[jboss-user] [JBoss Seam] - Dynamic number of input types

[leezard]

Hi all again, 

Now I'm trying to solve another JSF/Seam related problem and hope yopu will help me to do it :)

I have an Seam component defined as:


  | 
  | @Name("account")
  | class Account {
  |    private String id;
  |    private String name;
  |    private List<Limit> limits;
  | 
  |    // getters and setters here
  | }
  | 
  | 
  | class Limit {
  |    private String type;
  |    private Long value;
  | 
  |    // getters and setters here
  | }
  | 


Now my problem begins here: each account can have different limits number. Limits are system-wide configuration (e.g. you can have 4 different limit types defined and the you get a list with 4 items in Account instance). I can easily print all limit types and their input types using facelets <ui:repeat>:


  | <ui:repeat value="#{account.limits}" var="limit">
  |    <h:outputText value="limit.type"/>
  |    <h:inputText value="limit.value"/>
  | </ui:repeat>
  | 

But I'm affraid is't a bad solution. I want to submit form data together with limits data. Now I get NullPointerException on limits field in my action Bean. How can i properly get all the data? Do I need to use Limit as seam component also? Or do I have to use long running conversation somehow?

Thanks for replies.
