I have an administration bean that contains a list of users and then a
dataTable that the user can select a user to edit or delete (or click an add
button on the page to create a new user).
I wanted to start the conversation on add/edit. The problem I am having is that
my methods are never called when the bean is in the conversation state.
Bean:
@Stateful
| @Name("userAdmin")
| @Interceptors(SeamInterceptor.class)
| @Scope(ScopeType.CONVERSATION)
| @TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
| @RolesAllowed(Roles.USER_ADMIN)
| public class UserAdminAction
| extends FacesBean
| implements UserAdmin
| {
| @In(create=true)
| private EntityManager entityManager;
| private List<User> users;
|
| @Out(required=false) @Valid
| private User editingUser;
|
| /**
| * @return Returns the editingUser.
| */
| public User getEditingUser()
| {
| return this.editingUser;
| }
|
| /**
| * @see
org.bethanyefree.beans.admin.UserAdmin#setEditingUser(org.bethanyefree.data.User)
| */
| public void setEditingUser(User editingUser)
| {
| this.editingUser = editingUser;
| }
|
| @Begin(join=true, ifOutcome="edit.user")
| public String editUser()
| {
| if (editingUser == null)
| return null;
|
| userPwordChanged = false;
| initUserData();
| return "edit.user";
| }
|
| @Begin(join=true)
| @TransactionAttribute(TransactionAttributeType.REQUIRED)
| public String onLoad()
| {
| if (load())
| return null;
| return "failed";
| }
| ...
|
Pages.xhtml:
| <pages>
| <page view-id="/administration/users/index.xhtml"
action="#{userAdmin.onLoad}" />
| <page view-id="/administration/users/details.xhtml"
action="#{userAdmin.checkEditing}" />
| </pages>
index.xhtml:
<t:dataTable value="#{userAdmin.users}"
| var="_user">
| ...
| <t:column>
| <t:commandLink
| action="#{userAdmin.editUser}"
| styleClass="imageButton"
| rendered="#{!_user.system}">
| <b:imageButton url="edit" />
| <seam:conversationPropagation type="join"/>
| <t:updateActionListener property="#{userAdmin.editingUser}"
| value="#{_user}"/>
| </t:commandLink>
| </t:column>
| ...
|
When I click the edit button nothing happens (setEditingUser and editUser
methods are not called). If I change the bean's scope from CONVERSATION to
SESSION everything works fine. I've tried just about everything I can think of:
* @Begin on the onLoad, begin not on the onload
* seam:link instead of commandLink
* seam:link instead of commandLink with propagate = begin and @DataModel on the
users and @DataModelSelection on the editingUser
* Begin on the setEditingUser
And a bunch of other permutations involving the propagateConversation settings
in both the seam link and a param to command link, using or not using begin,
using updateActionListener vs. data model and data model selection, using the
data model's name vs. bean.users method of referencing.
I have had no luck with any of these permutations. The only way I got it to
work is using a SESSION bean (which is not what I am after).
I am obviously missing something, any ideas on what?
Thanks,
Andrew
