Null Pointer on '...hasNextChild'

newbie321

<p>Hi, </p>
<p> </p>
<p>I have a report that uses dataset POJO and because of all the reasons (birt/eclipse bugs) I cann't really update the pojo dataset once it is created.  The workaround that I found is to go straight into the XML representation of the .rptdesign and edit it manually.  This method worked very good and like a charm for me until I hit the following error on one of my reports:  </p>

<p>Anyone knows what 'hasNextChild' could possibly mean in this case? </p>
<p>I did the sample POC report by editing xml directly adding the same mappings and it works without a glitch.  The moment I put identical mappings into the real report, I hit the error above. </p>
<p> </p>
<p>I am adding mappings into the following sections:</p>
<p>1) columnHints</p>
<p>2) cachedMetaData</p>
<p>3) dataSource</p>
<p>4) queryText </p>
<p> </p>
<p>Are there any other sections in xml that I would normally need to modify in my xml code?</p>
<p> </p>
<p>I am sorry my questions is somewhat abstract as I am not providing the report design itself (it is complex and works only with a database we have).  </p>
<p> </p>
<p>Thanks for your help!! </p>
