Scripted Data Source Not working

prashbn

Hi,
I am using a scripted data source to fetch data from some java objects. In the open event of the data set I am creating an instance of the service class and calling the method to fetch the data.

count=0;
loginModulesService = new Packages.UsageReportService();
loginModules = loginModulesService.getLoginsByModule();

In the fetch event I am iterating through the list and setting the values for each row.

if(count < loginModules.size()){
row["LoginType"] = loginModules.get(count).getModule();
row["LoginCount"] = loginModules.get(count).getCount();
count++;
return true;
}
return false;

In the preview results of the data set I am able to see the results but when I try and preview the report I get the following exception

I have turned on the java debugger and notice that the java method gets called and returns. I am unable to find out the cause for the exception.

Thanks,

You have some bad script somewhere else in your report, from the looks of it, it one of the beforeRender events.

The easiest way to find it is to go the the Outline view, and under scripts, look at all the items that have a beforeRender script, and fix it there. If your seeing a preview of data, its not in your scripted data set.
