2006 IR Open Dicussion Posted August 26, 2006 Share Posted August 26, 2006 By: Phil - pchar 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($F{OPHONE}.TRUE)]]></printWhenExpression> but iReport complains with net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: 1. TRUE cannot be resolved or is not a field value = (java.lang.Boolean)(new Boolean(((java.lang.String)field_OPHONE.getValue()).TRUE)); Any help appreciated. Thanks! Phil By: Johnny A - sykosity RE: Hiding a field if no data in database 2006-01-19 15:58 What is with the TRUE that you have in your expression? new Boolean($F{OPHONE}.TRUE) ?? $F{OPHONE} is a String from what I can tell, why not try something like: new Boolean($F{OPHONE} == null) By: Johnny A - sykosity RE: Hiding a field if no data in database 2006-01-19 16:04 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 Link to comment Share on other sites More sharing options...
