use expressions in iReport fields

[Javix]

I use iReport 2.0.2 an an XML data source for my report.

 

Why is it not possible (it doesn't work anyway) to use an expression like:

Code:

$F{receiverStreet} + " " + ($F{receiverHouseBox}.equals(""«»)? "" : $F{receiverHouseBox})

in a textfield?

If in my xml-file receiverHouseBox(String) value is null or equals a "", so the line is empty evenn if there is a receiverStreet value.

Can anybody to explain me that? Thanks.

can you maybe post the error that sends you or a better description. First make sure that all Fields are the same type if not Cast them.

I found a solution. You should do like this:

Code:

$F{receiverStreet} + " " + ($F{receiverHouseBox}!=null? $F{receiverHouseBox}:""«»)
