Need help with PRINT EXPRESSION

[jkeri]

I am not a Java developer so I dont know the java well enough.

 

My question is. I want to print a value of 'YES' when $F{NAME} is null and 'NO' when it is not null.

Try this in your textFieldExpression, wherever you want to display that YES/NO

<textFieldExpression><![CDATA[iF($F{FNAME} == NULL, "YES","NO")]]></textFieldExpression>

 

Simple conditional, displays YES or NO depending on whether or not FNAME is null. The IF conditional works as follows: IF(testExpression, true, false)

One more thing to add to the poster above is that NULL string is different from "" string which is an empty string. Make sure you actually do have nulls when testing that.
