    When I go to Go >> New Report in the server, and create a new report all the way to step 4, I get the NullPointer exception below. I also get a message that says: 14:38:19,812 ERROR [AdhocWebService] Failed to generate the report preview. Please check the server log for details of the error. Which is interesting, because the preview of the report does show up in my browser... The steps I used to reproduce this are: 1. Start WAQR by hitting Go >> New Report in the server 2. Choose Orders in the Business Model section, hit Next 3. Pick a bunch of random items top show in each section of the report, hit Next twice 4. Hit the Go button to show the preview Here's the exception: java.lang.NullPointerException at org.pentaho.core.solution.SimpleOutputHandler.setOutput(Unknown Source) at
