views_handler_filter_null() not working

Greetings,

I (and others, I'm sure) need to be able to create a view based on whether a given field has something in it and IS/IS NOT NULL is just the thing for it. Bug is, while there is a views_handler_filter_null function, there is no option for is or isn't null when adding my field to Filters. I've dug around in the views module code, but I can't figure out where the filter options are coming from. I've also tried to fake it using wildcard characters with some of the options that are there (Is Equal To, Contains, Contains Any Word, Contains All Words, Starts With, Ends With, Does Not Contain), but that doesn't work for me either. And so I'm reduced to a bug report, because this functionality is just way too useful to not have.

Thanks!

salud,
Bill
