Textfield pattern like "("+$P{myField}+")"

Hi,

What's the most elegant syntax for Textfield to print a String value between parenthesis and just blank when the value is null ?

 

I don't want to write this Textfield expression all over the place:

( $P{nom} != null && $P{nom}.length() > 0 ? "(" + $P{nom} + ")" : null )

 

PS: I don't want to preprocess my parameters before feeding them to Jasper

 

PPS: "Blank when null" works great for Date and number fields with a pattern but I understand there is no such thing for plain String.

 

Thanks a lot and congratulations on this great tool.

I don't know the syntax off hand, but I bet you could set a boolean and then use that in your string printWhenExpression's expression.

 

I think. :-)
