As we can not put "start-state" in super-state node then which node executed first? If it depends on order defined in super-state then Why it is not taking the order which I mentioned in process?
This is piece of code

 <super-state name="super1">
 <process-state name="getPrice">
 <sub-process name="Calculate Price" version="1"></sub-process>
 <variable name="productnumber" access="read,write" />
 <variable name="price" access="read,write" />
 <transition to="Calculate Overall Price"></transition>
 </process-state>
 <node name="Calculate Overall Price">
 </node>

 <transition name="" to="Display Cost"></transition>
 </super-state>

One more question if there are two parallel activities in a process-state and no join in the super-state node, then in that case when this super state will be completed? meaning when we can say super-state node completed execution?
