Description

I have not located the code where this is happening. Anyone have any idea what it might be?

Hello,

Background: this error means that a signal for a disabled item (e.g. a disabled button, or an invisible button, a button that was deleted, ...) has been triggered. It is a security feature of Wt: things that cannot be clicked, should not generate signals.

There are a number of legitimate cases where this error may appear, e.g. if an event deletes a widget, but the same event was also handled by other widgets. Does the error cause the program to misbehave?

Best regards,

Wim.

It occurs when i move widget to another application and ui controls (Wt too) become useless.
