Problem with SelectOneMenu

[hager]

Hello,
I'm using h:selectOneMenu and I have a problem :
I fill my selectOneMenu with a List, when i submit my form, I remove the selected Item in the selectOneMenu.
In my java code, when i debug, the selectedValue is deleted from the List, BUT when the page is submitted, the element still here.
What's the problem, please help me. thanks

mypage.xhtml

<h:selectOneMenu id="selectOneAssignable" value="#{activitesByCollaborateurCrossData.assignable}">
<s:selectItems
value="#{activitesByCollaborateurCrossData.availableLines}"
var="assign" label="#{assign.designation}"
id="selectAssignable" />
<s:convertEntity />
</h:selectOneMenu>
<h:commandLink action="#{activitesByCollaborateurCrossData.updateAssignable}">
<h:graphicImage value="img/add.png" />
</h:commandLink>

in mybean.java

public void addAssignable() {
 if(this.assignable != null){
 System.out.println("removed = "+this.availableLines.remove(this.assignable));
 this.lignes.add(assignable);
 listeAssignables.put(assignable.getDesignation(), assignable);
 Totaux.put(assignable.getDesignation(), new Float(0));
 this.updateTable();
 }
 }

[hager]

public void updateAssignable()
 {
 System.out.println("updateAssignable ");
 this.addAssignable();
 }

I don't really understand.

[hager]

hi,
I have a selectOneMenu and a commandLink.
when I click on this commandLink, I call a method which remove the selectItem on the selectOneMenu. After executing this method, in my List (java code), the element is deleted.So, the page is submitted, BUT, in my view, the element still here.
thanks.

[pmuir]

Are you updating the list outjected to the view. Show the code.

[hager]

yes, exactly

this is my code :

@Out(scope = ScopeType.CONVERSATION)
 private List<Assignable> availableLines;

 public void addAssignable() {
 if(this.assignable != null){
 System.out.println("removed = "+this.availableLines.remove(this.assignable));
 for(Assignable it : this.availableLines)
 {
 System.out.println("Lignes Restantes : "+it.getDesignation());
 }
 this.lignes.add(assignable);
 listeAssignables.put(assignable.getDesignation(), assignable);
 Totaux.put(assignable.getDesignation(), new Float(0));
 this.updateTable();
 this.assignable = null;
 }
 }
