Re: [Jython-users] extending an existing class -- Makes no sense!

[Andrew J. <aj...@co...>]

Diez-
Thanks for the help!  After much fiddling around, i found what the 
problem was.  It's bizarre, and i don't understand it, and i hope you 
could shed some light on this.
Quick recap: A extends My.Foo.B which implements My.Foo.C.)
with my PyA.py file like this:

import My.Foo.B
Class PyA(My.Foo.B):
    etc.

it works fine, compiles with "compiling module PyA/ PyA extends My.Foo.B"

With my PyA.py file like this:

import My.Foo.B
import My.Bar.X

Class PyA(My.Foo.B):
    etc. (My.Bar.X is unused in class)

It doesn't recognize PyA as an extension to My.Foo.B.  Why is this?  Why 
would an unrelated import change whether or not i had validly extended 
the Java class?

thanks,
A
