Advanced workflow on an 'invisible' space

Hi all,I have a situation here where I want to start a workflow on a document, which is placed in a space where other people don't have access (not even consumer permission). When the advanced workflow is started, the reviewer can see the task, but can't see the document (resources), which is not wh

Hi,

use script or java actions after the start-task to create custom permissions suiting your needs.
See http://wiki.alfresco.com/wiki/WorkflowAdministration to know how to call script or java actions in a workflow process definition.
See http://wiki.alfresco.com/wiki/3.1_JavaScript_API#Permission_and_Security_API to know about permissions scripting API, or http://dev.alfresco.com/resource/docs/java/repository/org/alfresco/repo/security/permissions/impl/PermissionServiceImpl.html to know about permissions JAVA API.

hope this helps

Hi,

Thanks for your quick reply.

I am using an enterprise edition of Alfresco. How do I create my own xml with a jboss designer?
Can you be a little more specific, please? Does that mean that I can create by hand my own xml file and give the selected people other permission when this customized workflow is started?

Regards,
Jenny

Yes, and as workflows are quite complex, I would need about three days to write a complete explanation about what I said.
I think the best thing to do for you is have a look at this perfect tutorial :

Thanks again.

Hi all,

I am overwriting the permission for a reviewer and after the workflow is ended, all the permission will be removed from the reviewer. This works fine for the workflows that I've modified.
I'm still not able to do the above, when the reviewer choose for a reassign.
Here I have an example of my adhoc_processdefintion.xml , which is OK.

Jenn_l,

If you were able to get this working consistently in your own custom workflow, I would love to see the final solution.

Thanks,
