Tree Grid

http://www.terriblecow.com/awc/ex_row/dyntable.html
I have been studying and trying this example to implement similar approach in one of my project, but I have one issue.

If I click the "+" in one of the rows, it calls expandRow()
and I get runtime error when calling this function.

This is I believe is due to the 2nd and 3rd parameter.
The second parameter has valid value (grida-row-0)
The thirdparameter "row.getProperty("item/index")" always gives me runtime error.

The only difference is that instead of using
var obj = new Active.Controls.Grid;
I am using
var obj = new AW.Grid.Extended;
since when using Active.Controls.Grid, I get ("Active undefined") error. I am using AW 2.0.

I even tried replacing the third parameter with just "index". then inside
expandRow, when doing document.getElementById(rowId), I get "null".

Can anyone please help me if I am missing anything.

Thanks

Also in AW2.0, I am not sure if "Active.Templates.Row" is still available or the librarary name has changed. I am currently using:
var row = new Active.Templates.Row;

But this does not seem to work saying "Active undefined".
Please let me know if anything changed.

Thanks

IMHO ther's no sense in try to convert this kind of V1 sample to ver2.X
( I did try once ).
You can test some nice V2 samples similar like grid in grid or :

Thanks Carlos,
I missed checking ver 2.0 examples. Thanks for correcting me, I will take a look into the link pointed by you and other ver 2 examples and let you know If I have any questions.
