Delayed reaction when using fieldindex formula to hide sheets

[#1]

How can I get an immediate reaction when using a fieldindex formula to hide/show objects/sheets:

I have the following small example:

QVAdminUsers:

Load * Inline [

    ID, MUID, User

    1, Alltag, CHE

    2, RemoteAdmin, RSO

] ;

SET F_CheckIfAdmin = [fieldindex('MUID', subfield(OSUser(), '\', -1))] ;

result is correct: MUID Alltag has fieldindex > 0

if I change now User 1 to xAlltag I get the correct result of the fieldindex formula but the sheets do not react immediately

I need to click something like a field in the table or on one of the other sheets' tabs (clicking on the Admin-sheet tab is doing nothin because it is not a changing activity I assume) to get the correct result:

How can I get an immediate reaction

More worse happens when opening in the AccessPoint on QV-Server. There the fieldindex result is corect but the sheets do not react.

Any idea if this is a bug or any way existing to avoid this behaviour ?

Thanks for any help

This is identified as an documentation error in the manual. Currently the function should only be used in chart objects. To expand this I added an idea... - to vote for it search for fieldindex
