Working with activiti and jbpm workflows

[pylady]

Hello,
I'm using Alfresco 4.2d and I have both jbpm and activiti workflows.
I have to get a list of all completed tasks. For activiti workflows I'm using

NativeHistoricTaskInstanceQuery‍

to search for

HistoricTaskInstance‍

s, and for jbpm workflows I'm getting a list of

WorkflowTask‍

s using

WorkflowTaskQuery‍

.
Can anybody give me a suggestion on what is the best way to work with them together and to put them into one list? Maybe is there a way to convert

HistoricTaskInstance‍

s to

WorkflowTask‍

s?

Thanks in advance,
Jana

For example the Alfresco Task Rest API returns all tasks (jBPM and Activiti) in one query. Did you look at that option?

Best regards,
