I have been trying to use the Bean Palette for a sample written bean. As reported in other posts this functionality is still flacky. I kept getting “The component cannot be instantiated. Please make sure it is a JavaBean.” once you restart the IDE, the problem seams to go away, but then it comes back gain?

The other problem that I ran into is that my JavaBean displays me a messagebox when the Customize option is selected. In M4ME I did not see any messagebox, 🙁 But I found this in the message logs:

!ENTRY com.genuitec.eclipse.dehory 4 4 2006-10-02 14:39:41.375

Attached is my project that I tested this functionality with. The Matisse form is com.itgp.test.test3.java/form, and the control that should be added to the palette is: com.itgp.controls.MyJTextField. Once you add the MyJTextField to the palette, add it to the test3 form. Once MyJTextField in on the form, right click it and select Customize. You should see a text box appear. Instead you get java.lang.ClassNotFoundException: com.itgp.controls.MyJTextField.

Custom components is a known issue, thank you for the example project, we will test with it once we get a bug fix in to make sure it works.
