Grid with JSON data and Struts

Hi,
I am a new user of DHTMLXGrid and I have some issues in my project. I have a grid I load with a JSON variable, it work perfectly (you can see the result here : img27.xooimage.com/views/2/7/5/m … 666c3.gif/).
Here is my issue : in my action STRUTS, I don’t succeed to get which checkboxes are checked when the user press the button “Envoyer” (=send). It seems that my JSON object is not updated. Here is a part of my code :

[code]


... var mygrid = new dhtmlXGridObject('gridTypesVarScenar'); ... mygrid.init(); var dataJson = ; mygrid.parse(dataJson, "json");[/code]

Can you help me ?

I don’t succeed to get which checkboxes are checked when the user press the button “Envoyer” (=send).
Are you able to see alert when you press “Submit” button. We tested this code and it works without issues.
