Nested list components

[bloomper]

Hi!

Is it correct that nested list components are not supported?

When trying to do this, I get the following exception:

java.lang.NullPointerException
     at net.sf.jasperreports.engine.JRExpressionCollector.getDatasetCollector(JRExpressionCollector.java:284)
     ....

iReport does not seem to handle this as well as the nested list component is blank although it does contain elements.

I need to visualize the following data in a tabular manner:

    <Activity>
      <Engagement>
        <Year>2010</Year>
        ...
      </Engagement>
      <Functions>
        <Function>
          <Name>Test</Name>
          <SubFunctions>
            <SubFunction>
              ...
            </SubFunctions>
          </SubFunctions>
        </Function>
      </Functions>
    </Activity>

I do understand that subreports might be a better choice but the list component is so much easier to work with.

Cheers,
Anders

Indeed, that doesn't work at the moment.  Log a bug for it and we'll try to come up with a solution.

I'm not 100% sure when the functionality was added but I just made a report in JR 5.0 that has nested list elements! Good stuff
