Grid inside HTML form triggers submit on dialog buttons

[OysteinKrag]

If the grid is put inside a HTML form, the "OK" and "Cancel" buttons etc inside the dialogs (Hide Columns, Filter, Freeze columns) forces a post of the form. These buttons are type="submit" and should have been type="button". I fixed this temporarily by a 500ms timer setting the onClick="return false;" for all Sigma.grid buttons.

Could you please fix this?

My workaround:

    window.setInterval('fixGridButtons()', 500);      function fixGridButtons() {          var buttons = document.getElementsByTagName("button");         for (var i = 0; i < buttons.length; i++) {             if (buttons[i].className == "gt-input-button") {                 buttons[i].onclick = function() { return false; };                 grid = document.getElementById(grid_demo_id);                             }         }
