Hi. When a tree node is selected, the rich:editor will display its content. However, using reRender attribute will make the tinyMCE refresh every time a tree node is clicked, which is not efficient and looks ugly. In an EXT JS-struts project, I can update the editor content:
Ext.Ajax.request({ url: "<%=contextPath%>/item.action", params: {dispatch:'getContent', sectionId:newSelectedNode.id, splId:root.id}, success: function(r) { document.itemForm.content.value = r.responseText; } });
