Hiding a field if no data in database

2006-01-19 07:16

Hello,

 

I would like to hide a label on the report if a field in the datasource is blank. I have tried <printWhenExpression><![CDATA[new Boolean($F{OPHONE}.TRUE)]]></printWhenExpression> but iReport complains with net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: 1. TRUE cannot be resolved or is not a field value = (java.lang.Boolean)(new Boolean(((java.lang.String)field_OPHONE.getValue()).TRUE));

 

Any help appreciated.

 

Thanks!

 

Phil

What is with the TRUE that you have in your expression?

 

new Boolean($F{OPHONE}.TRUE) ??

 

 

$F{OPHONE} is a String from what I can tell, why not try something like:

 

new Boolean($F{OPHONE} == null)

These might be some alternative expressions which might help your cause:

 

Print When String is not null:

new Boolean( $F{OPHONE} != null )

 

Print When String is not blank:

new Boolean( !($F{OPHONE}.equals("")) )

 

hope that helps
