Re: [Portugal] Não consigo visualizar as layers WFS...

Fri Jun 11 05:55:33 EDT 2010

Olá bom dia,

Também estou a iniciar-me no Geoserver (há cerca de uma semana) e tenho este mesmo problema do Oscar. 

Fazendo a edição com o uDig via WFS-T, tudo corre bem, consigo ver o resultado da edição, tanto na base de dados, como no QGIS, mal faço "Commit changes" no uDig. 

No entanto, utilizando o exemplo wfs-t.html, mesmo com as alterações da bbox que resolveram o problema ao Oscar, não consigo visualizar o WFS. Aliás, com os as alterações do Oscar, nem aparecem os WMS, nem sequer os controlos do OpenLayers. 

Deixo aqui o código que estou a testar:
