[jboss-user] [JBoss Seam] - Bean: org.hibernate.collection.PersistentSet, property: 0
Hi
I have a OneToMany relationship . When i try to access a value in the
secondary table using an EL as follows
#{usersHome.instance.refUserses[0].id}
I get an error as follows
javax.el.ELException: /Users.xhtml: Bean:
org.hibernate.collection.PersistentSet, property: 0
I used seam-gen to generate the code and modified the xhtml to add the above
reference.
Can somebody point me what I am doing wrong
I am running Seam 1.1 CR2
Regards
Hari

Hi I checked the code and the properties are ArrayLists. As I said I just used seam-gen to generate the code and added an extra relationship in the table . I then changed the view to additionally display the sub table and pass the key as a request parameter Thanks Regards Hari View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3995420#3995420 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3995420 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

[jboss-user] [JBoss Seam] - Need advice on using resultList and pagination
Hi I have been working with for the last 4 weeks and I have a query on using the resultList function. I used seam-gen and have been playing around with the code. My application has one main table and a lot of child tables The default code to display the child tables was to use ,h:datatable value=ChildTableEntityHome.resultList . I changed this to h:datatable value=parentTableEntityHome.getChildren Things worked with this but the pagintion has stopped working . I dug around and found the implementation of createQuery . I am thinking of modifying the ChildTableListcode to fetch only the results (i.e.) change the getEjbql method to include the foreighref if present The question I have is this : Will this work ? Is this the best way to go about this or should I implement the equivalent of the getResultList in the parentEntityHome.getChildren method also Thanks and regards Hari The question I have is this View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4002970#4002970 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4002970 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
[jboss-user] [JBoss Seam] - Using conversations causes the pages to be cached
Hi
I have been trying to use a long running conversation and I am facing the
following problem . Once the conversation is created Any link that I click
always takes me to the first page that was displayed after the conversation was
created
This is what I did :
I have a method called searchItem which I have annotated with a @Begin
(id="myconv", join=true)
public void myMethod() {
}
I also included this method in the action parameter of the
.page.xml
I can see that the action is executed . After this visiting debug.seam shows
that a conversation named 'myconv' is created.
But after this all the links have a [EMAIL PROTECTED] as request parameter even
though they are not present in the s:link parameters. And the browser displays
the first page ( i ensured that there is no browser caching etc) .
Can u let me know how I can proceed ..
Thanks
Regards
Hari

Hi I am trying to modify the seam-gen generated code to support clicable lists .

[jboss-user] [JBoss Seam] - seam-gen , Authenticate and EntityHome
Hi
My application uses the generate-entities to reverse engineer an existing DB
schema . I am using the pages generated using seam-gen.
I am trying to plug in the authentication and I am wondering what is the
correct way to go about it .
I did the following in Authenticator.java
@Out (scope=Session)
User user;
and in the authenticate method I set the user object.
But the pages generated by seam-gen refer to the UserHome object instead of
user.
When I try to do a
@In (create=true)
@Out (Scope=Session)
UserHome userHome
OR
userHome = Component.getInstance("userHome)
things do not work . The userHome object if viewed using the debug.seam shows
illegalStateException for the Collection objects
So should I
a) rewrite the pages to refer to user instead of userHome . If that is the
case can I use the persist methods of EntityHome or should I write those
methods again
b) Any other way to solve the problem ? Is there are different approach to
authentication
Thanks in Advance
Regards
Hari

[jboss-user] [JBoss Seam] - Two war files with the same code base
Hi For the purpose of development our team uses Seam 1.2.1 . So we generally change the name of the project and thus create 2 different WAR files and then deploy them to the same jboss server . While I was trying to debug using the java remote debugger I found that I was hitting the break points of my colleague. This brings me to the question : a) Is this style of development acceptable (i.e. 2 WARs with the same class names etc ) . If not what is the preferred method of development ? b) If java does get confused with the class names as I can see the debugger hitting this problem will Seam have the same problem ? --Regards Hari View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4043648#4043648 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4043648 ___ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user

[jboss-user] [JBoss Seam] - jboss seam and saving to the database
Hi
I am using Seam 1.1.6 and I am facing the following problem
" Trying to save values to the database redirects me to the Seam debug page on
an exception . I am trying to redirect to my page but I am unable to do ".
The following is what I have done
-- I have a database table with constraints on the table ( unique )
-- Used seam-gen and generated the code for the tables
-- Wrote a new method in the entityHome to call the persist method
public String handleRegistration( ) {
try {
persist();
return "test"
} catch (Exception e) {
return null;
}
}
-- I have entries in the navigation.xml to redirect the output on
"test" to the proper page
-- I have entries in the exceptions.xml file but that does not
help . I also have the 'catch all' exception.
Problem :
On entering a non unique value I get redirected to the Seam's debug page .
My understanding was that returning a null would show the same value .
Can somebody tell me what I am doing wrong and what is the correct way of
handling this
Thanks
Regards
Hari
PS : The rest of the features of JBoss Seam really rock . I am just unable to
get this simple thing to work

[jboss-user] [JBoss Seam] - Build system
Hi I have been using Seam 1.21.GA for my project. I am looking for some advice on having a build system. Some of the common problems I am facing are a) No help on GUI for using the rich:tags etc. Solution : I am using the JSF facelet files as jspx files so that eclipse provides some sort of tag completion b) No way to check the validity of the facelets files. ( i.e. there is no way to check if there is a managed bean by this name / or a method is available . ) This is becoming a big problem for the team since it takes time to deploy / explode and then catch the error . Is there a better way to check for the presence of the beans / methods during compile team. Any suggestions ?

The validation happens but Seam proceeds to the after phase and then fails when it tries to persist the form .
