Number of Layer Features

Tamas,

I'm using the following:

for (int i = 0; i < map.numlayers; i++)
{
	layerObj Layer = map.getLayer(i);
	numFeatures = Layer.numitems;
}

Like I have said, numFeatures always returns zero.
As you can see, I don't call the Layer.Open(); method. At this example, is
it necessary ?
When execute "layerObj Layer = map.getLayer(i);" the method "Open()" is not
internally called ?

Thank's again,

Fabio

Have you called layerObj.open() ?

Best regards,
