Hello, i use Jdev 10g

values for f:selectItems in bean i'm get from DB and set to list

             list = new ArrayList<SelectItem>();
      
                ViewObject vo = am.findViewObject("CountryView");
                while (vo.hasNext()) {
                    CountryViewRowImpl row = (CountryViewRowImpl)vo.next();
                    SelectItem item = new SelectItem();
                    item.setValue(row.getCountryCode().stringValue());
                    item.setLabel(row.getCountryName());
                    list.add(item);
                }

<af:iterator value="#{informClient_bean.fields}" var="row"
                               rows="40">
                    <af:switcher id="sw1" facetName="#{row.type}"
                                 defaultFacet="Text">
                    
                      <f:facet name="9">
                        <af:selectOneChoice value="#{row.value}"
                                            requiredMessageDetail="обязательное поле не заполнено"
                                            autoSubmit="#{row.autoSubmit}"
                                            immediate="#{row.immediate}"
                                            label="#{row.label}"
                                             required="#{row.requared}"
                                            readOnly="#{row.readOnly}"
                                            onmouseup="validMask();"
                                            shortDesc="#{row.shortDesc}">
                                            
                          <f:selectItems value="#{row.list}"/>
                        </af:selectOneChoice>
                      </f:facet>
                  </af:switcher>
                  </af:iterator>

when working with a form, select a value from the code we get the selected value .... but sometimes (for example, if the field is read-only true) then the selected value is not the same.

value label
1 a
4 b
5 c

If I choose "b" when working on the shape of the code will be 4
if I open the form and read only true in the bean I get a code 1 and the value of "a"
