William,
Max checked a fix in over the Thanksgiving break that will get
newcombobox compiling -- this is in the nightly build. Unfortunately,
even though it builds now it doesn't run properly. I'm going to take
a look at what might be wrong later this week.

Subject: Re: [Laszlo-user] is there any way to make this code faster?
Check out lps/components/incubator/newcombobox
This is much more efficient for the kind of situation you describe.
It's a
data-backed combobox.

In our app, we have to be able to replace the list of items in
various
comboboxes often. So we extended combobox and added a setItems()
method.
However, the part that removes the old
items is brutally slow. In fact, it seems to be faster for us to
destroy
the combobox and create a new one than it is to remove the items.
However
destroying comboboxes at runtime just feels wrong and I'm sure
will lead
to
memory leaks and other problems. Below is our code. Any thoughts
would
be
appreciated...
<class name="comboboxex" extends="combobox">
<method name="setItems" args="list">
<![CDATA[
//First, remove items...
while(this.getItemAt(0) != null) {
this.removeItemAt(0);
}
//Then, add items passed in
for (var i=0; i<list.length; i++) {
this.addItem(list[i], i);
}
]]>
</method>
</class>
