Description Tomas Schlosser 2012-02-23 06:58:39 EST
Description of problem:
API does not provide any way to register work item handler in StatelessKnowledgeSession. If the process containing WorkItem node is started, the exception is thrown saying "Could not find work item handler for <whatever>".

Comment 1 Kris Verlaenen 2012-02-28 18:45:43 EST
When using a stateless session, the session is always created upon request and disposed at the end of the invocation.  There are however two ways to set a handler:

 - using a configuration file in the classpath that defines handlers
 - by adding a RegisterWorkItemHandlerCommand as part of the commands you are sending to the stateless service to first register the handler and then execute the rest of the commands

Would this be sufficient?

Comment 2 Tomas Schlosser 2012-02-29 02:13:41 EST
That should dod the trick. Thank you Kris.
However I have one more request: could it be added to CommandFactory? I use it (since it is the official API) and don't search for Command implementations anywhere else. If it would not be possible, please add it to documentation.
Thank you.

The method newRegisterWorkItemHandler() is still unavailable in ER6. Ryan, did this code make it into ER6?
