    Default Grid DataModel keeps data in memory

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

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

    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.
