Hi there, sorry for the delay, just got a sample minimal test case, here it is:
http://bco.homelinux.org/cosas/slinkerror.zip
Complete ear + war + jar + src + build.xml ;)
I'm running it on jBoss 4.2.1 + Seam2.

This is the simplest EntityQuery ever, but for any other case, from a more
complex one, to unwrap methods or other dynamically calculated lists, not
caching the results will be a performance issue. Maybe even a concurrent
request could change some parameter that would end up giving different

Such a quick response, such a simple thing, yet such big accomplishment.
Thank you ; )
... now some other things are broken, but I can take it from here ; )

Trying to migrate from jBoss4.0.5.GA+Seam1.2.1.GA to
jBoss4.2.1.GA+Seam2.0.0.B1, after updating lots of code, app deploys properly,
but when I try to acces initial page, an EntityHome complains and sends me to
error page:
In attribute requires non-null value: complexHome.entityManager

Tried to migrate once with no success ( currently jBoss 4.0.5.GA + SEAM
1.2.1.GA) ... will try again and report status ;)

Don't sure it's the latest, or the proper document:
http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jboss/jboss-seam/seam2migration.txt?revision=1.2view=markupsortby=date
... but:

.. then why
| h:dataTable id=regions value=#{regions.resultList} var=region
| h:column rendered=#{s:hasRole('Debug')}
| f:facet name=headerid/f:facet
| #{region.id}
| /h:column
|
s:link fetchs list multiple times, here's what happens, this is .xhtml fragment:
h:dataTable id=users value=#{selectEmployee.resultList} var=employee
|h:column ... simple columns: employee.name, employee.phone, etc ...
/h:column
|h:column
|s:link propagation=none
I have a Profile entity, so I do:
employee.getProfile().getPermissions() wich are a bunch of strings, assigned to
user at loginTime (#{authenticator.authenticate}) as roles, so xhtml uses
#{s:hasRole('role')} and java uses Profile object, hope that helps.

Didn't wanted to bloat the post, but it happens with every dataTable I have,
wheter they use query objects, my own custom beans, or even bean.property of
type list, they all get queryed again for every s:link in every row (of a
h:dataTable).
Here's a quick sample, the COMPLETE page
I use
Identity identity = Identity.instance() ;
.. (no @In) and then
identity.addRole( someString ) ;
... for each role and everything works fine.
Maybe all those Identity.instance() aren't apropiate (they should be)
View the original post :
... guess what? just found out: Even an empty s:link / will make extra fetchs
:(

Hey ffischer !! I 'm also having that problem !! random
#{org.jboss.seam.security.identity} and #{org.jboss.seam.messages} erros, I do
have ajax4jsf in web.xml, I can disable it there as you say, but then I get

dtd's must be validated :S, run through the same problem, patch/fix was, for
me, to manually download (that's a horrible patch) pages-1.2.dtd and put it in
bin directory of jboss, since my server runs dnsless and cannot validate online
resources, only pages-1.2.dtd from jboss.com was needed for

What do you mean by initializing the parameter in the first place ? isn't that
what the page parameter does ?
I'm a seam newbie having a similar problem, if I select an entity from a
h:dataTable using
s:link id=editUser action=#{userSearch.editUser(user)} propagation=join
Edit/s:link
then

starting a new conversation. By the way, i had trouble using inheritance, using
declarative approach fixed some errors, I believe that's a bug.

... or you can put them in conversation scope and make things transparent ;)

I'm having the same problem, I'm starting with seam, using EntityHome, and as
far as I understand that only propagates the parameter to the page, still has
to be injected, I use
@RequestParameter Long userId ;
however my source is nearly identical to the one in the exaples of reference
Similar problem, however, I'm using portlets, running things inside the same
JVM and everything runs inside the same app, however, in some places my app uses
TransactionManager tm = (TransactionManager)new
InitialContext().lookup(java:/TransactionManager) ;
... wich runs nice and smooth, while
Hi there, there are a few ways to interact with other portlets around, however
most of them relay on session or some messaging boxes
(http://www.doc.ic.ac.uk/~mo197/portlets/portlet_messaging/), however I'm
thinking they are not multi-browser-window/multi-tabs safe.
Think of it, browser tab A
