Can I mark a transition to end-state inside Decision node.

[ambrish_kumar]

Hi All,


I have a process definition, which is given below

<start-state name="start">
        <transition to="approvaldecision"/>
    </start-state>
 
    <decision name="approvaldecision" expression="# {myBO.checkOrganization}">
        <transition name="approval" to="approval"/>      
        <transition name="approve" to="complete">
        <action expression="#{myBO.approved}"></action>
        </transition>       
    </decision>

<end-state name="complete"/>

Now the problem is that when I call the function approved() of
myBO.java then it gives following exception

10:30:09,346 ERROR [SeamPhaseListener] swallowing exception
