Empty string becomes null on submit

[Inge Solvoll <in...@gmail.com>]

I've suddenly gotten a problem in my code. When I enter nothing into a text
field on a tapestry page and submit, the corresponding abstract getter
method returns null instead of empty string "". I have checked my code, and
nothing has changed, this used to work before. I haven't upgraded any of the
jar files for tapestry or tacos or something like that.

One thing has changed: I've started using UTF-8 encoding for my webapp. I
have a filter that enforces characterEncoding UTF-8, and my html and
.application file are also configured to use UTF-8. I'm suspecting the
Unicode changes to cause this strange null-behaviour, but I don't know what
to do. I've tried rolling back to ISO-8859-1 like before, but nothing
happens. Don't know if I managed to remove all UTF-8 references completely
though.

Has anyone experienced something similar? Is this an encoding issue or is it
something else?

Actually, I didn't expect this behaviour. And I'm pretty sure it worked a
couple of months ago. It seems perfectly natural to me that an empty string
submitted from the user should actually become an empty string in java.

afaik this is the normal behaviour: empty fields set the property to null.
