I have a page that iterates a list object to display the records. Once clicked on save, I updated the same list with new values and debug logs shows the update list but output panel is not rerender'ed and I dont see updated list on VF page.

<apex:outputLabel >A  </apex:outputLabel>
        <apex:inputfield id="idAText" value="{!ttlookup.A}" />
      <apex:inputCheckbox id="checkBoxTMId" value="{!Acheckbox}"/>
      <apex:outputLabel > Check if you want to clear all values 

    <apex:commandButton id="btnSave" value=" Save " action="{!Save}" reRender="idPanel" />

 <apex:outputPanel ID = "idPanel">
        <div class="container">   
                        <apex:repeat value="{!ryList}" var="tt">

Controller code:

 public void save(){
    Boolean noUpdateFlag = false;
    for(MyObjec ttry: ryList){
        if(ttlookup.A !=null){
            noUpdateFlag = true;
            ttry.name = ttlookup.A;

            noUpdateFlag = true;
            ttry.name = null;

    system.debug(ryList[0].B + ' noUpdateFlag '+noUpdateFlag);
            update ryList;
            ApexPages.addmessage(new Apexpages.message(apexpages.severity.CONFIRM, 'records are saved.'));
            ApexPages.addmessage(new Apexpages.message(apexpages.severity.Info, 'no value entered '));
    }catch(Exception ex){
        ApexPages.addmessage(new Apexpages.message(apexpages.severity.Error, 'Something went wrong'));


and moreover when I add reRender = "id.." my apex messages are not displayed. I have no clue why :( any inputs please?

VF page code looks good. Rerender should work properly. It looks like you are not updating the list. So please update the list in a proper way and check the result.

  • I was update it but It contains only ID not the name so I had to query and update the list by name and type. It worked now. It strick my mind when you commented that I might not have updated the list. Thanks @Pragati Jain
