I found out was wrong when I told everything works fine.

There is another problem:
The Arrays:

$moduleCaller->master_array
and also $moduleCaller->event_array

consist only of events of categories that are selected.

How can I get a list of the events of categories that are deselected.

Example:
Event1 -> Cat1
Event2 -> Cat1
Event3 -> Cat3

If I have only the Categorie Cat1 selected, then there are Event1 and 
Event2 in $moduleCaller->master_array.

But I also need Event3. Where can I find it?
