delete-event : Erases member data in class?

Hi all, Im going to try to explain this as thorough as possible without having to post too much of the code. But the just of it is I have a window class that uses another window class for error displaying and calls the error classes "show" function and passes it a callback to a function within itself. $this->kWarningMgr->show( array( $this, "close_wdwWarning" ) ); Then in the error class the show function looks like this ... function show( $close ) { $this->eventClose = $close; $this->window->signal_handler_unblock( $this->hndFocus ); $this->btnAccept->grab_focus(); $this->window->show_all(); } Here everything is fine, if you use print_r( $this->eventClose ) it spits on the data in the array. first element an object and the second a string to the "close_wdwWarning" function in the calling window class. When the delete-event or even the destroy event is fired. function delete_event( $window, $event ) { $this->window->signal_handler_block( $this->hndFocus ); $window->hide_all(); call_user_func( $this->eventClose ); return true; } The data in $this->eventClose is gone. However the data in $this->hndFocus echo out the id of the signal. I have tried a billion things and I can assure you that the $this->eventClose is NOT being nulled anywhere in the code. Anyone else had weirdness like this? If asked I can post the entire code for them for the two classes in question.
