After a succesful deploy of my custom Workflow, when I start it from Share it says it cannot start.
Share log says:

Don't know where to go… Just one thing that may be particular in what I do, I don't use a custom model, my activiti process refers to built-in tasks already living in alfresco/classes/workflow/workflowModel.xml. To be explicit, this is my context file:


<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

<beans>

Where is the problem? In the process definition? In the context file?

Any help appreciated!

It seems like it'the same error presented in these threads, <a href="http://forums.alfresco.com/forum/developer-discussions/content-modeling/constraints-create-bug-01312..." >here</a> and <a href="http://forums.alfresco.com/forum/end-user-discussions/alfresco-share/redering-custom-model-broken-42...">here</a>. Ther is also an open <a href="https://issues.alfresco.com/jira/browse/ALF-17730?page=com.googlecode.jira-suite-utilities:transitio...">issue on JIRA</a>.
But I am a little surprised because in my case I'm not using custom model at all. Simply the workflowModel already living in alfresco/workflow.
Anyone? In the meantime I'll try to figure it out how to customize the form, maybe via share-custom-config file. Don't know if it's the right way.

You shouldn't need the model property if you're using the oob model, they are already there. Can you post your workflow.xml?

as you can see it is absolutely straightforward. I simplified it the most just to see if I can use it. But I can't even trying to start a wf instance from the workflow console.

koopa · ‎02-21-2013

I tried to start from a clean space, so I started a new tomcat with fresh alfresco and share war on a fresh new db but the result is the same. Created process with eclipse activiti designer, created my custom context file to make the new process visible, linking it to alfresco/workflow/workflowModel.xml, started tomcat, launched wf via UI… fail.
But I did a step forward, I can now start it from the wf console and really see the detail wf form once started. This is my new baby-written process:

Copy-Pasted both processes on 4.2.b and they work.

bprado · ‎02-22-2013

I had exactly the same problem. Same solution as well, thank you.

nyorai · ‎07-07-2013

I had exactly the same problem, just starting out learning Alfresco and spent a whole weekend scratching my head. Turns out I wasn't doing anything wrong after all! 4.2b works fine.
