Beans stay null
Hi all!
Coming from the Struts1 world, I find Struts2 really convenient!
But I have a simple problem, maybe I miss something. I've read some
tutorials about Struts2 but didn't find something... Here it is:
I'm modifying an actual project based on struts2, spring and freemarker. I
have to add some functionnalities to a page, so I have to modify an Action,
by adding three simple pojo objects, with the getters/setters (these
class/variables names are fictional):
*
public class MyAction extends ActionSupport{
private Bean bean;
private Bean2 bean2;
private Bean3 bean3;
public Bean getBean(){
return bean;
}
public void setBean(Bean bean){
this.bean = bean;
}
...
}
public class Bean{
private String title;
private String description;
public String getTitle(){
return title;
}
public void setTitle(String title){
this.title = title;
}
public String getDescription(){
return description;
}
public void setDescription(String description){
this.description = description;
}
}*
*...*
All these objects have a title and description as variables, so on my page,
I have these inputs:
*
<@s.textfield name="bean.title" />
<**@s.textfield** name="bean.description" />
...*
When I first print the page (input method of my action), my beans are well
filled with the values I put on the action. But when I submit the page, all
my beans stay at null (debugger on the action class)! And I don't know why
It's been one day and an half that I'm trying to get this working, but I
don't why my objects stay at null after the submit of my page (I've already
checked the name of my variables, trying to rename my beans, etc.)
Could someone please tell me if I am missing something? I thought that with
struts2, you just have to declare you're objects (String, Integer, Self made
beans, etc.) on the Action with the good getters/setters and Struts take
care of this automatically (not like Struts1 where you have to declare your
beanform on the struts.xml).
Thanks!

Thanks for your help maurizio, I found something about my problem: I'm
developping a plugin on the Jive SBS Software. To do this, all the action
class must extend a JiveActionSupport class. I changed by ActionSupport
directly, and my beans are not null anymore. But I can't do this way because
the plugins on Jive must extend JiveActionSupport. I'm gonna send a mail to
their support.
Thanks

It's very strange odd. Could you attach at least your action java file,
struts.xml and freemarker template?

It's before the redirection.
I come to my page: Ok, my variables are all here
I submit my page: when It comes to my Action class (method execute) to save
the information submited, my bean objects are all null on the class, but
they are present on my request object. The only variables not null are the
simple Objects on my class (String, Integer, etc.). It's like it doesn't
want to deal with my pojo objects...

As I guess, when struts do a redirect lost your bean parameters.
Try to remove and see what happens
