Simulation subprocess

Hi all:

I'm doing the simulation of Subprocess  that contain pools and the following occurs:

In the following model,  the simulation is done correctly,  ie the sequence of the simulation is started from the event 1 , after that  go to  message end event then  starts with the message start event.

Fig 1

 

but the next model uses a subprocess associate to model 1(Fig 1), the tool(Oracle bpa ) simulates the subprocess starting  both events simultaneously (Fig 1 Event 1 and Message start event) and at the end of the simulation throws the following error:

 

"Message start event" in "Model 1": Unable to find an incoming message flow for the object. "Message end event" "Pool": Unable to find an outgoing message flow for the object.     Fig 2   My question is there a setting to simulate the Fig 2 so that the "Model 1" process runs without throwing the two events at once, ie  starts with event 1 and continue the flow of events through message events?   Thanks for your help
