Description

when "multiple ok to same node" under decision node, forkjoin validation error.

 

such as below example, 'action_C' and 'action_D' both transition to 'action_E'.

But, because they are under same topDecisionParent 'decision_A', validator will not throw any exception. 

 

<decision name = 'decision_A'>

    <case to = 'fork_B'></case>

    <case to = 'action_G'></case>

</decision>

<fork name = 'fork_B'>

    <path start = 'action_C'/>

    <path start = 'action_D'/>

</fork>

<action name = 'action_C'>

    <ok to = 'action_E'>

    <error to = 'kill'>

</action>

<action name = 'action_D'>

    <ok to = 'action_E'>

    <error to = 'kill'>

</action>

<action name = 'action_E'>

    <ok to = 'join_F'>

    <error to = 'kill'>

</action>

<join name = 'join_F'>

    <ok to = 'action_H'>

    <error to = 'kill'>

</join>

<action name = 'action_G'>

    <ok to = 'action_H'>

    <error to = 'kill'>

</action>

<action name = 'action_H'>

    <ok to = 'end'>

    <error to = 'kill'>

</action>
