[OpenLayers-Users] Trouble with accessing vector/WFS layer features

[Ivan Grcic]

Well,

layer.refresh({force:true}) wont do because this method is checking
layer visibility

    refresh: function(obj) {
        if(this.calculateInRange() && this.visibility) {
            this.events.triggerEvent("refresh", obj);
        }
    },


but I think calling trigger read on BBOX strategy should do:

layer.strategies[0].triggerRead()

Cheers
