[OpenLayers-Users] WFS + Filter

[Andreas Hocevar]

Hi,

Please use Layer.Vector with a BBOX strategy and a WFS protocol instead 
of Layer.WMS and see if it works then. Also double-check if your Point_1 
is in the viewport, otherwise it won't be loaded because your custom 
filter is combined with a BBOX filter for the viewport.

Regards,
Andreas.
