scxml: nested custom actions

Hi Ate, Woonsan, 

Is there a way to access nested child actions from a parent custom action in scxml? 

In version scxml-2.0-M1 I could do this in the onexecute of a custom action: 

for (Action action : getParent().getActions()) {
       if (action instanceof MyChildAction) {
              // do things with child action


In M1 the Executable.getActions() would list all actions, also the nested child actions contained in a parent action.  In the most recent code the Executable.getActions() only lists the parent action, NOT it's children. 


I want to do something like this: 

<onentry>
         <ntd:parentAction>
                    <ntd:childAction ... />
                    <ntd:childAction .../>
         </ntd:parentAction>
</onentry>

So how to access the childActions from the parentAction's onExecute? 


thanks in advance, 

Rinke

Hi Rinke / Ate,

It looks like it has been changed as of SCXML-213 [1] with commit
eba2b2899787ef0476c1dd8852aba5b0adb4f5f3.
SCXMLReader#readCustomAction() seems to ignore the possibility of
nested custom actions by invoking #skipToEndElement(reader).
@Ate, is it probably a regression? (custom actions are commons-scxml
specific, not having to be compliant with scxml spec)

Regards,

Woonsan
