Justin Mclean updated FLEX-17760: --------------------------------- Labels: easy test (was: ) > datagrid datatip "[object Object]" for null/unset items > ------------------------------------------------------- > > Key: FLEX-17760 > URL: https://issues.apache.org/jira/browse/FLEX-17760 > Project: Apache Flex > Issue Type: Bug > Components: mx: DataGrid > Affects Versions: Adobe Flex SDK 3.0 (Release) > Environment: Affected OS(s): All OS Platforms > Language Found: English > Reporter: Adobe JIRA > Labels: easy, test > > Steps to reproduce: > 1. DataGrid with dataProvider where some column properties are null or unset > 2. set showDataTips="true" for that column > *see example code below* > Actual Results: datatip "[object Object]" on those fields > Expected Results: no datatip (like for "" fields) or empty datatip when a > property is null or unset. > The bug occurs with both Flex 2.0.1 and Flex 3.0 SDK. > Explicitly setting dataTipField does not change it and a label function would > be provided the entire row data without being passed the dataField. > Workaround: as an object result of a http service contains null properties > for emty nodes/attributes one must > either manually replace null with "" in the data or use a custom item > renderer (e.g. based upon a Label). > Supposed Reason: > DataGridColumn.itemToDataTip gets passed the row data; when the > (data(tip))field is null or unset > data[field] != null is false and data = data[field] is not executed, thus > data.toString() is performed on the row data. > There should be a check somewhere to show no datatip at all in this case. > Example code: > <?xml version="1.0" encoding="utf-8"?> > <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"> > <mx:Script> > <![CDATA[ > private const gridData: Array = [ > { desc: "with item set.", item: "hello" }, > { desc: "with empty string", item: "" }, > { desc: "with null item", item: null }, > { desc: "without item property" } > ]; > ]] > > > </mx:Script> > <!-- expected behavior: no datatip when datatip field is null or unset --> > <!-- actual datatip for null and unset properties: "[object Object]" --> > <mx:DataGrid dataProvider="{gridData}"> > <mx:columns> > <mx:DataGridColumn dataField="desc" headerText="Description" > showDataTips="true"/> > <mx:DataGridColumn dataField="item" headerText="Item+Datatip" > showDataTips="true"/> > <mx:DataGridColumn dataField="item" dataTipField="item" > headerText="+dataTipField" showDataTips="true"/> > </mx:columns> > </mx:DataGrid> > </mx:Application> > -- This message is automatically generated by JIRA.
