Scripted Data Set row not getting filled

apollowong

<p>I have created a BIRT report using scripted dataset to get data from a java class. The code seems to be able to get results but nomatter what I do I cannot get the dataset row to be filled. Here is my open script in dataset:</p><p> </p><p>open:</p><div>importPackage(Packages..javalib);</div><div> </div><div>data=new Data_ImpType();</div><div> </div><div>ev=data.GetSomething();</div><div> </div><div>and my fetch:</div><div> </div><div><div>row["EV01"]=ev[19];</div><div>row["EV02"]=ev[18];</div><div>row["EV03"]=ev[17];</div><div>row["EV04"]=ev[16];</div><div>row["EV05"]=ev[15];</div><div> </div><div>return(false);</div><div> </div><div>where the "EV01"... are the name of the column in my dataset. I can actually print out the contents of ev[] after the fetch, but the dataset table remains empty. </div><div> </div><div>BIRT did not complain about any error in the javascript. Would someone help....? Thanks ahead.</div><div> </div><div> </div></div><div> </div>

<p>Fetch should look something more like:</p><p> </p><p>Fetch:</p><pre class="_prettyXprint">if (ev != null){   row["EV01"]=ev[19];   row["EV02"]=ev[18];   row["EV03"]=ev[17];   row["EV04"]=ev[16];   row["EV05"]=ev[15];   return (true);}return (false);</pre><p>The fetch method has to return true if there is data, and false if there is nothing to return. In your case, your always forcing it to false, so BIRT doesn't think there is anything there.</p>
