CF10: cfchart in a gateway giving: java.lang.NullPointerException

We have recently upgraded to CF10.

Our application uses cfchart for reports.

In a standard request the charts work perfectly. We create png images en the publish them. All server activit

<cfchart name="cfChartData" format="png" chartWidth="650" chartHeight="200" rotated="yes" show3d="false" >

                    <cfchartdata item="item 1" value="20">   

                    <cfchartdata item="item 2" value="50">   

                    <cfchartdata item="item 3" value="10">   

                    <cfchartdata item="item 4" value="35">                           

</cfchart>  

When I try to use this through a gateway (cfml type) is returns the folowing exception:

"Error","Thread-22","08/21/13","14:13:36",,"Error invoking CFC for gateway netqromeventgateway: null  {GATEWAYTYPE={CFMLGateway},ORIGINATORID={CFMLGateway},DATA={{ACTION={testChart}}},GATEWAYID={netqromeventgateway}}."
