Failed to signal transition 'approve' from workflow task

Hi,

When we try approve certain tasks in the default Web Site Submission Workflow we get an error saying:


A system error happened during the operation: Failed to signal transition 'approve' from workflow task 'jbpm$88'‍‍

The only thing you can do then is to "Reject" the task.

Any ideas on how to get this particular content through the workflow?

The content in question is a certain Folder in a Web Project.

We are running Alfresco 2.1R1 Community on Linux using MySQL.

I have not yet looked at the log file.

cheers,

Edgar

Hmmm … please open a bug on this.  This needs to get looked into.  Haven't seen myself during testing, but sounds suspiciously like a … ahem … bug.

Has there been any resolution to this issue yet?  I have recently experienced the exact same issue while using Alfresco 2.1Eneterprise and MySQL.

Any chance of seeing the exception stack trace when this error occurs?

Sure, however since I am on a deadline and could not remedy this on my own I have created a new project to continue my development for the time being.  Therefore, I have included all the stack info that was recorded between my attempts to remedy this issue and delete these folders from the project.  I hope this is helpful, and more importantly that there is a fix in the works for this issue since I have a major implementation due to go live in the coming months.  My major concern here is that once the task gets 'stuck' in workflow the files cannot be updated or deleted and have left me with no other apparent option except to create a new project and continue my work there.  This is obviously a significant risk to an implementation that is due to go live and have content on the site frequently updated by an editing team who are not very tech savvy.

Thanks for your response,
Chris
