Listview / input components repaint via ajax?
Hi
I have a listview in a panel. I have a ajax link to add items to the
list. When I click the link the listview are repainted, because I have
it in the markupcontainer just as it should. In the listview there are
some textfields, these are cleared when the markupcontainer are
repainted, I dont understand why?
I have set the setReuseItems(true). And have tried to call the
removeAll() method on the listview.
What am I forgetting?
regards Nino

Jep, I sorta thought that it wouldnt make sense for it to call removeAll...

If you call removeAll, the list view will populate itself freshly
again, so your previous input won't be remembered. Either make sure
the models that back the items are updated, or follow another
strategy, such as using a refreshing view with
ReuseIfModelsEqualStrategy.

Solved by a very simple solution just added
AjaxFormComponentUpdatingBehavior, if I need to do something more
complex i'll ask:)

You can set defaultFormProcessing to false too, and post the list with an
ajaxsubmitlink.
Btw, I have written a very dynamic list that we are using for cases like
yours. It consists of nodes that are implemented as a chained list of
fragments, each equipped with previous, next and item placeholders
(markupcontainers). It's ensured by construction that there will always be a
placeholder before and after any item. You can add or insert new items,
which you provide as fragments in a way that loosely resembles populateItem,
a new node is then created for the item and linked to the list, and *only
this* node is ajax painted. Similarly, you can remove nodes that are
unlinked from the list and hidden. This way there is never a full repainting
of the list. If you think this could be useful for you, just ask me the
code.

Carlos

Hmm just added AjaxFormComponentUpdatingBehavior to my text fields, this
works nicely..
But your help pointed me the correct way.

Of course they are cleared, because data form textfield is transfered to
model only if submited with submit button. If u repaint the panel, model is
blank. Use AjaxEditableLabel instead of TextField. It will transfer dat to
model immediately after editing.
Hope it helps, i was solving this issue a week ago.

Hold for a minute, it might be something internal.
I'll get back if it turns out not to be.
