I'm using a session-scope stateful session bean to hold search results in a

Hi.

hello,
I'm using datamodel and dataModelSelection. I always have the first row
selected!
this is my code :
bean.java:

| private List listeChargesRegies;

| @DataModelSelection(value = "listeChargesRegies")
| @Out(required = fals
This isn't the behavior I would have expected. (I'm using 2.0 CR2.)
Is there a document that describes the order in which annotations are
"executed". Both during environment initialization and during request
processing. Anyone else think this would be a useful document to have?

up with a solid answer, so I thought I'd post this in hopes someone will find
it useful.
I have a simple data table set up such as in the Message List example, with a
clickable link in each row (to edit that object).
Are there any examples or explanations for the @DataBinderClass and
@DataSelectorClass annotations? I'm curious whether they could be used to
insert a different DataModel implementation class (for example, a data model
with extra functionality for sorting and paging).
