solved
got working changing php, , setting rootvisible false on treepanel.
i changed tree store bit.
ext.define('sampletreedata', { extend: 'ext.data.treestore', autoload: false, autosync: false, proxy: { type: 'ajax', url : '', reader: { type: 'json', root: '' } }, root: { expanded: true }, getdata: function(callback, scope) { var store = this; store.proxy.url = 'data.php?mode=getdata'; store.load({ scope : scope, callback : function(records, operation, success) { if (ext.isfunction(callback)) { callback(store, scope, records, success); } } }); } }); <?php $data = '[{' . 'text: "tree root",' . 'expanded: true,' . 'children: [' . '{' . 'text: "fruits",' . 'children: [' . '{ leaf:true, text: "apple" },' . '{ leaf:true, text: "orange" }' . ']' . '},' . '{' . 'text: "vegetables",' . 'expanded: false,' . 'children: [' . '{ leaf:true, text: "carrot" },' . '{ leaf:true, text: "beet" }' . ']' . '},' . '{' . 'text: "dairy",' . 'children: [' . '{ leaf:true, text: "milk" },' . '{ leaf:true, text: "cheese" }' . ']' . '}' . ']' . '}]'; $logref = fopen('data.log', 'w'); fwrite($logref, "entered script.\n"); if(isset($_post['data'])){ fwrite($logref, "senddata\n"); return 'senddatasuccess'; }else { fwrite($logref, "getdata\n"); echo $data; } fclose($logref); ?>
