Hi All,

I'm currently evaluating Jbpm 5.4 for my company and am creating a non-trivial prototype. I have the task service started in a servlet to which the task client connects over hornetq.

I need to be able to display a list of "current" group tasks to a user per process type, so filtered on process id. I can see how the built-in task list queries are executed via the Command object in the TaskClient and how these relate to the queries specified in the Taskorm-JPA2.xml packaged with the TaskService. What I'm unclear on is the best way to go about including my own queries to construct task lists. 

I note the query method on the task client has been deprecated though this seems like the best option I have. Ideally I would extend the TaskClient class and provide my own methods working in the same way as the existing ones. Has this functionality been replaced by something else? Another way I can think of implementing it is via remote calls  to the task server via ejb3 or web services that utilise the task persistence context but this doesn't seem like a good solution. Any advice would be greatly appreciated.
