--------------------------------------
Summary: Support of special send targets #_parent and #_invokeid
Key: SCXML-226
URL: https://issues.apache.org/jira/browse/SCXML-226
Project: Commons SCXML
Issue Type: Bug
Affects Versions: 0.9, 0.8, 0.7, 0.6, 0.5
Reporter: Michael Goerlich
Currently it is not possible to use #_parent and #_invokeid to allow
communication between two scxml instances where one invoked the other.
Due to the last changes the _ioprocessors variable was introduced. If the
target of a <send> may reference to an entry in the _ioprocessors map, then it
should be possible to forward events directly to the registered
SCXMLIOProcessor instance.
Given this the invoker must supply a SCXMLIOProcessor for the parent to
register within the its SCXMLExecutionContext map as #_invokeId and the invoker
must register the parent SCXMLIOProcessor as #_parent within the execution
context of the SCXMLExecutor. As well as this the EventDispatcher must take the
SCXMLIOProcessor registered for the target from _ioprocessors.
Based on my assumptions I tried to implement this and uploaded the patch to:
http://pastebin.com/t855Ugs1 . Hope it helps.
