Grid DataModel keeps data in memory

[tane]

Hello , I am newbie at yui-ext and yui-ext is THE THE most js lib I saw.
Thank you Jack.

Anyway I have litle problem I use Xajax for creating array to supply my js function which is loads
in my init.js.
Basicly my idea work like this.

init.js -- loads grids and other stuff
the i have litle

function load_nzp(mydata_array) {

This setups the grid and shows it .
}


now from xajax i call load_nzp(mydata_array); and send my array

Now everything display good , but then i try to do a click event and take data from grid.

Then I tryed this.

 
var onRowClick = function(grid, rowIndex, e) {
                 
                        qq=grid.dataModel.getValueAt(rowIndex, 0)
                        alert(qq);
                        
                        }
     

     var grid = new YAHOO.ext.grid.Grid('inner2', dataModel, colModel);
      
      grid.addListener('rowclick', onRowClick);

     this.grid = grid;
    
     grid.render();

Then I try to load againg some ether data into the grid.
Everything display fine in a grid.
But when i try to click on grid row I get old data and get two alerts oldvalue and new value.

So evry time when i call from xajax load_nzp(new_data_array) i get oldarrays+new_data_array.

Probably my concept is not good or I am mising something.
So if somone would be kind to help with this problem i would be very greatfull.
Thank you

I made some example do demonstrate the problem here is the url

http://tane.grappoloin.com/yui-ext/e.../xml-grid.html

just clik on data1 or data2 button then click on some row in grid

you will see the problem.

I probaly doing something wrong but I just do not have clue what is it

Well, you're calling XmlExample.loadGrid when the button is pressed.

That's already been called once. You're adding that function as a listener again!

Basic organization! Init the grid and listeners in the init function! load the grid in the load function.
