.getExpressionValue("row[CUSTOMERNAME]" returns a NULL ! WHY? [message #992024]

Hi all,

I'm trying to count the CUSTOMER which name includes "Mini" so
I ' ve created a Table with the data item and coded:

onCreate :

row = this.getRowData();
CustName = row.getExpressionValue("row[CUSTOMERNAME]");
if( CustName.indexOf("Mini") = -1)
	count0Minis += 1;

And this is the Error Code:

The following items have errors:

Data (id = 110):
+ There are errors evaluating script "row = this.getRowData();

CustName = row.getExpressionValue("row[CUSTOMERNAME]");

if( CustName.indexOf("Mini") = -1)
count0Minis += 1;":

TypeError: Cannot call method "indexOf" of null (/report/body/table[@id="93"]/detail/row[@id="98"]/cell[@id="99"]/data[@id="110"]/method[@name="onCreate"]#6) (Element ID:110)

Why do I get a NULL as a return value if I use row.getExpressionValue??

Thanks,
Samet

Try:
this.getRowData().getColumnValue("CUSTOMERNAME");
BTW you know this can be done with an aggregation element that contains a filter expression. No code required.

Hey Jason,

Unfortunately I still get an error.
Thank you for the information to do it with an aggregation but I'm just trying to figure out how to work with BIRT.

Regards,
Samet
