Hmm - I can notice problem but only on acceptance (processing) of an 
already submitted request. Can you describe how you got the error upon 
submission? From your description it seems that you was able both to get 
this upon submission and when processing the request.

Seems we will have to re-think support for 0-length values. It makes 
little sense in practice but lot of troubles as missing value and 
0-length value are "hard" to distinguish.

I've opened a ticket to cover this. Won't make it for the upcoming 
2.5.0, but at least the error message upon accepting the request was 
improved so you get the name of the problematic attribute (and so you 
can ignore it).

Cheers,
