You will need to show us what you have done. I suspect you are doing something like below.....

myString!=null

This will result in a boolean. Or maybe you are using a function that results in a boolean.
To get round this, you need to know what you want to do if the variable is null and if it isn't. You can use an inline IF to deal with this like below....

myString!=null ? myString : "myString is null"

The above says "If myString is not null, then use the value held by myString. Otherwise use 'myString is null'"

Hi
Take a look at tfilterRow component, you can filter the rows with component.
