[jboss-user] [JBoss Seam] - Re: EL enhancements in Seam 1.2.1
This is not how doStuff(argument) works. What you are trying to do is a common
error.
Think about when #{projectPlanHome.edit(pp.id)} will be evaluated: During
rendering of the page. However, if you check the source of the rendered HTML,
you will see that pp.id has not been replaced with a value, it is still pp.id.
So when you click the link, Seam will on the server call your
projectPlanHome.edit() method and it will resolve pp.id as an argument to
that method. At that time, pp is long gone.
What you want is @DataModelSelection, see the Seam documentation and examples.

[jboss-user] [JBoss Seam] - Re: EL enhancements in Seam 1.2.1
In other words, and as the documentation says, what you just wrote is
equivalent to this:
|
| @In(#{pp.di})
| Long projectPlanId;
|
| public String edit() {
| ...
| }
|
That also doesn't work because at call time of edit(), no #{pp.id} can be
resolved - pp is just the loop variable that is used during rendering of the
previous page.

[jboss-user] [JBoss Seam] - Re: EL enhancements in Seam 1.2.1
Thanks! Let me ask you another question related to the last one:
What about if I don't have a dataTable? In other pages I have links like this
one:
| s:link id=ppPhase value=#{projectPlan.phases['i'].name}
view=/phase.xhtml propagation=nest
| f:param name=phaseId
value=#{projectPlan.phases['i'].id}/
| /s:link
|
|
which is trying to access other page with the information of an existing
entityBean.
I achieved this using seam-gen new-entity and all my pages are RESTful, but
I'd like them to beheave with an action behaviour (or push-style). How can I
do that? Can I keep the EntityHomes and tranform them to be push-style?
Thanks for your time.

I've already tried what i was planning to do, and yeah, it works! Now, I understand the previous posts. It's needed an object in the scope of the conversation in order to evaluate the argument of the expression. Thanks! All of you, the staff of JBoss are very helpful.

I am having similar problem. I am using facelets source tag:
taglib.xml

| tag
| tag-nametest/tag-name
| sourceTest.xhtml/source
| /tag
| /facelet-taglib

| testWithParam
| /h:commandLink
| h:commandLink action=#{backingBean.testNoParam}
| testNoParam
| /h:commandLink
| /ui:composition
|
some xhtml file using test tag
| ui:composition xmlns=http://www.w3.org/1999/xhtml; ...
| xmlns:t=http://Test;
|t:test backingBean=#{testBean}/
| /ui:composition
Link testNoParam is working.

[jboss-user] [JBoss Seam] - Re: EL enhancements
What is the recommended method of executing a query for each line in a DataModel or list of entities on a page upon each load? I was thinking I could pass in the loop variable to a method that would go and execute a query. Since that's not possible, what should I do - I know how to use DataModel for doing things once you've selected an entity, but not how to do something for every entity, with regards to a list. Is there a good example of this I could check in the Seam examples?

Right, but that would only be evaluated when I click the link, whereas I would like the value to be shown when the list page is shown. For example, in a list of entities I'd like to show next to it the result of a query (i.e. that value isn't stored as a property of the entity, but is evaluated as a result of a query). I can't see how to get them all to display on the list page.

You would have to preprocess the list in your factory method. Normally you can avoid doing this by getting the datamodel right.

Here's the type of thing I'm trying to do. The point is that there are a list
of favorites, and within that list I want to specially mark those favorites
of the logged in user.
But of course, the enhanced EL expression I have in the view doesn't work. It
seems like the most intuitive way to do it, but I guess I have to look for
another option.
Hopefully you can advise as to what I can do here. Thanks.

| @Factory
| public void getFavorites() {
| favorites = entityManager.createQuery(...).getResultList();
| }
|
| public String getStatus(int id) {
| for (Favorite f : member.getFavorites()) {
| if (member.getFavorite().getId() == id) return Your Favorite;
| }
| return Not Your Favorite;
| }
