Refresh grid at startup

[Spiff1]

Hello,
i have a grid in a window in a tab.
When i activate the tab i can see the window with the grid inside. But no data.

Something like:

myTabs.on('activate', function(panel)
{
   if (panel is your gridpanel, or contains your grid)
      panel.getStore().load(); //or other appropriate store load method.
}
);
