Model update error

Question

Hello
i have a list of usernames in a listbox, when i select one user and press the commandbutton i see the id of the user - so far so good.
<h:form id="myForm">
<h:selectOneListbox value="#{selectedUserBean.selectedUser}"
    converter="User">
  <f:selectitems value="#{userListBean.userList}"/>
</h:selectOneListbox>
<h:commandButton action="submit" value="submit"/>
<hr/>
User id:
  <h:outputText id="edit_id" value="#{selectedUserBean.selectedUser.id}"/>
</h:form>selectedUserBean: SessionBean
userListBean: RequestBean
public class User {
private String name;
private String id;
getters/setters...
}But now i want to change the user id. so i replace the outputText by
<h:inputText value="#{selectedUserBean.selectedUser.id}"/>if i now select an user and press the button i always get the error "converter error duringModel update for component with id: edit_id". And the inputText filed shows no value.
can someone help me?

Yes indeed! It helps! I though the conversion was implicitly made by JSF...
The problem was that I got a selectOneChoice that look like this:
<af:selectOneChoice id="client" styleClass="longCombo"
label="#{messages.cashTrade_client}" simple="true"
value="#{cashEntryController.formBean.client}"
valueChangeListener=
"#{cashEntryController.synchToClient}"
binding="#{cashEntryController.client}"
autoSubmit="true">
<f:selectItems
value="#{cashEntryController.clientList}"/>     </af:selectOneChoice>
The values that are put in the SelectItems are converted automatically, let's say from String to Integer. But the value bound in the "value" attribute needs to have the same type as SelectItem.getValue().
Since I'm using the same method to populate all my selectOneChoice in my page and they either have String or Integer as value bound to the "value" attibute, I got this message all the time. So, Instead of using one or the other, I have put Object and now, it works fine.
