Help in the transition of states in SCXML

[Rajendran, John Tom (STSD)]

Hi there,
I have an orthogonal state chart implemented with SCXML, I have a SLOT
and TASK defined in the parallel states. MSlotInitState to
MSlotHeldState, 
MSlotQueuedState, MSlotLockedState is happening and in the
MSlotLockedState I am trying to 
- <state id="MSlotLockedState">
- <onentry>
  <log expr="'Slot Locked State'" /> 
  </onentry>
  <transition event="SlotReadyToBeHeldEvent"
target="MSlotHeldState.aquireSlot" /> 
  <transition event="TimerExpiredEvent" cond="_eventdata.timeAbs eq
false" target="MSlotQueuedState.queueSlot" /> 
  <transition event="TimerExpiredEvent" cond="_eventdata.timeAbs eq
true" target="MSlotCancelledState.cancelSlot" /> 
  <transition event="CancelEvent" target="MSlotCancelledState.freeSlot"
/> 
  </state>
Move to MSlotHeldState.acquireSlot which is a method call within
MSlotHeldState. Here the transition is not happening. Eventhough the
event is triggered from server side. I am able to go from Init to the
next transitions like MSlotHeldState, MSlotLockedState,
MSlotqueuedState. Next level of transitions are not happening at all. Is
there anything I am missing in the SCXML please help me.
Thanks
John
