Hello Michel,
you explained it well enough...
First - we zoom modules that contain a panel (you dont zoom the actual panel but only the module where a panel is contained).
Now to the actual problem:
The zoomn mavigator is a reference that has a $-parameter $ModuleName.
Here you should give the name of the module you like to zoom.
Example:
If you use the panel topology and you insert the zoom navigator in the navi-Panel then of course you want to zoom the panel inside the mainModule and not the naviModule.
Therefore you have to give the correct module name - now here is a little problem with multi monitoring.
The existant reference only has one $-parameter for the module name and if you would state there "mainModule_1" (that is the name of the main module on the first screen all of those buttons (on second and third screen) will everytime zoom mainModule_1
therefore you have to change the script a little bit:
use myModulename to find out on what screen the button was pressed (extract the postfix number behind the "_")
and this number you add to your static "mainModule_".
"mainModule_" + screennumber
best regards
Markus
