I can't figure out how to set up a text input parameter to allow empty strings but not null values in BIRT 4.2. Apparently there used to be "allow null" and "allow blank" options, but if they still exist, they can't be set through the Eclipse GUI. (Well, either that, or they're hidden in some unbelievably asinine place, i.e. absolutely anywhere other than New/Edit Parameter window.) There's an "is required" checkbox, but that doesn't do what I want; it allows both null values and empty strings. I want to allow empty strings, but not null values. Is it still possible to do this, and if so, how?

The isRequired checkbox replaced the other two options. Take a look at
this bugzilla entry:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=252343
You could also put a validation script on the parameter with an
expression similar to :
if( params["NewParameter"].value == null ){
false;
}else{
true;
}
