"walking" through a tree in javascript. JDeveloper 11g tp3

Question

Is there a way (or some sample code) for walking down a tree and seeing which rows are disclosed (or expanded); in general getting the TreeState() on the client side using javascript?

Yes, I've read every bit of documentation that you have on the JavaScript API... there is a flaw with you short answer... The default selection mode is none and in our case the row selection is kept unenabled, we use a check box on the node instead for displaying choice, so where one could get a set of row keys from the selection listener... and the disclosure listener... there seems no way get a "complete" set of row keys from the tree. So if the program does not "know" the number of rows there is no way to check each row to see if it is an expanded path or not. And even if one could find the number of rows (which can be done in the RichTree java class), according to the documentation one can not just assume that RowKeys are going to be 0,1,etc... rather "explicit" row keys are needed because the system creates row keys by some magic.
Hence my question is there some way to get the tree state from the RichTree javascript object?
I would "love" it if you told me I was full of it and that if I wanted to know the state of a tree all I'd have to do is...
