[ve-dev] Bean introspection error

["Janak Mulani" <janak.mulani@xxxxxxxxx>]

Hi VE Team,

While placing a ULCCombobox I am getting the following error (VE 1.1.0.1):

In VE 1.0,2.2 this was working fine.

Has something changed? What does the error signify? What should I do to get
rid of this error?

Even after the error the widget is visible on the canvas and behaves
normally.

Thanks and regards,

Janak
