i was using build version 2008.2.1001.20 and then upgraded to build version 2008.3.1125.20. both build versions give me this result:
if i use the get_display() property, it always returns false.
if i use the get_visible() property, it always returns true.
i am using a simple example very near the one provided above. i am also showing and hiding rows using the method showItem(index) or hideItem(index).
