Bug 72282

Description Matt Rossner 2004-08-19 11:21:27 EDT

I am using Eclipse 3.0 build 200406192000

In the Java editor when a method is overridden, then is a little green arrow 
that appears in the left margin, if you click it, it brings in the code from 
the parent class. But if the parent class code is unavailable, like from 
Object.class, I get errors. If I override toString() and click the green arrow 
I get this error dialog: "Unable to create part", and this entry is created in 
the .log file.
