Description carsten.driesner 2008-10-06 16:06:21 UTC

OpenOffice.org dispatch objects don't call disposing although they implement the
com.sun.star.lang.XEventListener interface. There is a severe problem for
external developers who don't know when a dispatch object gets invalid. There
are only workarounds possible, e.g. using a FrameActionListener and react on
COMPONENT_DETACHED, to invalidate dispatch objects. A correct framework solution
would use disposing to notify listeners.

cd: Accepted. The following projects must be checked: sfx2, dbacess and chart2

Comment 2 Mathias_Bauer 2008-11-18 16:22:50 UTC

All StatusEventListeners must be removed from their Dispatch objects when the
StatusEventListener's environmenal component is going to be destroyed, e.g. when
a frame "owns" the listener and is closed or when a component "owns" it and the
frame is reused for another component.
