Hi,
I have recently decided to create a new project based on another.
I copied all my old classes to the new project, but some of them I had to
reorganize into new packages. Both projects are now defined in Eclipse
3.2.0, but the old one was developed in 3.1.1. Java SDK version is 1.4.2.
The problem appears when I try to open a visual component class that
doesn't extend directly SWING's JComponent but its subclass written by me.
Visual Editor cannot visualize a form in right way. It displays exception
messages like those attached below.
Described problem appears ONLY in new project. Component visualization in
old one stayed OK. Cleaning the project, rebuilding, switching to other
version of Eclipse (3.1.1, 3.2.1) do not affect.
Is there a cure for that? Can anyone help?
Regards,
Peter
