Does redirect.captureCurrentRequest() capture request parameters which are part
of the URL as well?

I am lost Gavin. Are you suggesting that I used a page parameter for every page
in my web application?
It would be nice to have the following in components.xml:
| component name=themeSelector
| property name=availableThemes
| valueoriginal/value
|
Gavin,
Could you please be more specific? Does that mean I'll have to add
@RequestParameter to the getTheme method of the current ThemeSelector in Seam
1.1 and recompile it?
What I am trying to do is to list the themes in one single line as links
instead of having them in a drop down menu with
You might need to get jems-installer-1.2.0.BETA3.jar since JBoss-4.0.5-GA does

Where can I specify that the value of themeSelector.theme be set to thm.value?
How would using h:commandLink be different from s:link and h:outputLink?
Here is what I have currently:
| c:forEach items=#{themeSelector.themes} var=thm
| h:commandLink action=#{themeSelector.select}

Okay, but where should I report this issue? Do they have a forum, JIRA or
something similar. Please don't tell me that the only thing they have is the
mailing lists.

Try not to use the Servlet API unless you have. Try something similar to this:
| @In
| private FacesContext facesContext;
| private HttpServletRequest request;
|
| public void initComponent(){
| request =
(HttpServletRequest)facesContext.getExternalContext().getRequest();

I would appreciate a comment on this guys. It is kinda embarrassing to wakeup
in the morning just to find an email saying that the gallery section of the
site is not working again.

Hello,
I have a ui:repeat tag in items.jsf that gets an ArrayList from a stateless
session bean after performing a search based on a pattern entered by the user.
This works just fine, however, when the conversation id goes up items.jsf shows
only one item even though the database returns more
I am trying to do something similar to the RSS sample as in fisheye of JBoss
Seam:
http://fisheye.labs.jboss.com/browse/JBoss/jboss-seam/examples/blog/view/index.rss
However, the link elements do not get rendered properly as you can see here:
| ?xml version=1.0?
| rss version=2.0

Injecting an EntityManager into a servlet is not recommended since the former
is not thread safe. Here is what I do in my current web application:
| @PersistenceUnit(name = myPU)
| private EntityManagerFactory factory;
|
| protected void doGet(HttpServletRequest request,

With EJB3 the application server makes sure that your methods are executed
within a transaction. This is not the case with Servlets so you have to start
and commit the transaction yourself. Here is the code:
| UserTransaction utx = Transactions.getUserTransaction();
| if(utx.getStatus() !=
| em.joinTransaction();
| em.createQuery(query)
| .setParameter(param1, param1)
| .getSingleResult();
| utx.commit();
|

In my case I get Exception Processing ErrorPage when I try to access a jsf
page that does not exist such as doe.jsf.
According to the following post on one of the mailing lists, having jsf/xhtml
to handle error pages is not possible.
Update: I managed to get the view id using two independent approaches:
The first approach gets the view id from the request parameter map using the
key jsf_viewid. I am not sure whether this key is standard or specific to an
implementation of JSF.

No it is not a bug, here is a quote from the docs anonymous wrote : We start
a jPDL-based pageflow by specifying the name of the process definition using a
@Begin, @BeginTask or @StartTask annotation
| @Begin(pageflow=numberguess)
| public void begin() { ... }

Let me clarify few things
First, @Local is used to mark your local interface and @Entity is used to mark
an implementation of the interface. So using them together does not make much
sense.
Second, SelectItem is a model that holds the state of a single item of a JSF
component. It is meant for
In short, how can I keep track of the GET request parameters and the URL when
users login and logout?
For instance, blogEntry.jsf depends on a request parameter called id and a page
action entryAction.setEntry. Moreover, login and logout are performed using the
two page actions
How can I have more than one page action for the same view-id? Currently only
the last action in the list is executed, in this case setPaper. If the two
actions are switched, userChallenge gets executed.
| page view-id=/paper.jsf action=#{loginAction.userChallenge}/
| page
Don't worry about the missing a in page view-id=/paper.jsf
ction=#{paperAction.setPaper}/
It is only a typo. The actual pages.xml is correct.

Hi Gavin,
Do you have an plans to add this feature in the current CVS or future releases?
Having more than one page action would simply a lot of things especially for
restful application.

How can I disable auto convertion for request parameters that are of type
Integer? I'm not sure but it looks like that Seam perform the conversion during
the render response phase. In my component I have this:
| @RequestParameter(pn)
| @Out(value=pn, required=false)
| private Integer
I have an Entity bean called PaperDetails and a page called newartwork.jsf
which can be used to create a new PaperDetails.
| @Entity(name=gs_paper_details)
| public class PaperDetails implements Serializable{
| @Id
| private int id;
|
| @NotNull
| private
What should I do to fix it? The action is stateless in nature in that the user
uploads a file with some details, in this case newPaperDetails, and store them
in the database.
The reason I used @Out and initPaperDetails is because that the newartwork.jsf
page complains about not being able to
Sorry for not being clear.
After taking a closer look at web.xml I noticed that the FacesServlet handles
all the requests to /seam/. So this applies to index.rss as well, please
correct me if I am wrong.
I got confused becuase in my current setup I have *.jsf mapped to the
FacesServlet. So I
The ui:repeat needs a list of objects to iterate over, this has nothing to do
with support. You can find an example is the dvd-store sample application
bundled with Seam.

I would love to see a chapter or even a section dedicated to design patterns in
the upcoming Seam Book. Discussing new patterns specific to Seam and why some
of the current J2EE patterns are obsolete is definitely a plus.

Try setting the variable to null:
Contexts.getSessionContext().set(user, null);
You can read more about this under section 2.1.8. Context variables in the
