunity.org/dotlrn/file-storage/view/dotlrn_fs_748413_root_folder/dotlrn_fs_748413_shared_folder/Test_Support_Activity.zip The problem presents itself occassionally in our regular LAMS install and always in our Moodle (via LAMS Two plugin). Many thanks John Posted by John Fitchett

Hey John, Thanks for the sequence. I have managed to replicated your problem. It's quite an odd one, so let me have a thorough look and get back to you. Cheers, ernie Posted by Ernie Ghiglione

Hi John, We have created a bug report for it: http://bugs.lamsfoundation.org/browse/LDEV-2438 You can track the progress on it there. We'll let you know as soon as this is fixed. Thanks, Ernie Posted by Ernie Ghiglione

Hi Ernie Thank you for doing that. I see in the bug tracker that the problem has been fixed, but how do I implement the fix? Should I upgrade my LAMS code to the latest version... or is there a setting or something? Many thanks again John Posted by John Fitchett

Hi John, What version of LAMS are you running? If you are running the latest (2.3.2) I can build a patch and send it to you. Thanks, Ernie Posted by Ernie Ghiglione

Hi Ernie We currently have version 2.3.1. Is a patch necessary? I assume if the bug has been closed that the patch has been incorporated into the current release? Or is this not how it works? If not, a patch would be great! I am sure others would find it useful too. Many thanks for all your kind support and help! John Posted by John Fitchett

John, Update to LAMS 2.3.2 first (see downloads). Once you are up to the latest, let me know and I'll email you a patch to fix this. Cheers, Ernie Posted by Ernie Ghiglione

Hi, I am using LAMS 2.3.3 and recently have the same problem. When trying to view learning sequence from Moodle I ahve the same problem for support activities. It was ok before,I did not understand what happened now though. Can you help me, its a bit urgent as my students started to use the system. Thank you... Muesser Posted by Muesser Cemal Nat

There is an issue fixed in 2.3.4 where if you 'live edit' a sequence and add a support activity, you will get the same error (http://bugs.lamsfoundation.org/browse/LDEV-2510). Is it the case that someone used live edit to add the support activity? If so updating to 2.3.4 should fix it. Posted by Jun-Dir Liew

Hi, I am not sure what do you mean by live editing. However, I tried to delete and new again, it did not work again. At this moment I a bit scared to update LAMS because the system is in use. Thank you, Muesser Posted by Muesser Cemal Nat

Hi, Sorry for double posting. I have updated to 2.3.4 and re-created/imported activities and it worked. Thank you, Muesser Posted by Muesser Cemal Nat
