Dgrid + Selection Issue - dgrid

Question

Still trying to work with Dgrid (0.4) and dojo (1.10), I have now another issue with the selection.
My web page contain a Dialog opened when you click on a button.
Inside this dialog, we have the following code which display a grid with data coming from a database through a Json HTTP page. This is working fine, even sorting and query filtering.
What I want to do know is to allow the user to double click on a row, get the selected row Id contains in the first column to update the form in the main page. I use the dgrid/selection for this. However, it always return the last row of the grid instead of the one the user selected.
The selection code is based on this :

Any idea?
Thanks

Answer 1

Just found the reason.
the columns need to have a 'id' column called ID. I just change the 'contact_id' column to 'id' and it works fine.
thanks
