Triggers not working in subpages

Good morning everybody,
i have a problem with a certain structure and the default triggers INSERT,MODIFY,DELETE.
I wont describe the thing in the small parts, as the solution may be so small and simple that i can’t find it :smile:

The structure is formed by a main page and 4 subpages that show different parts of the main page, also they follow this hierarchical order: Subpage1 shows macroareas, Subpage2 shows all the micro areas in the selected macro area in subpage1, and subpage3 and subpage4 follow the same pattern.

If i insert,modify or delete a trigger in subpage1 and subpage3, the triggers will work and the action will be permanent after i refresh the page; but if i insert,modify or delete a certain record in subpage2 and subpage4 the same will not happen, as the trigger haven’t been fired. I checked that all the properties and structure and code are the same for all subpages, plus they all refer to the same main page, so i can’t really figure out what the problem is.

Can you please give me any suggestion?
