[jboss-user] [JBoss Seam] - Questions about injection and outjection
1)When a method in a session bean is invoked, will Seam inject all the variables annotated by @IN or just inject the variables used by the being invoked method? 2)When a Session Bean is injected as a facade, is it possible for the mthod in the session facade bean inject or outject varibales? 3)Could an injected variable such as EntitManager em be passed to a POJO method as a parameter?

[jboss-user] [JBoss Seam] - Re: Questions about injection and outjection
1) If the answer to question one is Yes, does it mean that it will inject
non-relevant variables as well? Does it affect performance ?
2) For question 2, If I have two session beans A and B. B is used as a session
facade.
| @Stateless
| @Name(a)
| public Class A ...{
|@In B b;
|public String test1()
| {
|return b.test2();
| }
| }
|
| @Stateless
| @Name(b)
| public Class B ...{
| @In String s1;
| @Out String s2;
| public String test2(String s)
| {
| s2=s+;
| return s+s1;
| }
|}
is the above codes legal ? Could I get the variable named s2 outjected?
3) For question 3, Could you give a simple example to demo that?
For example
|@Stateless
|@Name(actionA)
|public class ActionA implents ActionAInf {
| @PersistenceContext
| private EntityManager em;
|
| public String methodA()
| {
|new Bean(em);
| }
| }
How do I use the EL binding in this case?

[jboss-user] [JBoss Seam] - Generate 1000 number using facelet
Hi!, I tried to display 1000 numbers in a page under some condition. It seemed c:if and c:forEach did not work well with my condition, so I tried ui:repeat. The problem is I have to hold the 1000 numbers in a arraylist. Anybody knows better solutions that uses less memory?

[jboss-user] [JBoss Seam] - Ajax and concurrency
Hi!
I have a SFSB with like following:
|
| ..
| Doc doc;
|
| @Begin
| public void getDoc()
| {
| doc=.
| }
|
| public void preView()
| {
|
|
|
| }
|
| @End
| public String save()
| {
| if (doc!=null)
| update();
| else
|new();
|
| }
|
|
In my page there are a Preview Button and a Save button,
Sometimes after clicking the Preview button, if I click the save button too
quick. I'll get the message: Conversation is end or is busy. This is
not a problem, the real problem is I got a new duplicated reocord of doc in the
DB when I tried to edit the doc.

[jboss-user] [JBoss Seam] - Two bytes char again
Hi! In my textarea I inputed a char \\#\x\2\5\B\3;(?) and saved it to the DB. When it is retrieved for DB to the textarea, it becomes ?. This behavior is not what we want. Since we need the process string \\#\x\2\5\B\3; instead of char ?. Another problem is when we processing pages containing east asian characters, we input ?(big) as page parameter and it becomes 大 when it gets redisplayed. Thanks for any suggestions.

Hi!
I'd like to know if the links generated by s:link s:button are secure.
for example
| s:link action=#{AA.method} value=XXX
| f:param name=id value=#{object.id} /
| /s:link

is it possible for somebody to copy this link to the browser and modify the
object id in the current session so that he could see the content of other
objects?

Those *Home.java, *List.java *.page.xml , etc. were generated under seam 1.1.7 and are running under 1.2.0. I did not re-run seam to generate the projects, since I did a lot of modifications to the genrated pages. It is obvious that the code generated using 1.2 seam-gen are different from that using 1.1.7. I'd like to know what could cause this exception and any simple solutions to fix that. thanks.

[jboss-user] [JBoss Seam] - pass parameters from page to page
Hi!
Anybody knows how to pass parameters from one page to another page?
for example in pageA.xhtml I have
| s:link value= view=/pageB.xhtml
| f:param name=para1 value=para1/
| /s:link
|
in pageB.xhtml I'd like to do the following:
| s:link value= view=/pageC.xhtml
| f:param name=para1 value=#{para1}/
| /s:link
|
is that possible without any extra configuration?
Since I am trying to use EntityHome and don't wan't to add a lot of codes to
the extended EntityHome.
I did some testing and found the EL #{para1} is always null.
Thanks a lot!

[jboss-user] [JBoss Seam] - Re: EntityManager: For newbies or to close gaps in your know
Hi! bfo81,
great!
I have one question as following:
Suppose I have two tables
| user(id, name)
| userlog(id,userid,content)
|
I'd like to create a new user and write the log at the same time.
Suppose I use extended persistent manager.
I have the following code:
| @In @Out user;
|
| @PersistenceContext(type=EXTENDED)
| private EntityManager em;
|
| public void new_user()
| {
|
| user.setName(user);
| Userlog userlog=new Userlog();
| userlog.setContent(register);
| userlog.setUser(user);
|
| -
|
| }
|
the question is:
1)Do I need to em.persist to save user and userlog?
2)If it is needed. Which one is first? user or userlog
thanks in advance
