[OpenLayers-Users] OpenLayers.Projection(OpenLayers.Util.getElement(......).value) - jQuery problem

[Noli Sicad]

Thanks Nick for this info.

Now, I have to replace $ into $j,

var $j = jQuery.noConflict();

I will try this option and see what happen.

Now, how extended the use of prototype in OpenLayers?

Is only Util.js uses prototype.js in OpenLayers?

I saw OpenLayers.mobile.js uses as well Prototype.
