DVT : Gauge / Dial Set - ThresholdSet Causing Dials To Not Be Rendered

Question

Hi all,
Im using JDeveloper 11g, and I have a dial set which is currently just bound to some tabular data containing 6 rows. The dials display find without having any thresholdSet defined. However as soon as i try and add a threshold set as shown below, the dials no longer rendere when viewed at runtime. Is there some restriction to thresholdSets for dial sets? Or am i making an obvious mistake somewhere :p
<dvt:gauge id="gauge131" gaugeType="DIAL"
       imageFormat="FLASH"
       gaugeSetDirection="GSD_ACROSS"
       gaugeSetColumnCount="3"
       binding="#{backingBeanScope.backing_ExecutiveSnapshot.gauge131}"
       tabularData="#{backingBeanScope.backing_ExecutiveSnapshot.gaugeData}"
       dynamicResize="DYNAMIC_SIZE"
       visualEffects="AUTO"
       animationOnDataChange="ON"
       animationIndicators="ALL"
       animationOnDisplay="AUTO"
       inlineStyle="width:100%;height:400px;">
<dvt:gaugeBackground>
       <dvt:specialEffects fillType="FT_GRADIENT">
       <dvt:gradientStopStyle/>
       </dvt:specialEffects>
</dvt:gaugeBackground>
<dvt:thresholdSet>
       <dvt:threshold fillColor="#ff5a21" thresholdMaxValue="50.0" text="Low"/>
       <dvt:threshold thresholdMaxValue="100.0" fillColor="#00e700" text="High"/>
</dvt:thresholdSet>
<dvt:gaugeFrame/>
<dvt:indicator/>
<dvt:indicatorBase/>
<dvt:gaugePlotArea useThresholdFillColor="true"/>
<dvt:tickLabel/>
<dvt:tickMark/>
<dvt:topLabel/>
<dvt:bottomLabel/>
<dvt:gaugeLegendTitle text="Legend Title"/>
<dvt:gaugeLegendArea position="LAP_RIGHT"/>
<dvt:metricLabel position="LP_INSIDE_GAUGE"/>
</dvt:gauge>Thanks in advance...

Hi Branislav,
the code to populate the table is a shown below, taken from [this tutorial|http://download.oracle.com/docs/cd/E12839_01/web.1111/b31973/dv_gauge.htm#CDEDJDAF] and slightly modified
public List getGaugeData()
    ArrayList list = new ArrayList();
    String[] rowLabels  = new String[] {"London"};
    String[] colLabels  = new String[] {"Quota", "Sales", "Margin", "Costs", "Units"};
    double [] [] values = new double[][]{
        {60},
        {50},
        {13},
        {70},
        {11}
    for (int c = 0; c < colLabels.length; c++)
     for (int r = 0; r < rowLabels.length; r++)
        list.add (new Object [] {colLabels[c], rowLabels[r],
            new Double (values [c][r])});
    return list;
}I Add in the threshold by right clicking on dvt:thresholdSet in the 'structure' pane and selecting insert inside -> threshold. This allows me to add in one threshold value, but if i try and add further thresholds, in design view the dial compnent is replaced with a red 'x'
