<p>Hi, </p>
<p> </p>
<p>Any idea when this exeption would happen. The following lines work fine in earlier iHub(3.*) version started failing in the latest iHub 16.0.1. It fails at the line marked in red.</p>
<p> </p>
<div>dataSetMetaHandle = reportContext.getDesignHandle().findDataSet("metaDataSet"); //Find Existing Data Set</div>
<div> </div>
<div>var myconfig = reportContext.getReportRunnable().getReportEngine().getConfig();</div>
<div>queryDefinition = new QueryDefinition( true );</div>
<div>queryDefinition.setDataSetName( dataSetMetaHandle.getName() );</div>
<div> </div>
<div>mySession = DataRequestSession.newSession(myconfig, new DataSessionContext(DataSessionContext.MODE_DIRECT_PRESENTATION));</div>
<div>mySession.defineDataSource(mySession.getModelAdaptor().adaptDataSource(dataSetMetaHandle.getDataSource()));</div>
<div>mySession.defineDataSet(mySession.getModelAdaptor().adaptDataSet(dataSetMetaHandle));</div>
<div> </div>
<div><span style="color:#ff0000;">var pq = mySession.prepare( queryDefinition );</span></div>
<div> </div>
<div> </div>
<div><span style="color:#000000;">This is the exception we see it in the server log:</span></div>
