This exception happens when an invalid name is set to a component in GUI builder. The exception is created by the model component (RADComponent), annotated, and thrown. RenameAction catches the exception and reports via Exceptions.printStackTrace(). Because the exception is annotated, a nice message dialog is shown. But somehow sometimes the exception is reported as a real exception - like in this report. It must be a problem of ErrorManager or the way the annotated exception is reported.
