How to stop null from showing up on the report

[justdk]

Hi

I have a problem some of my boxes contains 10 parameters, sometime some of the parameters may be null.
How do I stop them from showing null?

I have set blankWhenNull to true. But when I have multiple parameters in the same box it doesn’t seem to matter.

I have seen some use null!=$F{invoiceNumber} ? $F{invoiceNumber}  : " "

But when I have 10 parameters it’s going to be a lot of code.

Isn’t there a simple way to fix this?

when u are using all parameters in the same text field element, i don't think u have any other option. blankWhenNull works when the field itself returns null.

Other option is to use duplicate parameters, one to hold values and other to check for null and give an appropriate value.

could you show an example with duplicate values
