SideMenu shadow NullpointerException

[Mario Barón]

Hey guys,

I want to report a Nullpointer exception when setting the theme constant "sideMenuShadowImage" on the GUI Builder on the CN1 simulator. I haven't tried it out on devices yet but on the simulator the following error appears:

java.lang.NullPointerException

Hope this is useful for detecting the problem.

Thanks.

Hi,
we'll fix this but the workaround is simple. If you define that flag you must also define the sideMenuShadowImage to point at an image of the dropshadow.
