[rules-users] Drools Flow 5.1.0.M1 - Persistence - WorkItemInfo Entity

[Vijay K Pandey]

Thanks Kris.

This will be wonderful as I have to associate some domain objects (JPA entities) at the work item level.

It is correct that the WorkItemInfo object embeds the values of its

parameters.  We coudl extend that the same way we do for process

instances and variables, to make sure you can use pluggable persistence

for work item parameters as well.  I opened a JIRA for this:

https://jira.jboss.org/jira/browse/JBRULES-2345
