Have a look at
https://github.com/qooxdoo/qooxdoo/blob/21dfbf80636feb4caa95f9579c18ced3286d1843/framework/source/class/qx/ui/mobile/list/provider/Provider.js
Copy this class inside your project and extend it.
Line 100
Remove the clone part, and make a new item renderer every time with "new"
keyword.
Then it should work for your purpose...
But be aware to find a way to remove (dispose) all those items again on
re-rendering. Overwise you will get memory leaks if you render again and again.
Additionally... this way might cause memory leaks if you put a lot of items
inside. Maybe an amount about 200 items may be critical.
If you found a way, it would be great, if you would post your solution again.

Betreff: Re: [qooxdoo-devel] Listener problem on listitems in another list
Thanks for the reply.
So there is no way of working around this? I can select the items individually
( at least the color is changed when i click on it ) and i can make them react
to the "tap" event.. Any idea how to find out which item i selected using the
tap event ?

<christopher.zuend...@1und1.de<mailto:christopher.zuend...@1und1.de>>:
The qx.Mobile List is not intended to contain interactive ui element itself. It
should just display informations, and make it possible to select one specific
items. Each list item is clone of the original renderer, and that is why you
are not able to click one of the child items inside a list item.
This is because of performance issues. As a list can contain a huge amount of
items, creating child widgets needs additional listeners etc. which may lead to
memory leaks.
I would listen to changeSelection event on a the list, open another page with
the child list, and then select another item out of this list.
This is also the typical mobile app navigation flow you may know from iOS.
We had a meeting 2 weeks ago about enhancing the list to be interactive, and
contain UI elements. Maybe we will enhance the list, till next release.
