#3389: Vector.getFeatureBy returns nothing, while firebug shows the data

I created an in-memory layer, with a single vector (a point) , basically
an entire sample off site:
var vector = new OpenLayers.Layer.Vector("testvectorlaag");
var point = new OpenLayers.Geometry.Point(-72, 42);
var feature_point = new OpenLayers.Feature.Vector(point,
{loc_code:'AA0123456789'});
vector.addFeatures([feature_point]);
map.addLayer(vector);
Now I made a second function to search for that specific point, using the
getFeatureBy function:
var feature = layer.getFeatureBy('loc_code', 'AA0123456789');
It always returns null.
I believe it's because of this line, line 843 in
OpenLayers/Layer/Vector.js:
if(this.features[i][property] == value) {
"this.features[i][property]" returns undefined with firebug, whereas my
watch shows everything filled.
I still see the same code in 2.11 RC1, so I'm thinking it works the same
there. (not tested though)
Also, I would expect to be able to use getFeaturesBy to get an array of
features. For instance, I would like to use that function to get all
features with some field set to some value to select/highlight them. The
current getFeatureBy only returns the first found feature.
