The problem seems to be that I keep the Image in a static variable
under the (probably wrong) assumption that I could save some memory
when multiple of such buttons are used. Changiong the definition to
public class AddButton extends PushButton{
public AddButton() {
super( ImageCollection.getImagesInstance().add().createImage())
;
}
}
makes the button behave fully as expected. I don't need the deferred
command anymore.
So case closed.
