<p>I'm running Eclipse Luna and BIrt 4.4</p>
<p>In the Eclipse IDE, i have a report. i'm viewing it in the Report Design perspective.</p>
<p>The report was a working report before i upgraded eclipse and BIRT.</p>
<p>i Test the connection to the data source (postgres) and it succeeds.</p>
<p>I dobleclick on the dataset and it opens the window showing me the query</p>
<p>I click on Output Colums and i get java.lang.NullPointerException.</p>
<p>The details are shown below.</p>
<p>Any idea what has changed in 4.4 that is causing this problem to appear?</p>
<p>thanks</p>
<p> </p>
