[Portugal] Erro ao ler WFS gerado no Geoserver 2.0.2 no OpenLayers 2.10

[Jorge de Jesus]

O OpenLayers.ProxyHost so tem de ser configurado se estas a aceder a um
a web service que esteja num outro server quando tens tudo em localhost
nao necessitas de Proxyhost

Nao  sei que a ponto estao habituados a fazer desenvolvimento em
Javascript mas aconselho a usar a extensao firebug to firefox

http://getfirebug.com/

dar uma vista de olhos aos tutoriais e depois usar o firebug para ver o
que o servidor esta a mandar e tb ver se existe algo dentro do var wfslayer

O openlayers costuma ter bugs um pouco estranhos mas o mailing list do
Openlayers eh do melhor :)
