Post by manuknecht on FileDialog - OnDialogClosed not called anymore CODESYS Forge talk (Post)
I had similar issues with the OnDialogClosed not being called. I realized that this behaviour is resolved, when the according visualization object on which the input configuration is set is moved to the foreground. Somehow, the object has to be one of the lowest elements in the Element List (i.e. in the foreground) for it to work.

Post by benemenn on Type mappings in Datasource CODESYS Forge talk (Post)
Hi! I am trying to achieve the same issue. Has there been a solution? I can create the mapping, and map the local variable, but somehow the object does not update. Furthermore, i have an issue where codesys doesn't let me set ReadWrite accesses to the variables in the "Type Mapping" place. The access will simply not be set. Has anyone ran int that issue?
