Re: [Gwt-openlayers-devl] WFSprotocol and Vector Layer

Hi Edwin,

No problem, it's my fault, it will teach me to push my commits on time !
I think I didn't break any of your code, but maybe you'll want to check.

BTW Poul, from my tests I have come to the conclusion that OL doesn't work
well with WFS v1.1, so I used v1.0. Maybe you should try that.
