[jboss-user] [JBoss Seam] - Re: How can I pass parameters to action methods
FWIW, I should have mentioned that passEdit.selectPass(pass) was getting called but that the pass parameter was null. In any event, I switched over to using a page parameter for the pass id. It seems like this is probably better anyway (bookmarkable).

[EMAIL PROTECTED] wrote : So you need to find another way to pass an object
from request to request. One way is to pass its identifier and to load it from
the database in the second request. Another is to stick it into the session an
retrieve it from there by identifier.
But the booking app does pass the object as a parameter [from main.xhtml]:
h:dataTable id=hotels value=#{hotels} var=hot
rendered=#{hotels.rowCount0}
| ...
| s:link id=viewHotel value=View Hotel
action=#{hotelBooking.selectHotel(hot)}/
The only reason I can guess why this works is that the hotels DataModel
property is outjected from a session-scoped SFSB. However, I read in one of
Dan Allen's articles on IBM that anonymous wrote : Outjected variables are
placed directly into the variable context, independent of their backing bean.
So this suggests that it shouldn't matter.
Continuing...

Doesn't it depend on what the bounds of the conversation are? According to the
Yuan/Heute book, anonymous wrote : The default conversation scope spans only
two pages
However, I find this statement a bit misleading. If you read further, it
suggests that is really a single request/response cycle. And wouldn't this
then explain why trying to pass the object using default conversation scope
doesn't work? But then how does it work in the booking app, unless the scope
of the component outjecting the property has some influence on the lifecycle of
the outjected property.
Clearly I'm missing something I need to know about how all this works. Please
someone explain.

Apologies to Yuan/Heute, there's really nothing misleading about their statement. They spelled it out pretty clearly when I reread section 7.1.

[jboss-user] [JBoss Seam] - Re: How can I pass parameters to action methods
Ok, so I'm not insane (at least not due to this ;-) )
But I'm doing it just like it's done (famous last words) in the booking demo.
That is:
| @Stateful
| @Name(passSearch)
| public class PassSearchAction implements PassSearchFacade {
|...
| @DataModel
| private ListPass passList;
|
|
|
| rich:dataTable id=passList
| var=pass
| value=#{passList}
|rendered=#{not empty(passList)}
| ...
| h:column
| f:facet name=headerAction/f:facet
| s:link view=/passEdit.xhtml
|value=Select
| id=pass
| action=#{passEdit.selectPass(pass)}
| /s:link
| /h:column
| /rich:dataTable
And the magic ain't happening. Maybe this is no longer a recommended way to do
it, but I'd like to know why it's not working for me.

Can you define variable argument EL functions in tld files, as in:
| function-signature
| java.lang.String concat(java.lang.String...)
| /function-signature
public static String concat(String... strings) {
| StringBuilder sb = new StringBuilder();
| for (int j = 0; j strings.length; j++)
| sb.append(strings[j]);
| return sb.toString();
| }

No, its not supported by EL.

[jboss-user] [JBoss Seam] - Re: How can I pass parameters to action methods
You need to understand the JSF request lifecycle. In the request in which your page is rendered, page.globalListingsId can be successfully resolved in some context. Apparently it can't be resolved in any context (session, conversation, event, etc.) when you do the next request and execute the action. The callThisAction(parameter) syntax in the EL is really just a shortcut for a lookup/injection of that parameter contextual variable that happens when the action is executed.

[jboss-user] [JBoss Seam] - Re: How can I pass parameters to action methods
My requirement is to get an identifier in which link I have clicked in the
backing bean. I am able to find a solution for this.
In XHTML File
-
c:forEach items=#{listingSearch.pagesLinks} var=page
s:link action=#{listingSearch.next()}
value=#{page.globalListingId}
f:param name=linkId value=#{page.globalListingId} /
/s:link
/c:forEach
In Backing bean
---
@RequestParameter
private String linkId;
public void next() {
System.out.println(You Clicked on link Id : + this.linkId);
return;
}
or
FacesContext facesContext = FacesContext.getCurrentInstance();
HttpServletRequest request = (HttpServletRequest)
facesContext.getExternalContext().getRequest();
String linkIdFromCtx = ((String[])request.getParameterMap()
.get(linkId))[0];
System.out.println(Ctx: You Clicked on link Id : + linkIdFromCtx);

You need to look at the Seam example applications, or really, any JSF example application. I often had the same reflex when I started learning JSF and tried the same approach as you. You can not pass objects between requests by putting them into a link. Check the booking demo app and how it uses @DataModel and @DataModelSelection, this is what you probably want.

I can't use DataModel and DataModelSelection because I can't use DataTable. I need to render the links horizontally. Is there anyway I can render DataTable horizontally?

Btw, don't use JSTL with JSF, it's a bad combination. You are already using Facelets, so add xmlns:ui=http://java.sun.com/jsf/facelets; and work with ui:repeat instead.

Sorry to jump in here but I actually had the same problem! [EMAIL PROTECTED] wrote : ...And the last and best way is to put it into the conversation context in the first request, name the context variable in the action method as a parameter, and let Seam look it up from the conversation context in the second request. This is really what Seam is about. As far as I understood it he has a list as a context variable and wants to pass the id of an object contained in the list as action method parameter. So the list is within conversation context but JSF doesn't resolve the id to some string that is therefore null but it would work if he would write listingSearch.next(3) - in case page.globalListingId would be 3. So is there any way to force JSF to resolve page.globalListingId to a string (assuming it is an Integer, String, ... - anything that can be cast to string without problems)? I would greatly appreciate any hints / 2 line examples because this has been some pain for me too. Thanks a lot in advance!

No, JSF is dumb. You could create a Facelets function and call it like this:
#{myFunctions:myToString(o)}
