Hi,
I am not sure I understand your problem...
Apparently you have 2 events that require the current value of a latch boolean, is that it ?
If yes, in the event "value change" made on the button you don't need to actualy have the button in the event to get the value. In this event, you can get both the new and old value of the boolean from the "thing on the left hand side of the structure.
As Altenbach said, some code with a simple example would helps us provide better advice
