Struts bean

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:

 

For a plugin, I'm writing an Action class, with my methods and variables. On my Action, I have three simple pojo objects, with the getters/setters:

 

private Bean bean;

private Bean2 bean2;

private Bean3 bean3;


public Bean getBean(){

     return bean;

}


public void setBean(Bean bean){

this.bean = bean;

}

...

 

All these objects have a title and description as variables, so on my ftl, I have these inputs:

<input name="bean.title" />

<input name="bean.description" />

...

 

When I first print the page (input method of my action), my input are well filled with the value I put on the action. But when I submit the page, all my beans stay at null! And I don't know why

 

Could someone please tell me if I am missing something? I thought that with struts2, you just have to put you're objects (String, Integer, Self made objects, etc.) on the Action with the good getters/setters and Struts take care of this automatically.

 

Thanks!

    Could you post the full Java / FTL code here?

      Hi Aaron, I don't think I can post all the code because it's a private project (Actually, I'm modifying one of your commercial plugin) but here is the partial code:

       

      ftl:

      <@s.textfield name="bean.title" />  

       

      Java action:

      public class testAction{


          protected Bean bean;


          public Bean getBean() {
              return bean;
          }


          public void setBean(Bean bean) {
              this.bean = bean;
          }


      ...

      }

       

      Java pojo:

      public class Bean{


           private String title;

           private String description;


           public String getDescription() {
              return description;
          }


          public void setDescription(String description) {
              this.description = description;
          }


          public String getTitle() {
              return title;
          }


          public void setTitle(String title) {
              this.title = title;
          }


          public Bean() {
          }


      }

       

      Thanks

    Found my problem, for those who got the same, you have to override the acceptableParameterName method from JiveActionSupport.
