I developed a JSF1.2 Application and my form looks like contains a Country SelectOneMenu and MobileField as below


<h:form>
<h:selectOneMenu value="#{mybean.selectedCountry}" required="true" >

<f:selectItem itemName="selectOne" itemValue=""/>
<f:selectItems value="#{mybean.countriesMap}"/>

</h:selectOneMenu>

<h:inputText binding="#{mybean.mobileNo}"></h:inputText>

<h:commandButton id="next" value="NEXT" action="#{regform.next}" />
</h:form>

And My Bean Scope is Session and this is mandatory for my Requirement.


My Actions:

1) Select a Country value like USA of CountrySelectOneMenu and Click Submit Button

2) Now again Select the 'selectOne' of CountrySelectOneMenu and Click Submit Then the
Previous Submitted Value "USA" is displayed as selected and a error message is Showing
'Country is Required' as this field property is reqired="true" .


So Previous Selected value is getting displayed even i select default option 'selectOne' and
displaying error Message.

I must get the default 'selectOne' Option with an error message but not the previous submitted value
to be set for SelectoneMenu .


Can you suggest a Solution for my Problem?


Thanks & Regards

Hi brajen,

The Value for SelectOnemenu default option '--SelectOne--' is ""(empty String Only) and my code looks Like:

<h:selectOneMenu class="select_field" id="country" label="#{labels.countryCode}"
value="#{countryCountroller.selectedCountry}" required="true" >
<f:selectItem itemLabel="--SelectOne--" itemvalue="" />
<f:selectItems value="#{countryCountroller.countryItems}"/>
</h:selectOneMenu>

hi

since your managed bean is in session whenever you select a value and submit that value remains in session hence selected

when you reselect the select country option with empty value since the value is emtpy error message is displayed but as the value=#{attribute} is already selected in previous submit and is in session , you got that value selected when the page is rendered


to avoid this you can clear the value value=#{attriubute} in managed bean action methos as this:

public String test(){

...............................

some process
.................................
selectedCountry = "";
return "pageNav";
}
 
It is sorta covered in the JavaRanch Style Guide.
