there's a bug in the following method (in listeners.js):
the corrected version is:
DynObject.prototype.addEventListener=function(listener) {
if(!this.eventListeners) {
this.eventListeners = [];
}
// the following line has been moved
// it was inside the if-statement
this.hasEventListeners = true;
for (var i in this.eventListeners) if (this.eventListeners[i]==listener)
return;
this.eventListeners[this.eventListeners.length]=listener;
}
the line:
this.hasEventListeners = true;
has to be moved outside the if-statement.
otherwise the following happens: if you add some listeners and then remove
them all, this.hasEventListeners is set to false, but if you decide to again
add a listener, hasEventListeners would remain false, because eventListeners
is defined and the if-statement is not executed.
