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

[Mikael C. <mik...@cl...>]

Hi guys,

I'm looking at your mails right now, it reminded me I had some work on WFS
protocol I hadn't pushed. I'm afraid we're stepping on each other's toes, so
please hold on while I look at it and I'll get back to you soon.
