Some problems in Advanced Workflow

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

Hi! there,
   My users want a workflow like
(document inbound)=>reviewer(assign assignees)=>cosign==>closed.
So, I created a workflow template like parallelreview and a javascript to invoke the workflow. The workflow basically works, but I still have some problems as follows… (( Your help is appreciated! Thanks.. ))
1. Where can I see the whole workflow status?
2. Since I use inbound event to trigger my javascript. I don't hope a document has multiple workflows simutaneously. So, How can I know if there is a workflow associated to this document?
3. How can I set daily notification, if some tasks are overdue?
4. When user approve/reject in cosign, there's an AccessDeny exception

16:30:59,941 ERROR [ui.common.Utils] A system error happened during the operation: Failed to signal transition 'Submit To Reviewers' from workflow task 'jbpm$63'

Hi,

For those still watching this thread: the problem is due to the embedded Beanshell scripting language in jBPM constructing debug information like this :

log.debug("script input: "+inputMap);‍

The inputMap contains the Alfresco Node being worked on. The toString method on this does the following:

return "Node Type: " + getType() + "\nNode Properties: " + this.getProperties().size() + "\nNode Aspects: " + this.getAspects().toString();‍

The getProperties() call fails because the current user does not have permission to read the initiator's home space.

This seems related to issue AWC-896 which is marked as closed (?).

Anyway the problem can be avoided by not using any Beanshell – ie surround your <script> tags with <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript"> (…) </action>
