Workflow failed to signal transition 'null' from wrkflw task

[jenn_l]

Hoi All,

I have deployed my customized review_pooled_processdefinition.xml in Alfresco 3.2r Community.
When I tried to start a pooled workflow I get the following system error in my webclient:
Please correct the errors below then click Finish.
system error happened during the operation: 02170018 Failed to signal transition 'null' from workflow task 'jbpm$77

The second time I tried I get this:
Please correct the errors below then click Finish.
A system error happened during the operation: 02170020 Failed to signal transition 'null' from workflow task 'jbpm$78'


The catalina.out displays this:

The funny thing is that this processdefinition.xml works fine in Alfresco enterprise 3.0 and Alfresco enterprise 3.1.
Can anyone help me out ?

Thanks in advance.
Kind regards,
Jenny

Failed to signal transition 'null' from workflow task

This message is frequently generated when there is a workflow syntax or other problem with the workflow definition.  Further down in the log and perhaps the last error in the log is usually the real issue.  Posting more of the log may help find the problem.

I now know that the problem has to do with retrieving the groupname in my processdefinition.xml. That's the usr:authorityName part of the XML. It seems like 3.2 has another definition for retrieving the groupname. In 3.0 and 3.1 I can get the groupname through javascript using "usr:authorityName" and 3.2 I get null.

Any help on this?

Regards,
Jenny

[stevegreenbaum]

I don't know what would make this not work in v3.2, but try changing the statement a little to see if that help.  Just a guess.

 

var group = bpm_groupAssignee.properties["usr:authorityName"];

Try this:

bpm_groupAssignee.properties.userName;
