Hi guys!

How should I handle errors in subflows? Let say I catch exception during executing the action in subflow. Should I explicitly define transition to the end-state on="error" in this action state or it is just enough to throw error event without showing transition?

Here are some snippets. In main flow:

Code:
<subflow-state flow="tools.DoSearch" id="tools.DoSearch">
	<attribute-mapper bean="searchType.attributeMapper"/>
	<transition to="selectSearch.view" on="finish"/>
	<transition to="error" on="error"/>
</subflow-state>
and in subflow:

Code:
<action-state id="retrieveAction">
	<action autowire="byType" method="retrieveStudiesFromArchive" class="StudyAction"/>
	<transition to="overview" on="success"/>
	<transition to="finish" on="error"/>
</action-state>

...

<end-state id="finish"/>
In code above I have transition to the end-state on error during action execution in subflow, and in definition of subflow I have transition to the error page if subflow execution finished with error. Is it right or I miss something?

Additionally, I read in docs that subflows can return values. Could you please give some more info about it and some examples?

Thanks a lot in advance.

Cheers,
Fuad
