I tried many things but i didn't solved my issue.

In an visualization frame i would like to run a method by the mouse click event.
If the button is clicked, the method should run (multiply cycles) until the method returns a value.

My issue is, that i can't find a way within the frame.
Do i really use to have a POU which handles the cyclic call?
Isn't there any code behind within the frame possible?

An other way is to use a separate HMI project and map with data sources.
How can i map also methods? Variables, properties and transitions are mappable, why doesn't work methods?

Thanks for your help
