I have a tabPanel which is reRendered via ajaxSupport of another component.
The problem is that in one of the tabs I have a huge data table which I dont want to reRender... but currently it is whenever I rerender the parent tab panel.
Is there a way to exclude children from rerendering when rerendering the parent ?
No. Specifying the component as reREndered - you mark it with all its childs.
As workaround - you may reRender concrete components inside tabPanel.
