I am trying out the custom report item mentioned at below link:<br />

<br />
But when I create a sample report containing the custom report item and run the report, I get this exception [1]<br />
<br />
I tried searching mailing list, and see that few have raised the same issue previously but without any resolution.<br />
I am using birt-report-designer-all-in-one-2_3_2_1.zip.<br />
