Spark DataGrid Issue

Question

I'm working with the new Spark DataGrid, and I understand it's still a work in progress. I've also created a bug in the Adobe bug system. However, I want to be sure that I'm not overlooking something.
Here is an example that illustrates the issue. If I create an itemRenderer for a column in a dDtaGrid, it takes 2 clicks to trigger the click event and 3 clicks to trigger the doubleClick event, if you click on the column with the itemRenderer. This happens about 95% of the time. Occasionally, it works as expected, but that's a rarity. So the question is, am I doing something wrong in the use of itemRenderers.

Answer 1

I have approximately the same problem : I want to listen double click (doubleClick or gridDoubleClick) on a spark datagrid.
The double click event is always dispatched when I double-click on a column whose item renderer is a textArea (even with doubleClickEnabled=false).
The double click event is SOMETIMES dispatched when I double-click on a column whose item renderer is an image or a label :
1. When I double-click for the first time on the label renderer : it gives focus to datagrid and select item but does not dispatch doubleClick
2. When I double-click on the textArea colum, then on the Label column of the same row, doubleClick is well dispatched
3. When I double-click on the textArea colum, then on the Label column of a different row, doubleClick is not dispatched
4. when I double-click on the label column after double-clicking on another row in the Label column, doubleClick is well dispatched
I think it's the same behaviour with simple click event.
Do you think spark datagrid is not stable enough and we should use mx datagrid instead ?
Here is the code :
<s:DataGrid dataProvider="{arrayCollection}" doubleClickEnabled="true" doubleClick="trace(event)" gridDoubleClick="trace(event)">
        <s:columns>
            <s:ArrayList>
                <s:GridColumn>
                    <s:itemRenderer>
                        <fx:Component>
                            <s:GridItemRenderer>
                                <s:Label text="{data.label}"/>
                            </s:GridItemRenderer>
                        </fx:Component>
                    </s:itemRenderer>
                </s:GridColumn>
                <s:GridColumn>
                    <s:itemRenderer>
                        <fx:Component>
                            <s:GridItemRenderer>
                                <s:TextArea text="{data.label}"/>
                            </s:GridItemRenderer>
                        </fx:Component>
                    </s:itemRenderer>
                </s:GridColumn>
            </s:ArrayList>
        </s:columns>
    </s:DataGrid>
