primefaces CHARTS with JSF librairies

[squareman]

Hello everybody,

I try to get chart viewing from a bean using icefaces and Prime faces taglibs:

xmlns:p="http://primefaces.prime.com.tr/ui"



<p:lineChart value="#{tabset.metrics}"
var="statData" xfield="#{statData.dateTime}" >
<p:chartSeries label="firstData" value="#{statData.firstData}" />
</p:lineChart>

I've got the following error and I don't know why because my bean has got values (step debugging on TOMCAT server) :

java.lang.NullPointerException

Any ideas ?

It's quite urgent.

Thanks in advance

Hi, can you also provide the source code of your backing bean: "tabset" so I can see how you create your data.
