Hmm... I have the following code in my mind:
...
| @DataModel
| private List<WhatEver> whatEverList;
|
| @PersistenceContext
| private EntityManager em;
| ...
|
| @factory("whatEverList")
| public void populateList() {
| whatEverList = em.createQuery("from WhatEver").getResultList();
| }
| ...
So how to come from that java.util.List to a ListDataModel?
Doc:
I agree with you. A growing FAQ list with the possibility of user contribution
would be great. Searching the forum often is a mess since the important
information is hidden between tons of posts or in threads with misleading
titles. In addition to that the search function often delivers you threads that
don't contain any helpful information.
Furthermore I suggest a list of "common mistakes". I mean, you often get
exceptions and don't know where they come from. Or something just doesn't work
the way you want to. And if you find a solution after some cups of coffee why
not to record it somewhere? Another one will be grateful not to run that
gauntlet again. Your entity in an editor page is null and you get a model
update failure? No worries, mate, just add the forgotten @Name annotation to
your entity bean and it will work (that's what I ran into today *g*).
Moreover, what about a repository of useful code pieces, templates and patterns
contributed by Seam users? Never reinvent the wheel ;). Be it CRUDs or template
method patterns for not repeating yourself over and over (like posted
yesterday), all this can speed up your development. You're already at home with
your loved ones while the Spring coders still sit in the office ;).
I don't demand perfect software for this. The Seam team has enough more
important things to do. Little hacks, maybe a speziell moderated subforum,
could be sufficient and very very helpful.
