PostUUTloop not executed in ParallelModel

Hi,

I am customizing a operator UI, it requires sequence to run in default station process model ParallelModel.seq.

I have two buttons on the UI dialog.
1.One is connected to SequenceFileViewMgr with command CommandKind_ExecutionEntryPoints_Set, this one is used to start Test UUTs , launch all executions, it runs properly as expected.
2.Another one is connected to ApplicationMgr with command CommandKind_TerminateAll, this one is used to stop all executions following process flowchart, it is expected to call PostUUTLoop and stop, but actually, teststand doesn't call PostUUTLoop.

I don't know how to control engine to run following flowchart completely, as PostUUTLoop is used to de-initiate and release resources.
