Delete Parent Container shape if Child Shapes are deleted [message #1682169]

I have this feature requirement where I am trying to delete the parent container ,when child Shape is deleted. But I am getting this error even though I have used
TransactionalEditingDomain editingDomain = TransactionUtil.getEditingDomain(containerObject);
editingDomain.getCommandStack().execute(new RecordingCommand(editingDomain) {
@Override
protected void doExecute() {
}
});

to execute my code

I am trying to call the deleteFeature for the parent containerShape from the moveShape() of the Child.

I'm not sure, but i think you try to execute this command in another command. (Features are wrapped in commands). Have you tried in the DeleteFeature's postDelete hook?
