Multibutton added to form causes null pointer

[nickk...@gmail.com]

In the UI designer I've added a multi button to a form, if I show that form I get a null pointer. Stepping through shows this error:

Component not found use UIBuilder.registerCustomComponent(MultiButton, class);

Being thrown from UIBuilder line 413.

As far as I know libraries and plugins are up to date and version is set to latest.

It looks like the statemachinebase isn't generated for some reason when you saved the resource?
Can you think of a reason this would happen on your machine?

userClass, baseClass, package, mainForm, and guiResource properties were all missing from the codenameone_settings.properties file. I put them back but for some reason opening the properties panel in NetBeans deleted them again.

As this project has always been a GUI project from the very start (years ago) I don't know what caused these properties to go missing.

After a few saves and putting the back a couple of times its working now and no longer getting deleted out of the properties file.

Odd. Is it possible someone tried to migrate the project to the new GUI builder?
