Description Jiri Vagner 2007-05-28 14:45:13 UTC 
Steps to reproduce:
 - create jframe
 - create jlabel
 - invoke popup menu for label and run "Bind -> text"
 - in binding source listbox select for example "Form"
 - in binding expression type "${text}"
 - press OK button
 - invoke popup menu again and again run "Bind -> text"
 - press OK button (you can also delete content of textfield)

I know that there is a treecombo with valid values, but binding expression input
contains "textfield" and anti-mouse user will use it as textfield. So it should
be nicer to user's type errors.
