General :: Porting TW Package From Samsung ROM To CM?

I'm trying to port some package from Samsung ROM to CM following this guide and I'm stuck.I decompiled the package, removed TW dependency from the manifest and now I'm adding additional classes from TW framework into this package. Everything was smooth so far as I was getting rid of "class not found" and similar messages in logcat by adding the missing class and recompiling the package.When I try to run the app, I get the following message in logcat:

Code:
I/dalvikvm(30301): Could not find method com.sec.android.touchwiz.widget.TwAbsListView.isInDialog, referenced from method com.sec.android.touchwiz.widget.TwAbsListView.onHoverDrawableState
W/dalvikvm(30301): VFY: unable to resolve virtual method 9561:
[code]....

However, based on official documentation this method does not exist in this class.If I try to add android.view.ViewGroup and android.view.View from stock framework.jar into the package explicitly, I start getting "multiple definition" messages in logcat, and isInDialog still can't be resolved.So, I'm currently stuck.
