Current selected row index

How can I get the current selected row index using AW2?

i've tried var index = obj.getSelectionProperty("index"); and it doesn't seem to work. Is there another command to do this?

I am called the function when I click on a button.

Have you even looked at the samples that come with the framework? If you do, you will see that getSelectionProperty("index") is not used any more. If you have 1.0 code that you are trying to use with 2.0, then you are going to have to re-write almost everything. Start from scratch, but frist read the examples that are provided with the toolkit.
