Because Byte is a class and not a primitive type, you have to test it like this:

 

! new Byte( 0 ).equals( $F{ MyField } )

 

Note that placement of the constant value (new Byte( 0 )) to the left of the equals. This prevents null pointer exceptions if MyField does not get assigned properly.

Glad to help. iReport and Java require a slightly different way of thinking. Once you get there, you realize the great power of both... :)
