Hello,
I'm using Alfresco 3.4e.
I've modified Alfresco content model adding a new property status (Draft, Validate, …) to cm:content node. I've developped the following workflow in order to change the status of the document related to the workflow.
Here is the workflow process definition :
erson in type mbswf:validateByTeam_teamSelection). Each selected user has a validation task.
validation task has a timer which triggers "ok" transition after 5 minutes.
SetStatusNameAction and SetStatusNameAndDateAction classes change properties of document in the workflow package (status and status validity date).
As an example, here is my SetStatusNameAndDateAction class :
When the transition "ok" is triggered by the timer, I get the following error in my logs :
Developments related to this workflow are the only changes made to Alfresco 3.4e.
I have no error when a user is taking my transitions.
Thanks for your help. Do not hesitate if you need further informatios.
