How to rerender a tree node in rich faces
Hi
I would like to re-render a node in a richfaces tree rather than rendering the whole tree, through my backing bean.
I tried to do it as mentioned below.
AjaxContext ajaxCtx = AjaxContext.getCurrentInstance();
ajaxCtx.addComponentToAjaxRender(selTreeNode);
// selTreeNode is the UITreeNode component of selected tree node, which
// I want to render
But while rendering the tree I got the following exception in the browser.
