Hi John,
first of all thanks for the reply.
I know that my 'converters' do not work the way they should. They were just
desperate things that I've tried. I should have left them out of the
playground example, sorry!
A parser/formatter that transforms "5 minutes" into 300 (or back) is
available, but:
How to *select* the right ListItem by its 'model' value?
In previous qooxdoo versions (0.7.x) a ListItem of a ComboBox could be
selected by something like this:
<code>
// 'cb' is a ComboBox instance
var model = ""+300; // ...had to be string back then
cb.setSelected( cb.getList().findValue(model) );
</code>
But this 'concept' has not survived all the upgrades 'till now :/
Nevertheless I think that I might have to think completely different here.
Thanks so far and nice weekend,
Peter
