Fire the UnifAce \"TRIGGER\" synchronously when OCX send an event to UnifAce
When using an OCX widget, it is some times necessary to answer synchron to an event. Think about an widget which will print out lines of data and need more information about the data send. In this case, the OCX will fire an event to get the missing data. If the UnifAce TRIGGER is fired at the end of processing, this events are useless.
