Task Query (All Tasks)

pneudecorb — Thu, 17 May 2012 23:28:53 GMT

Is it possible to query the engine for all tasks, even ones that haven't been reached yet in the current execution, If so, how?I'm creating an onboarding workflow and I need to be able to display all the tasks whether they are active or not.

Why would you? I you could show them (depending on you flow, some might never be reached) you could not act on them.

Please state your usecase…

I understand how a workflow engine works and I understand that some activities may never be reached depending upon how that process definition is designed.

I am using the workflow engine for an onboarding process and whether or not a segment in the flow will be reached at run time, I still need to present to a particular user, which activity(ies) they could be responsible for….

For example, consider you have a simple on boarding process with the following activities

1) Provision Laptop
2) Distribute Laptop
3) Assign Access Badge

Now consider that activity 1 and 2 are both done by IT but activity 2 is gated (blocked) until activity 1 is completed.
Activity 3 is performed by HR.

I have a requirement to present ALL the possible activities to each user, so in this case,

The IT user would have both Activity 1 and 2 as their future actionable items even though Activity 2 might not ever get activated in the flow.
The HR user would have Activity 3 show up in their list of activities.

Makes sense?

I'm currently investigating the Process Definition Query functionality available through the Repository Service.

It looks like I can get to the task information I need by casting my single result to a ProcessDefinitionEntity.

My thought of querying for a Process Definition, casting it to a ProcessDefinitionEntity didn't bear fruit…when I check the instance variables for defined activities, it returns an empty list, so I am still unable to identify all the task definitions for a process definition.

Any ideas?
