Lunna,
I am the originator of the message, and I would like to thank you very much
for he fix. It seems to be working like a dream.
I suggest it is included in the next update of DynAPI, as it seems like
half of it is already in there (DynAPI 2.54).
The only thing missing is two lines in the DynLayer constructor, which as
you specified are:
In dynlayer.js, make the DynLayer function end with:
// These aren't used unless listeners.js is included
this.eventListeners = [];
this.hasEventListeners = false;
};
I have been working on some complex stuff recently, and this makes their
functionality possible.
Thanks again,

The problem is the objects share the same eventListener array [in your
example it can be verified with an alert(scrollpane1.eventListeners ===
scrollpane2.eventListeners); line].
So, how to fix it? I wasn't able to find a nice way to do it so the
following kludge will do for now...
(Because eventListeners are a rather fundamental aspect of the code it is
less of a kludge than it really is :-)
In dynlayer.js, make the DynLayer function end with:
// These aren't used unless listeners.js is included
this.eventListeners = [];
this.hasEventListeners = false;
};
and change one line in listeners.js:
DynObject.prototype.addEventListener=function(listener) {
if(!this.hasEventListeners) { this.eventListeners = []; } //
<- This changed
this.hasEventListeners = true;
for (var i=0;i<this.eventListeners.length;i++) if
(this.eventListeners[i]==listener) return;
this.eventListeners[this.eventListeners.length]=listener;
}
NB: I only made a quick-and-dirty test-case, and I got the desired results
with these changes. Please check so it doesn't break anything else!
