   Hi,
   
   There is an issue with itemRenderer on DataGrid.
   
   The following code show empty cells (count cells is right but no text)
   
   ```
   <js:View xmlns:fx="http://ns.adobe.com/mxml/2009";

                        import org.apache.royale.collections.ArrayList;

                                mydg.dataProvider = arl;
                        }
   
                        private function ev_clic_ar_dp():void {
                                mydg.dataProvider = ar;
                        }
                        
                        private var ar:Array = ["Bob", "Joe", "Frank", "Sally"];
                        private var arl:ArrayList = new ArrayList 
([{label:'bob',value:'bob'},{label:'bob2',value:'bob2'},{label:'bob3',value:'bob3'}]);

   When debugging js the issue is on setting data on itemRenderer :
   
   (_DataItemRendererFactoryForArrayData.as_) function 
`dataProviderChangeHandler`
   ...
   _ir.data = dp[i];_  // dp = ArrayList with right datas
   jump to (_StringItemRenderer.as_)
   
   ```
   org.apache.royale.html.supportClasses.StringItemRenderer.prototype.set__data 
= function(value) {
     
org.apache.royale.html.supportClasses.StringItemRenderer.superClass_.set__data.apply(this,
 [ value] );
     this.text = this.dataToString(value);
   };
   ```
   
   **value** is undefined when enter function
