I have some custom components, suddenly they are shown as invalid component in all forms added.I am tried changing dt.jar location, setting same java version my eclipse ini file and project path.But it does not work.When I run program, it is able to show components.

If I make any changes to form, all component references indicates errors.When I remove component Matisse Custom Palette, add again it gives exception

Can not load component class.the class must be compiled and must be on the classpath of project.
