    Default [CLOSED-874] Tree nested node.select() method fails when given node is first rendered

    [CLOSED-874] Tree nested node.select() method fails when given node is first rendered


    ExtJS: 3.2 final
    OS: Windows 7 Pro 64bit
    Browser: Firefox 3.2, Chrome 4, IE6

    When I create a tree and load the data with preloadChildren enabled I cannot use select() method on a node to ensure its selection if the node is nested. Using ensureVisible() does show the node, but calling select() has no effect.

    		<script type="text/javascript">
    		//<![CDATA[
    			Ext.onReady(function(){
    				// simple window to test
    				new Ext.tree.TreePanel({
    					applyTo	: Ext.getBody(),
    					width	: 150,
    					height	: 200,
    					autoScroll: true,
    					loader	: new Ext.tree.TreeLoader({
    						preloadChildren: true
    					}),
    					root	: new Ext.tree.AsyncTreeNode({

    						children: [{

    							}]
    						}]
    					}),
    					rootVisible: false,

    								node.select();
    							});
    						}
    					}
    				});
    			});

    Default


    You need to set clearOnLoad: false on the tree loader. Otherwise the tree node reference gets overwritten during expandPath.

    Marking as closed.
