Dear Sir / Madam ,

Good Afternoon ,

I have problem with following codes ,

JSF :-
------

<rich:comboBox id="RelationShip" valueChangeListener="#{memberBean.relationshipChanged}"
    rendered="#{sourceBean.profile.familyInformationEnabled}"
    suggestionValues="#{memberBean.relationships}"
    value="#{memberBean.relationship}"
    enableManualInput="true" directInputSuggestions="true"
    defaultLabel="NA"
    onselect="validateRelationshipGender();">
     <a4j:support event="onselect" ajaxSingle="true" reRender="ContactPersonGender" />
</rich:comboBox>

<rich:comboBox id="ContactPersonGender"
                                        rendered="#{societyProfileBean.currentSociety.profile.familyInformationEnabled}"
                                        suggestionValues="#{member.genders}"
                                        value="#{member.gender}"
                                        enableManualInput="false" directInputSuggestions="true"
                                        defaultLabel="NA">
                                    </rich:comboBox>

JS Code for Validation :--

function validateRelationshipGender() {

        var gender, genderForm;
        gender = document.getElementById("NewUser:ContactPersonGender").value;
        genderForm = document.getElementById("NewUser:ContactPersonGender").disabled = true;
        if (gender == "Male" || gender == "Female") {

            genderForm = document.getElementById("NewUser:ContactPersonGender").disabled = false;

        }

    }

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

Validation is not working for me , gender values comes form table , and relationships from bean.

What i need means once i select relationships it take some time to come value from bean,in that processing time i want disable and enable that gender drop-down box

My problem is while i give JS validation its not working , once i removed validation code its working fine ,





Give some guidance to proceed further ,

Thanks in advance ,
