<p>Hello,</p>
<p>I have developped some reports with Birt (Windows Seven - Eclipse Mars - BIRT 4.4.0).</p>
<p>They are working well.</p>
<p> </p>
<div>I got a new PC at work with the same programs versions.</div>
<div>My reports don't works on this new computer.</div>
<div> </div>
<div>I made tests with a new simple report (one data set row) : it works.</div>
<div>If I add a Cascading Parameter Group, I had this error when I ask a "View Report" :</div>
<div><br><blockquote class="ipsBlockquote">
<div>HTTP ERROR: 500</div>
<div>Problem accessing /viewer/preview. Reason:</div>
<div> </div>
<div>Server Error</div>
<p> </p>
</blockquote>
<p> </p>
</div>
<div>What can I check ?</div>
<div>Can you help me ?</div>
<div>Thanks</div>
