Exception: open windows

Hi folks,

since yesterday I get the following exception alert when opening my model:

exception: Exception caught in flexscript execution of MAIN:/project/exec/globals/nodefunctions/openmodelscripts/open windows line 38 instruction 101. Discontinuing execution.

I looked up the executed code, but can't find something unexpected:

37 | inc(node("/nrofpersp",views()),1);
38 | refreshview(window);
39 | if(objectexists(OnOpen(window)))

I can't narrow it down after which change in the model I got this error.

Maybe you guys know more!
Thank you in advance!

Best, Jens

Ok, I think I had some old active views in the tree. I deleted them all, which fixed the exeption-failure-promt in the system console.

But now - If I saved the model with the output console open - I have multiple errors in the output console:

Exception caught in drawstaytimehisto method
Exception caught in drawstaytimehisto method
Exception caught in drawstaytimehisto method
