Thanks for remining this, but what about the new paradigm. Doing :
X= OpenLayers.Class({
initialize:function() { this._p= "A.initialize";
OpenLayers.Console.info(this._p); },
pa:"PA",
p_:null,
ma:function() { OpenLayers.Console.info("A.ma="+this.pa); }
});
X = X.prototype.initialize = function() { this.p_= "A.initialize-new";
OpenLayers.Console.info(this.p_); }
try {
var x1= new X();
OpenLayers.Console.assert((x1 instanceof X));
OpenLayers.Console.assert((x1.p_=="A.initialize-new"));
x1.ma();
} catch(ex) {
OpenLayers.Console.warn(ex);
}
gives :
TypeError: x1.ma is not a function
It does not although work with 2.10 (same exception).
Did I miss something ?
