Description lordy 2005-11-04 23:03:54 UTC
[ BUILD # : 200511031800 ]
[ JDK VERSION : 1.5.0_05 ]

I try to use CloneableTopComponent in FormEditor.

* New File
* choose "NetBeans Module Development"
* choose "Window Component"
* next next next finish
* change "final class testTopComponent extends TopComponent 
{" to "final class testTopComponent extends 
CloneableTopComponent {"
* change to designer view
* i get a exception... "check if it real a javabean"

I take a look at the CloneableTopComponent source and see that 
it is a abstract class which extends TopComponent. I wonder a 
little around that and try to find a way to fix it.

I was able to fix it. I want to use CloneableTopComponent, but 
i'm not sure if this is a good solution. But i'm interessed what 
you think about.

Thanks for the idea and patch. I think we could do it this way, i.e. find the
first non-abstract class if the form superclass is abstract. The user will be
cheated a bit - as the class the form editor works with is different than
declared superclass, but it is perhaps better than if it can't be edited at all.
Should consider a warning.

An enhancement for a future release.
