[OpenLayers-Users] Getting all points for a geom?

[Adorian Ardelean]

Hi Guillermo,

I have not tried it with a WFS layer, but I think it should work (I infer by
looking at other examples on this list).
You may add the control when you initialize the rest of other controls you
use. The "..." stands for other controls :-)

I think you have to create the layer before you create the controls for it.
Just follow regular init() code as in other OL examples. Then when you want
to get a feature info you may use some code to activate the featureinfocontrol
(by click on a form entity, or image etc. associated with a "toggle"
function).

All the best,
Adorian
