I have a textfield expression which is a combination of two fields. Say number and name. Now I want "number" to be blank when it is null. So I added this attribute to my textField tag. However I still get "null" when number is null.

 

My expression is -

<textFieldExpression class="java.lang.String"> $F{number} + " " + $F{streetnum}</textFieldExpression>

 

How can I get this to print blank when number is null?

 

TIA,

- Manish

assuming number is an object and that you mean "if number is null, print an empty string", how about:

 

<textFieldExpression class="java.lang.String">

$F{number} + " == null ? "" : " +$F{Number} + " " + $F{streetnum}

</textFieldExpression>
