I have a visualforce page with a couple of Required Fields. The fields are made Required on the front-end by setting the Required attribute to True. There is a picklist on the top-right corner of the page that has multiple language options. Whenever I select a value from the picklist, it fires up validations on that page and doesn't update the picklist value, hence not translating the page. It is probably due to Apex:actionsupport but I'm not sure.

I've tried using immediate="True" on actionsupport, but that doesn't seem to work.

Is there another way to create this kind of functionality? Using Javascript/Jquery or even through the current method?

Apex Function:

public PageReference translate(){
        webformObject.put('Language__c', language);
        update webformObject;
        PageReference pageRef = new PageReference(urlToCurrentPage);
        return pageRef;

Picklist Markup:

<apex:selectList id="langList" value="{!language}" size="1">
        <apex:selectoptions value="{!AvailableLanguages}"/>
        <apex:actionsupport action="{!translate}" event="onchange"/>

    Can you post all the visual force. Is the language selection in the same form as all other fields? – Zach Hutchins Jan 3 '20 at 14:03
  • The entire visualforce would be quite long. But yeah, the entire form is under 1 apex:form tag – vedant gupta Jan 3 '20 at 15:06

I also was unable to make this work, from the code that was provided as my base. So I went a different route that does a decent job and is supportable.

<apex:page controller="test" 
            <select id="languageSelection" onchange="changeLanguage()">
                <apex:repeat var="langCode" value="{!languages}">
                    <option value="{!langCode.Label}">{!langCode.Value}</option>
            <apex:pageBlock >    
                <apex:pageBlockSection title="My Content Section" columns="2">
                    <apex:inputField value="{!something.name}" required="true"/>
                <apex:pageBlockButtons >
                    <apex:commandButton action="{!save}" value="Save New Account Name"/>
        function changeLanguage(){
                window.location.href = 


public class test {
    public String language {get;set;}
    public Account something { get; set; }
    public List<SelectOption> languages {get;set;}
    public PageReference save(){
        return null;

    public testPdfController(){
        this.languages = new List<SelectOption>();
        this.languages.add(new SelectOption('French','fr'));
        this.languages.add(new SelectOption('English','en'));
        this.languages.add(new SelectOption('Spanish','es'));
        this.language = ApexPages.currentPage().getParameters().get('lang');
        this.something = [select id,name from account limit 1];      
        if(this.language == null){
            this.language = 'en';

    private void setDefaultSelectLanguage(){
        for(integer i = 0; i < languages.size(); i++){
            if(languages.get(i).getLabel() == this.language){
                SelectOption defaultOption = languages.remove(i);
                List<SelectOption> options = new List<SelectOption>();
                this.languages = options;
