Can you simply just add new bands to your report?

 

If so - how do you do this?

[Can we concat $F{Field} into $V{Variable}?]

Hi,

 

I had a quick look at your report. There were quite a few errors in your XPaths, when selecting an attribute you must have a slash before the @ symbol:

 

e.g.

 

BookingReferenceID@ID

 

should be

 

BookingReferenceID/@ID

 

When I corrected these mistakes the text field $V{VINV} displayed just fine.

 

Actually, you do not really need a variable for this expression, you can place the expression:

 

$F{SINVOICENUMBER}.equals($F{INVOICENUMBER}) ? "ciao" : "NO"

 

directly into the expression for the text field.

 

Regards,

Colin E.

I have created an XY plot with asingle series, with the following values:

So ... what am I doing wrong?
