i found a *terrible* way to work around this issue, but it works. i moved the
field.setSelection call to a delegate, which allows it to work:
===
var del = new lz.Delegate(this, "selectEnd");
lz.Timer.addTimer(del, 1);
</method>
<method name="selectEnd" args="ignore">
this.field.setSelection(this.value.length);
</method>
===
this should help narrow down what the problem is with the TLF framework.
