birt ChartException caused by java.lang.NullPointerException - charts

Question

I have birt report deployed to our server. I am getting the exception mentioned above on some pages but not all. I figured null means maybe there's no data but I made sure and checked triple times that there is. What must be causing this error? Any idea?
Here is the stack trace.
The following items have errors:
Chart (id = 706):
-
null ( 1 time(s) )

here is an excerpt from the birt error log I got from test server. I noticed though that it started acting like that when I added this script (I already added null checker, just incase it was the cause)
function beforeDrawDataPointLabel( dph, label, icsc )
{
seriesVal = dph.getSeriesValue()
insetLabel = label.getInsets();
if(seriesVal=="Opening Assessment")
{
if(insetLabel!=null)
{
insetLabel.setTop(0)
insetLabel.setBottom(0)
insetLabel.setLeft(0)
insetLabel.setRight(0)
}
}
else if (seriesVal=="Last Assessment")
{
if(insetLabel!=null)
{
insetLabel.setTop(0)
insetLabel.setBottom(0)
insetLabel.setLeft(0)
insetLabel.setRight(0)
}
}
if(label!=null)
label.setInsets(insetLabel)
//4 is NA while 5 is 0, this is a workaround for the labels to come up in the chart. zero val does not show labels/bar
if(dph.getOrthogonalValue()!=null || dph.getOrthogonalValue()!='')
{
if( dph.getOrthogonalValue() == 4 ){
if(label!=null){
label.getCaption().setValue("N/A");
label.setVisible(true);
}
}
else if(dph.getOrthogonalValue() == 5 ){
if(label!=null)
{
label.getCaption().setValue("0");
label.setVisible(true);
}
} else{
label.setVisible(false);
}
}
}
error log: (not very helpful for me.)

Answer 1

I was able to solve this by removing a line from my script. Apparently, the label.setVisible(true) or false was causing this error. Since I still need to hide the label, I just created a workaround and set the caption value to "" instead. Code is
label.getCaption().setValue("");
Btw, can anyone tell me why the label.setVisible() was making the error? I am confused. Most of the tutorial I read were coded like that, even on the sample documentation.
