$-parameter is still needed despite removing it from the panel

I get the following warnings when I load one of my panels.

The parameter $POPUP used exist in the SurfacePreparation.pnl. But, I have since modified it and removed the parameter completely from the panel and saved it. The panel is working fine. But, I still get these warnings that clutter the log viewer. How do I "rebuild" the SurfacePreparation.pnl so the loader won't complain when it can't fix up this non-existent $-parameter?

I seem to recall this was mentioned as an undocumented feature in the training class and there is a simple work around. But, I can't find it.

BTW, I am using 3.14 patch 4.

So if I understand it correctly you have remove the dollar parameter '$POPUP' from the panel 'SurfacePreparation.pnl' and you get the errors. Is this correct?
Does the panel 'objects/IODateTime.pnl' also have the dollar parameter '$POPUP'?

Maybe you reference have overparemetriztion. You changing original panel, but overparametrization reference dont changing

I went back to the SurfacePreparation.pnl and opened it using the Edit | Edit Panel Scripts editor. I found that I was still referencing $POPUP in the initialization handler for one of the graphic objects in the panel. I was not aware this object had an initialization handler. The Edit | Edit Panel Scripts helped to make this obvious.

Thanks for the replies.
