How do I get multiple widget instances?

Hi everyone!

I’ currently developing a plugin which will work as a widget. I have managed to get support for multiple instances, but there is one small problem… When I save the settings (one text field, three radio buttons and one checkbox) the only thing that gets saved is the text field.

Is there any example out there? if anyone of you guys have some ideas it would be greatly appreciated.

EDIT: I might add that if I create text fields with the same name as the radio buttons or checkboxes the data gets saved just fine…
