[jsr-314-open-mirror] [jsr-314-open] [ADMIN] Expert Community meeting 20100714 13:00 EDT: UIData

[Martin Marinschek]

Thanks Alexander - find below a slightly extended version of your
document (sorry to put it in a mail, but I couldn´t edit the Google
Doc). I didn´t find an issue for "supporting AJAX updates of single
rows" - can you add this, so it doesn´t get lost?

best regards,

Martin

JSF 2.1 iteration components.

1. Create root class ( interface ? ) for all iteration components:
UIRepeat, UIDataTable,and, if possible, UISelectItems,  and all
similar third-party components ( lists, trees, grids, menus ) that
iterate over its children. There would be class hierarchy similar to
the ADF/trinidad:
UICollection
-- UIRepeater
     -- UIDataTable
        -- HtmlDataTable
-- UIHierarchy
   ....
(https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=322)

2. In addition to saving state of EditableValueHolder between
iterations, save similar information for components that use internal
fields during requests. That includes UIData/UIRepeat itself ( data
model instance and saved states from children ), UIForm ( 'submitted'
property ), and any other components that can require per-row states.
Possible implementations:
Lets components do it on its own by implementing IterationStateHolder
interface with two methods saveIterationState/restoreIterationState.
Using partial state to store per-row values in the same way as it is
done between requests - this should be implemented in any case,
partial state saving in a table right now does not work.(

https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=153,

3. Support AJAX updates for a single row in iteration components, and
allow AJAX requests from inside the table to find the table
(getClientId wrongly returns the id of the row inside the client-id,
see https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=865,
duplicate of https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=738)

4. Move column rendering from dataTable to column component itself, to
create custom column components that performs some logic  ( for
example, iterate over children components to create columns 'on the
fly' like t:columns component does ) or customize column look and
fell. DataTable should relay on "Column" interface instead of UIColumn
component. ( related issues :
https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=217,
https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=225,
https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=627
, https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=756)

5. Enhance data model to support Collection interface (
https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=479
, https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=713,
https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=751),
or use arbitrary key instead of simple row number, so developers would
use database Primary Key's for JPA-based models. Custom keys also
required by hierarchal components.

Additional wish for UIData (not sure we want this?):

https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=249
Facets should accept arbitrary attributes...

best regards,

Martin
