Style doesn't change for textfield in UR12 after enabling it

Dear Ladies and Gentlemen,

I ran into an issue in UR12.

After setting a read-only control to enabled (with setDisabled(false)), the style does not change. Instead of the "flat" UR12 style the style is the "3d" style of the read-only field. This issue is new to UR12. When changing the setDisabled mode in previous versions (e.g. UR10v2), the style changed as well.

Does anyone know how I can switch the style of the textfield control to the enabled design in a supported way?

Thank you for your help,

Jan Nebendahl
