My Tasks - Always Fails

[theslacker]

Hi all. I downloaded Alfresco Community 3.3 and am evaluating it for my company. I really like some aspects of it, but I am having trouble with one feature right out of the box. I installed on win XP using the exe installer. Install went well. Using Share works well except whenever I try to do anything in the My Tasks Dashlet, it never works. I get a Failed To Action Task message.

Here is an example:
- User requests access to site
- site owner has the activity in My Tasks to approve or reject
- site owner clicks either option and the Fail message comes up

I tried a whole variety of other tasks and they all fail.

Another example is accepting a workflow request.

I looked in the error log and one error I've seen is "Invalid Global ID" errors.

Any ideas? I really want to get this working as Alfresco looks awesome. I would think that out of the box the features would work.

Thanks!

I'd really like to see a post telling us what to do about this other than wait.  We spend a lot of time chasing and reporting bugs and could use some help killing them.

I'd really like to see a post telling us what to do about this other than wait.  We spend a lot of time chasing and reporting bugs and could use some help killing them.

The best way of tracking bug fixes is to watch our SVN checkins, either via twitter (@alfrescoeng) or SVN directly. We'll be opening up a Fisheye server too soon (I don't think it's public yet, as we're still testing internally).

The fix you want is detailed in http://issues.alfresco.com/jira/browse/ALF-260 which refers to SVN rev. 19829

Thanks,
Mike

thanx for the answer
can you tell me the path in svn?

There are some great SVN help resources available from a quick Google search… however:

$ svn diff -c 19829

my problem seems to be there again after the change..my log file says

Caused by: org.alfresco.scripts.ScriptException: 03200003 Failed to execute scri
pt 'classpath*:alfresco/templates/webscripts/org/alfresco/repository/workflow/en

Thanks Mike,

Changed that one line and the My Tasks dashlet is working correctly.

Hi,

I changed ./tomcat/webapps/share/components/dashlets/my-tasks.js but I still get an error when trying to complete tasks. Have I overlooked something?

I checked out HEAD and did a diff with my edit against HEAD and the file is the same as far as I can see. I've restarted Alfresco, too.
