How concatenate String in Variable Expression??

Hello,

I've some problem to concatenate a String!

I have just concatenate a Double fieldand all works. But with String it doesn't works.

I have a DetailHotel band where there is the field $F{SINVOICENUMBER} that appear correctly, in the hoteldetail band when I create the pdf.

Then, I have created a variable "VINV" that has this expression :

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

and I've put this variable on the Summary band.

When I export the pdf, the value of this variable is always "null". I don't understand why?

In my variable, I have set:

Variable.Class type=String

Reset Type=Report

Calculation type=nothing

Increment Type=None

Where I wrong??

As you'll note seeing the other variables, I've just sum the double value correctly!

I send the Fattura.jrxml, xml data source and the pdf result, in the zip file.

Thanks in advance,

Francesco
