Re: Matisse Form showing [invalid component]

Delete the invalid component from the form (in the GUI builder). It appears in
the form when some component used in the form cannot be found - typically you
remove the JAR file from which it was installed to palette, or forget to
compile its class if it comes from another project. When the GUI builder
cannot find the component, it uses a placeholder "invalid component" in the
design. (However - it should never be generated into the code nor saved with
the form as invalid - that is probably a bug.)

the form when some component used in the form cannot be found - typically you
remove the JAR file from which it was installed to palette, or forget to
compile its class if it comes from another project. When the GUI builder
cannot find the component, it uses a placeholder "invalid component" in the
design. (However - it should never be generated into the code nor saved with
