Hello,

I have a database running on an IOC running an ai record named '$(SubSys):$(Device):Read'. I display the value in the record using EDM with the Text Monitor widget (I have tried other widgets but they all have the same issue.) The precision is set to get the precision from the database, which it does.

In the database I have ao records that push different precision values into $(SubSys):$(Device):Read.PREC dynamically. I have checked and the values are indeed being placed into the PREC field correctly.

The problem is EDM doesn't redraw the widget to incorporate the changed PREC values. I tried putting Text Monitor widget on a different screen, opened by a related display button, but even when the new window is opened; it doesn't redraw the Text Monitor with the new precision (VAL is updated correctly.) If I close EDM completely and restart it, the new precision values are reflected correctly. This leads me to believe that EDM assumes PREC fields to be constant upon initialization, is this correct? If so, is there any way to change this?

If anyone has encountered this problem or knows a work around I would appreciate the help.

Thanks,
Mathew Hicks
