Hi Meghana,

I definitely can't repr= oduce this. =C2=A0Is there any more relevant code you can produce, or even = a self-contained example that shows this bug? =C2=A0I can only imagine this= happening if you defined something called raise somewhere, and even then, = it's hard to work out how it would eventuate ...

However, when I tried to instantiate the sub-class StudentEntryForm(I
have not implemented draw() in Student... and expect NotImplementedError to be raised.), I get the following error:
lib/Qt/qtruby4.rb:2401:in `method_missing': undefined method `raise'= ; for
#<StudentEntryForm:0x000000022c5cc0> (NoMethodError)

=C2=A0 def draw()
=C2=A0 =C2=A0 raise NotImplementedError, 'You must implement draw() in = all of
EntryForm\'s sub-classes'
=C2=A0 end

Thanks!
