Update isn't working on custom controller

Question

I need to be able to update ONLY the website and BillingAddress fields. As of right now I can't get any of the fields to update.

APEX:

public class AccountTypeController 
{
    public Account filterAccount{get; set;}
    public Account[] recordList{get; set;}
    public Account[] updateList{get; set;}
    public List <Account> acc {get;set;}

    public AccountTypeController()
    {
        filterAccount = new Account();
        recordList = new List<Account>();
        acc= Database.query('select Name,id from Account Limit 10');
    }


    public void updateRecordList()
    {
        recordlist = new List<Account>();
        recordList=[Select Name, Type, Website, BillingStreet, BillingCity, BillingState, 
                    BillingPostalcode, BillingCountry 
                    From Account Where Type = :filterAccount.Type];
          if(recordList.size()>0) 
          {
            filterAccount = recordList[0];         
          }

    }



    public pageReference save()
    {
        updateList = [Select ID, Name, Type, Website, BillingStreet, BillingCity, BillingState, 
                    BillingPostalcode, BillingCountry From Account 
                     Where Account.ID =:Apexpages.currentPage().getParameters().get('id')];
        try
        {
            update updateList;
        }
        catch(Exception e)
        {
            System.debug('Exception occurred ' + String.valueOf(e));
        }    
            return null;
    } 

}

VF:

<apex:page controller="AccountTypeController">

    <apex:form >

        <apex:outputPanel styleClass="requiredInput" layout="block" id="pwPanel">

            <apex:pageBlock title="Filter Accounts" mode="edit">

                <apex:pageBlockSection >

                    <apex:inputfield value="{!filterAccount.Type}" label="Account Type">

                       <apex:actionSupport event="onchange" action="{!updateRecordList}" rerender="pwPanel"/>

                    </apex:inputfield>
                    <br/><br/><br/>
                  <apex:outputPanel rendered="{!recordList.size > 0}">

                    <apex:pageBlockTable value="{!recordlist}" var="rl">
                       <apex:inlineEditSupport showOnEdit="saveButton"
                                               hideOnEdit="editButton" event="ondblclick"/>
                            <apex:column value="{!rl.Name}"/>&nbsp;
                            <apex:column value="{!rl.Type}"/>&nbsp;
                            <apex:column value="{!rl.Website}"/>&nbsp;
                            <apex:column headerValue="BillingAddress"
                            value="{!rl.BillingStreet} {!rl.BillingCity}, {!rl.BillingState} {!rl.BillingPostalCode} 
                            {!rl.BillingCountry}"/>

                    </apex:pageBlockTable> 

                   <apex:commandButton action="{!save}" id="SaveButton" value="Save"/>

                  </apex:outputPanel>

                </apex:pageBlockSection>

            </apex:pageBlock>  

         </apex:outputPanel>

    </apex:form>

</apex:page>

Answer 1

In your save() method, you are querying for a single account, based on a record Id in a URL parameter. There are a couple problems with this:

1. When you query the record(s), you are getting them as they exist in the database, without any of the changes the user might have made in the Visualforce page. It makes no sense to query records, just to save them again in exactly the form you just retrieved them, but that is what your save() method is doing.
2. You're working with a list of records in the page, but then only selecting one record in your save() method. You'd want to be saving all the records at once.

The records you're listing in your pageBlockTable are represented by the recordList variable you've declared in your controller. The {get; set;}, called the "getter" and "setter", allows the VF page to get the value of that variable to display it, and then also to set it when you call a controller method from an action attribute in the page. When you call the save() method from the button, data in your VF page that has setters will be updated in those variables, and then you can save it to the database. So your save() method can be:

 public pageReference save()
    {
        try
        {
            update recordList;
        }
        catch(Exception e)
        {
            System.debug('Exception occurred ' + String.valueOf(e));

        }    
        return null;
    }

One problem with this code is that the try/catch block has the effect of suppressing any error notification to the user, and only putting the error in the debug log. You should add an <apex:page:messages /> tag to the VF and then use addError() to let the user know.

Additionally, per this answer, you can't use <apex:column value="{!obj.fieldName}" /> with inline editing (even though it looks like it works). You have to use <apex:outputfield> inside the columns:

 <apex:pageBlockTable value="{!recordlist}" var="rl">
      <apex:inlineEditSupport showOnEdit="saveButton" event="ondblclick"/>
      <apex:column headerValue="Name">
           <apex:outputField value="{!rl.Name}"/>
      </apex:column>
      <apex:column headerValue="Type">
           <apex:outputField value="{!rl.Type}"/>
      </apex:column>
      <apex:column headerValue="Website">
           <apex:outputField value="{!rl.Website}"/>
       </apex:column>
       <apex:column headerValue="BillingAddress" value="{!rl.BillingStreet} {!rl.BillingCity}, {!rl.BillingState} {!rl.BillingPostalCode} {!rl.BillingCountry}"/>
 </apex:pageBlockTable> 

More generally: Salesforce StackExchange is not a good place to learn how to code on the platform. I don't mean to say that the community doesn't welcome beginners, because we absolutely do. But over the past couple of days, you've posted variations on the same code samples that display a real lack of understanding of the fundamentals, like how VF pages and controllers communicate. I strongly recommend heading to Trailhead, Salesforce's really excellent online learning platform, and working through the Beginner and Intermediate Developer trails. This should help you get some of these basic notions down. And if you get stuck, do some searching, check the docs and other resources that are linked from the Trailhead modules, and then feel free to come back here and ask some specific questions about where you're stuck.
