Now I think it's impossible to insert rows in a list created with
ListView via AJAX because children items id's are just their index in
the list. So when I insert something in the list, I have to change id's
of all lower items and do the same thing with scripts on the client
side. It's getting too complex and slow.
So I'm trying to create CustomListView by copying it from ListView and
extracting children item id generation strategy. But I have a problem -
when I create new list item during ajax request, add it to a
CustomListView instance and append to AjaxRequestTarget, I get the
following error:
ERROR - RequestCycle - Unable to find the markup for the
component. That may be due to transparent containers or components
implementing IComponentResolver: [MarkupContainer [Component id = ad4,
page = listview.ListViewPage, path =

I looked through AbstractTree.updateTree code, but didn't find any
special magic to insert new rows.. Please help!
