Question

I am trying to Create Wizard for Custom Object

Here is my Apex Code:

public class Pageniation {
public FeedbackFrom__c Fed{get;set;}

 public FeedbackFrom__c getFed() {
      if(Fed== null) Fed = new FeedbackFrom__c();
      return Fed;
   }
    public PageReference step1() {
      return Page.Newtest;
   }

   public PageReference step2() {
      return Page.Newtest2;
   }

   public PageReference step3() {
      return Page.Newtest3;
   }
 public PageReference cancel() {
            PageReference FeedbackPage = new ApexPages.StandardController(Fed).view();
            FeedbackPage.setRedirect(true);
            return FeedbackPage; 
    }
public PageReference save() {

PageReference FeedbackPage = new ApexPages.StandardController(Fed).view();
      FeedbackPage.setRedirect(true);

      return FeedbackPage;
   }

}

       </apex:pageBlock>

Answer 1

You can use instance references in the Visualforce page, not the object type.

So when you do <apex:inputField id="myPicklist" required="true" value="{!FeedbackFrom__c.X2_Are_you_Satisfied_with_our_production__c}"/>, the visualforce page could not find any instance with name FeedbackFrom__c in the controller.

You have an instance named - fed which is of type FeedbackFrom__c, so you should use fed.X2_Are_you_Satisfied_with_our_production__c instead of FeedbackFrom__c.X2_Are_you_Satisfied_with_our_production__c.

What @itszmukeshy commented is correct, I just thought there should be an explanation.
