how to reload the Tree Component?

These are piecess jsp and javaScript Code.

<%@ taglib prefix="mvc" uri="http://www.ptc.com/windchill/taglib/jcaMvc"%><mvc:tableContainer compId="ext.reports.builder.TreeReport" height="500" /><script>     function submitParameters() {                    var params = { number : 'variable'   }; //pass new variable                    PTC.jca.table.Utils.reload('ext.reports.builder.TreeReport', params, true); //to reload the tree compoment and add  new variable.          }</script>

The  javascript   API  'PTC.jca.table.Utils.reload' throw exception  when the store be reloaded.

//the JS file path:D:\ptc\Windchill\codebase\netmarkets\javascript\util\windchill-all-debug.js
PTC.jca.table.Utils.reload = function(id,params,removeStaleData){     //SPR 2000225. The table data gets duplicated when delete an object from folders page.   if(removeStaleData === undefined){          removeStaleData = true;    }    var table = tableUtils.getTable(id);    if (table !== null) {        var selectedOnlyMenu = Ext.getCmp(PTC.jca.table.getWTablePanelID(table.id) + '.selectedOnlyViewItem');        if (selectedOnlyMenu && selectedOnlyMenu.checked === true) {            selectedOnlyMenu.setChecked(false);        }        table.getStore().load_complete= false;        table.getStore().totalLength = 0;        var form = PTC.jca.table.Utils.getTableFormData(table);        var formData = Ext.urlDecode(form);        formData.tableID = table.id;        formData.refreshTable = PTC.jca.table.Utils.getFormattedTableId(table.id);        Ext.apply(formData, params);        if (removeStaleData) {          table.store.removeAll();          jsca.unSelectHiddenCheckboxes(id);//Remove hidden checkboxes div if we are removing data from store        }        table.store.fireEvent('reload'); //PTC.jca.table.Utils.reloadLegacyTable<==the function to do refreshCurrentElement        table.store.on("exception", PTC.jca.table.Utils.reloadLegacyTable, null, {single:true});         table.store.reload({            params: formData,            reload: true        });    }}; 

I guess PTC.jca.table.Utils.reload is not support Tree table?  I have use this funciton to reload table compoment and run correct.

Actually this issue is not big problem,Browser just to request Windchill server twice.

I try to compare  first result page to  second result pages.They are the same but unique Key.
