8,243 PointsClassCastException
Hello.
I keep getting a ClassCastException and I'm not sure how to fix it:
09-07 15:03:45.727 31235-31235/com.x.x W/Bundle: Key note expected Serializable but value was a com.x.x.items.Note. The default value <null> was returned.
09-07 15:03:45.737 31235-31235/com.x.x W/Bundle: Attempt to cast generated internal exception:

It tells me the error occurs when I cast my note object to a serializable:
mNote = (Note) intent.getSerializableExtra(getString(R.string.note));
Please help!
