can't remove items from the selectMenu

[waq]

I am using selectMenu as:

<a4j:region selfRendered="true" id="text">
 <h:selectOneListbox id="symbol" value="#{user.name}">
 <f:selectItems value="#{user.temp_list}" />
 </h:selectOneListbox>
<a4j:commandButton action="#{user.getData}" reRender="symbol" value="Get"/>
</a4j:region>

temp_list has following three values when page loads:

temp_list.add(new SelectItem("Sunday"));
temp_list.add(new SelectItem("Monday"));
temp_list.add(new SelectItem("Tuesday"));

Now in user.getData i want to remove items one by one based on the selection made by the user. The code is:

temp_list.remove(0);
this.setTemp_list(temp_list);

But the problem is that if user selects Sunday for example, it remove it from the list but next time when user select Monday it removes monday but BRING BACK SUNDAY AGAIN IN THE LIST. Why is it so?

<h:selectOneListbox id="day" value="#{CreateMgtTsheet.t_date}" >
 <f:selectItems value="#{CreateMgtTsheet.date_list}"/>
</h:selectOneListbox>

<a4j:commandButton action="#{CreateMgtTsheet.createMgmt}" reRender="hours1, day"/>

public class CreateMgtTsheet {
 private List<SelectItem> date_list;
 private String t_date;

 //setters and getters

 public CreateMgtTsheet() {
 date_list = new ArrayList<SelectItem>();
 date_list.add(new SelectItem("Monday"));
 date_list.add(new SelectItem("Tuesday"));
 date_list.add(new SelectItem("Wednesday"));
 }//end constructor
 public String createMgmt() {
 //want to remove items here and i tried this
 temp_list.remove(0);
 this.setTemp_list(temp_list);
 //but its not working
 }
}

No temp_list, createMgmt doesn't return anything, etc.
I've posted an example for you in the second topic. Please take a look.
