t:dataList seemed to behave the same way. I did a little more experimenting
and I can print out the title of the charts returned by the iterator or
dataList, so they aren't null. The chart tag just thinks the object is
null. I get this error.
javax.faces.el.PropertyNotFoundException: Error setting property 'component'
in bean of type null
caused by
<tr:chart value="#{opticChart}" binding="#{opticChart.component}"
if I take out "binding="#{opticChart.component}"" I get a null pointer
exception when it tries to call getXValues on the chart object.
Here's the code again:
If I comment out the tr:chart tag the title of all charts in the array are
correctly displayed. The chart tag is getting a null chart object for some
reason.
<t:dataList var="chart" value="#{displayBean.summaryCharts}">
<tr:outputText value="#{chart.title}"/>
<tr:chart value="#{chart}"
XMajorGridLineCount="6" YMajorGridLineCount="6"
inlineStyle="width:200px; height:200px; background-color:white;"
gradientsUsed="false"
legendPosition="none" perspective="false" type="verticalBar"
animationDuration="0"
rendered="true" templateSource="/styles/TrinidadChartTemplate.svg">
</tr:chart>
</t:dataList>
