> Allowing the target of a transition to be omitted
> -------------------------------------------------
>
> Key: SCXML-14
> URL: http://issues.apache.org/jira/browse/SCXML-14
> Project: Commons SCXML
> Issue Type: Bug
> Environment: Windows, JDK 1.4.2
> Reporter: Sitthichai Rernglertpricha
> Assigned To: Rahul Akolkar
> Priority: Minor
> Fix For: 0.6
>
> Attachments: patchfile

>
> Currently, the runtime throws a ModelException if the target of a transition
> is not specified.
> E.g. the following throws a ModelException since the <target next="..."/> is
> omitted within the <transition> element.
>
> <state id='s'>
> <transitionfiltered="xxx">
> <assign name="data" expr="value">
> </transition>
> </state>
>
> However, based on the scxml specification at http://www.w3.org/TR/scxml/ at
> section 3.3, quote - "If the "target" on a <transition> is omitted, then
> taking the transition has the effect of leaving the machine in the same state
> after invoking any executable content that is included in the transition. "
>
> The attached patch can be applied to the ModelUpdater.java to fix the above
> problem.
> Basically, the change is in the updateTransition() method. If next variable
> is null, return immediately from the method.
