How to set the font of label in ColumnChart correctly?

Question

hello, everybody
By flex sdk 4.1.0, 4.5.1,
the same source but two effects of font of label of ColumnChart will be displayed.
.mxml:
<!-- mxml start -->
<?xml version="1.0" encoding="utf-8"?>

        <mx:verticalAxis>
            <mx:LinearAxis id="linearAxis"

            <mx:AxisRenderer id="horizonLabel" labelRotation="45" axis="{ch01_a2}" showLine="true" showLabels="true" styleName="myAxisStyle3">

            </mx:AxisRenderer>
        </mx:horizontalAxisRenderers>
        <mx:horizontalAxis>
            <mx:CategoryAxis id="ch01_a2"
                             dataProvider="{mainChart}"
                             title="Period"
                             categoryField="Period"
                             />               
        </mx:horizontalAxis>
    </mx:ColumnChart>
</s:BorderContainer>
<!-- mxml end -->
.css
<!-- css start -->
.myAxisStyle1 {
    placement:bottom;
    minorTickPlacement:none;
    tickLength:5;
    tickPlacement:none;
    color:#FFFFFF;
    verticalAxisTitleAlignment:vertical;
    fontFamily: Arial_AFE;
.myAxisStyle3 {
    placement:bottom;
    minorTickPlacement:inside;
    tickLength:5;
    tickPlacement:inside;
    color:#FFFFFF;
    fontFamily: Arial_AFE;
@font-face {
    src:url("font/arial.ttf");
    fontFamily: Arial_AFE;
    embedAsCFF: false;
<!-- css end -->
environment:
flex sdks->4.1.0
chart image:
the font looks like "Arial"
environment:
flex sdks->4.5.1
chart image:
the font looks like "Times New Roman"
Working at flex sdks 4.5.1,
the labelClass can be set to 'spark.components.Label'(defalut) or 'mx.controls.Label',
it seems that we can set labelClass to mx.controls.Label to get the same effect of font of label in ColumnChart when flex sdks->4.5.1
            <mx:AxisRenderer axis="{linearAxis}" showLine="true" showLabels="true" styleName="myAxisStyle1" labelClass="mx.controls.Label">
            <mx:AxisRenderer id="horizonLabel" labelRotation="45" axis="{ch01_a2}" showLine="true" showLabels="true" styleName="myAxisStyle3" labelClass="mx.controls.Label">
but it also causes a memory leak.
1) Can anyone tell me how to show the font of label of ColumnChart correctly (looks like "Arial") when using the labelClass 'spark.components.Label' ?
2) Can anyone tell me how to solve the memory leak when using the labelClass 'mx.controls.Label'?

Answer 1

Hi,
for combobox in a table (I assume the combobox is shown un column 2, thus the index 1)
oracle.jbo.uicli.jui.JUTableLOVEditor lovCellEditor = (oracle.jbo.uicli.jui.JUTableLOVEditor) jTable1.getColumnModel().getColumn(1).getCellEditor();
lovCellEditor.getComponent().setFont(new Font("Arial",Font.BOLD,13));
For the LOV panel this is a bit more complicated because you need to create a custom LOV panel as described in http://www.oracle.com/technology/products/jdev/howtos/10g/jclientlov/customadfjclientlovpanel.html
I filed a bug today to expose the component on a LOV to public so they can be modified
