> Error on resolving conflicting transitions for compound states
> --------------------------------------------------------------
> 
> Key: SCXML-52
> URL: https://issues.apache.org/jira/browse/SCXML-52
> Project: Commons SCXML
> Issue Type: Bug
> Affects Versions: 0.6
> Reporter: Ingmar Kliche
> Fix For: 0.7
> 
> 
> There seems to be a problem on the resolution of conflicting transitions for \
> compound states. See the following scxml document: <scxml \
> xmlns="http://www.w3.org/2005/07/scxml" version="1.0" initialstate="s1"> \
> <datamodel> <data name="x"/>
> </datamodel>
> 
> <state id="s1">
> <initial>
> <transition target="s11"/>
> </initial>
> 
> <transition event="event_1">
> <assign name="x"  expr="'s1'"/>
> </transition>
> 
> <transition event="event_2" target="s1">
> <assign name="x"  expr="'s1'"/>
> </transition>
> 
> <state id="s11">
> <transition event="event_1">
> <assign name="x"  expr="'s11'"/>
> </transition>
> <transition event="event_2" target="s11">
> <assign name="x"  expr="'s11'"/>
> </transition>
> </state>
> </state>
> 
> <state id="s2" final="true" />
> </scxml>
> The state machine enters a compound state s1 which contains another state s11 as \
> its intitial state. Both states have transitions on event_1 and event_2. Note that \
> event_1 has no target, whereas event_2 has a target towards the same state. For \
> event_2 everything works as expected, i.e. only the transition on state s11 is \
> executed and therefor s11 is reentered (I have a listener in my environment and can \
> monitor this).  The error occurs at event_1. On event_1 both transitions of s1 \
> _and_ s11 are executed - but only once. After this, the state machine gets stuck \
> (in particular the currentStates-List is empty). Any subsequent event will not \
> cause any further action.
