Inputfield in ui:repeat

[Dominik Müller]

Hi All,

have a problem here and i am running out of ideads to fix it.

I have a fomular with a dynamic amount of fields (based on a list from the managedbean) and i whould have editing fields for all values.
In general all works: for every element in the list i get an input element in the formular. But on submit NO VALUE will be transfered to the data objects, althought the browser post-command contains all values.
I break down my project to a very little example:

Simple ManagedBean

@ManagedBean(name="rh")
@SessionScoped
public class RepeatHandler
{

  private List<String> stringList=new ArrayList<String>();
  
  @PostConstruct
  private void init()
  {
    stringList.add("String 1");
    stringList.add("String 2");
    stringList.add("String 3");
  }
  
  public void doSome()
  {
    System.out.println("Submit This");
  }
  

  public List<String> getStringList()
  {
    return stringList;
  }


  public void setStringList(List<String> stringList)
  {
    this.stringList = stringList;
  }
}

JSF

<h:body>
<h:form> 
	<ui:repeat var="element" value="#{rh.stringList}">
		<h:inputText value="#{element}" />
	</ui:repeat>
<h:commandButton value="Submit" action="#{rh.doSome}" />
</h:form>

Somebody andy idea to solve the problem?

thanks a lot
Dominik

PS: the alternative c:forEach fix the issue in that way that the changed values will be posted to the bean, but isn't an option because of the jsf behaviour of c:forEach (changing the underlying list (or add an elemend for example) will not change the amount of shown elements)

Muler,

Root casue: I think the mapping of input text fields and backing bean is not set.

input text value:
<h:inputText value="#{element}" />

#{element} means #{StringReference}... now with this how JSF can figure out which backing bean and which property it has to set.

solution: I am not into JSF but
you can try something like

Iteration i from 0 to list size
<h:inputText value =#{RepeatHandler.stringList(i)}/>
end Iteration
