----------------------------
Fix Version/s: (was: 0.10)
2.0
> internal transition in compound state implementation - SCXML spec
> -----------------------------------------------------------------
>
> Key: SCXML-162
> URL: https://issues.apache.org/jira/browse/SCXML-162
> Project: Commons SCXML
> Issue Type: Improvement
> Affects Versions: 0.9
> Reporter: vance huang
> Priority: Minor
> Fix For: 2.0
>
>
> According to the SCXML spec, the following was stated:
> "The behavior of transitions with 'type' of "internal" is identical, except
> in
> the case of a transition whose source state is a compound state and whose
> target(s) is a descendant of the source. In such a case, an internal
> transition
> will not exit and re-enter its source state, while an external one will, as
> shown in the example below."
> <state id="s1" initial="s11">
> <onentry>
> <log expr="entering S1"/>
> </onentry>
> <onexit>
> <log expr="'leaving s1'"/>
> </onexit>
> <state id="s11">
> <onentry>
> <log expr="entering s11"/>
> </onentry>
> <onexit>
> <log expr="'leaving s11'"/>
> </onexit>
> </state>
> <state id="s12">
> <onentry>
> <log expr="entering s12"/>
> </onentry>
> <onexit>
> <log expr="'leaving s12'"/>
> </onexit>
> </state>
> <transition event="e" target="s12" type="internal">
> <log expr="'executing transition'"/>
> </transition>
> </state>
> Assuming we are in s11 when event e fired. The SM should not go out of s1 and
> enters s12.
> This feature needs to be implemented.
