I've got three .xinfo files in my build tree:
Application.xinfo -- no constructors
HierarchialResourceManagerFacade.xinfo -- no constructors
SimpleSplash.xinfo -- two constructors
public SimpleSplash(ImageIcon backgroundImage)
public SimpleSplash(ImageIcon backgroundImage, Component component)
Bingo. I think that's the reason: No default constructor or configuraiton to
address one of the given constructors (if the second solution is possible).
I'm on the way to transform this class to a Merlin component. However, it
needs at least a ImageIcon for the background. How do I handle this with
Merlin? Do I need to have a default constructor and an mutator for the
backgroundImage property? Why not, seems kind of a proper solution... Except
that the Splash may be without background image, which would be nice to be
enforced by passing it in the constructor.
