How to update related object fields?

I'm trying to update fields of a custom object along with fields of a related object. The fields of the primary object are updated without a problem, but none of the related object fields are updated. Notice that the saveRecord() method calls update on both objects. How can I accomplish this?

 

Visualforce:

 

<apex:page showHeader="false" standardController="PrimaryObject__c" extensions="controlEntity" sidebar="false" standardstylesheets="false">

    <apex:form>
        <div>
                <apex:inputField value="{!PrimaryObject__c.Name}" />

                <apex:commandButton action="{!saveRecord}" value="Save"/>

                <apex:inputField value="{!PrimaryObject__c.LookupField__r.Name}" />
                <apex:inputField value="{!PrimaryObject__c.LookupField__r.Address__c}" />
                <apex:inputField value="{!PrimaryObject__c.LookupField__r.City__c}" />
                <apex:inputField value="{!PrimaryObject__c.LookupField__r.State_Province__c}" />
                <apex:inputField value="{!PrimaryObject__c.LookupField__r.Zip_Postal_Code__c} " /> 
                <apex:inputField value="{!PrimaryObject__c.Email_1__c}" />
                <apex:inputField value="{!PrimaryObject__c.Email_2__c}" />
                <apex:inputField value="{!PrimaryObject__c.Phone_1__c}" />
                <apex:inputField value="{!PrimaryObject__c.Phone_2__c}" />
                <apex:inputField value="{!PrimaryObject__c.Inactive__c}" />
        </div>
    </apex:form>

</apex:page>

 

 

Extension class:

 

public with sharing class controlEntity {
    public PrimaryObject__c entity;
    public RelatedObject__c contact;
    
    public controlEntity(ApexPages.StandardController controller) {
        this.entity = (PrimaryObject__c)controller.getRecord();
        this.contact = [SELECT Name, Address__c, City__c, State_Province__c, Zip_Postal_Code__c FROM RelatedObject__c WHERE Customer_Vendor__c = :ApexPages.currentPage().getParameters().get('id')];
    }
    
    public PageReference saveRecord() {
        update entity;
        update contact;
        return null;
    }
 }

 Thank you.

In your code you are not filling new information in to child objects, you have to do it explicitely like below..

public with sharing class controlEntity {
    public PrimaryObject__c entity;
    public RelatedObject__c contact;
	public public ApexPages.StandardController SC ; // standard controller instace
    
    public controlEntity(ApexPages.StandardController controller) {
		SC = controller; // assign standard controller reference
        this.entity = (PrimaryObject__c)controller.getRecord();
        this.contact = [SELECT Name, Address__c, City__c, State_Province__c, Zip_Postal_Code__c FROM RelatedObject__c WHERE Customer_Vendor__c = :ApexPages.currentPage().getParameters().get('id')];
    }
    
    public PageReference saveRecord() {
        update entity;
		
		PrimaryObject__c rec = (PrimaryObject__c) SC.getRecord();
		contact. Address__c = rec.LookupField__r.Address__c;
		contact.State_Province__c = rec.LookupField__r.State_Province__c;
				.
				.
				Do this for all fields
				.
				.
			
		
		
        update contact; // update contact
        return null;
    }
 }

Thank you immensely Shiv.

 

A few minutes before I read your answer, another solution occurred to me which also works perfectly: adding the following line to saveRecord():

 

update entity.LookupField__r

 

Do you see any potential weaknesses with this approach?
