Hi 

When I open this type of faceplates(PID), only the error is recorded in the diagapp program(There are no messages in the list alarms)

I mean maybe it has nothing to do with this faceplate

Hi,

PCS7 V9.1 SP1.

Exactly the same behavior on any data entry for changing a value.

For instance on MonAn08 from IL Library 9.0. If you key the value (a threshold) and confirm using the OK button by pressing enter on keyboard, the error message will appear. If you confirm the value entry with the OK button using the mouse -> no error. wierd behavior.

Can somebody try this and help ?

Thanks.

I found that the issue is coming from the function APL_CloseArea called from the Keyboard event in

@PG_APL_OA_xx pictures.

But I cannot identify clearly the bug. need further investigation.
