Re: [Gwt-openlayers-devl] gwt-openlayers

Hi Robert,

The WFS functionality is a recent contribution by Dave, maybe he
recognizes the problem easily. I still need to get working on a Java
port of the Open Proxy that is necessary for the WFS functionality and
that is included in the OpenLayers examples.

How are you running your code? Is the Python Open Proxy implementation up?

The dev list is not publicly visible as far as I am aware, but I have
cc'd this reply to the devl list.

Greetings,
Edwin
