if your exact problem is not seeing #{dBOperator.savedetails} action triggered:

i couldn't figure out the root cause yet, but this problem should be fixed by adding modal="true" to the rich:popupPanel attributes and moving validateFields() function into the popup panel. i faced this problem many times and saw it working properly on different popup components, including this one.
