NullPointerException in TestAttributeSet

[Karussell]

I'm having problems with a ListView

https://github.com/pivotal/robolectric/issues/193

Here is the full exception* which contains indications that something is wrong with ImageView. But removing the ImageView yields in another similar exception** now with 'Button' problems.

Probably it is really the fact I mentioned in the issue above?

Could someone point me in the correct direction what I could fix in robolectric? I could prepare a test project if someone would have interests to solve this.

Regards,

Peter.

A simple quick fix was to use a normal activity and load the listview. instead of this uncommon usage of a listview with multiple childs. see the issue

Peter.

Is there a way of implementing your own TestAttributeSet and have Robolectric use it, or override the existing one? There's another issue with it that I just raised: https://github.com/pivotal/robolectric/issues/217

Not sure what the proper way is to fix this in the library.
