hide if empty ignored?

The same thing is happening to me, in my case the view has an output format of "pdf_unformatted", and basically is that in version 7.x-1.7 the fields had the option enabled to be hidden if they had no value, but with the update to 7.x-3.1, this configuration is not working, because the fields that have no value (null or empty) are generated in the pdf, generating a blank space visually. Any suggestions?

Thanks, that's a bit more info.

I've looked at the code again, and I think I can see where a test for empty data got dropped in 7.3.

Please try the attached patch and let me know the result.
