Trailhead Creating and using Custom Controllers Challenge Issue

I'm getting the error "The outputLink component is not binding to the ID of a case" for this challenge. I've checked several threads on here and I'm almost certain it should be correct. It does link to the details page for the case. 

I initially just had the ID linking but have changed it so both case number and id link via id in case that mattered. 

I've also previously tried having a complete url as the value but no luck. 

Any help would be appreciated.

<apex:page controller="NewCaseListController">
 
        <apex:pageBlock title="New Case List" id="cases_list">
            
    <apex:repeat value="{! newcases }" var="cases">
       
        <apex:outputLink value="/{! cases.id}">
        ID:  {! cases.id }
        </apex:outputLink><br/>
        <apex:outputLink value="/{! cases.id}">
        Case Number:  {! cases.CaseNumber }
        </apex:outputLink><br/>    
    
    </apex:repeat>
            
        </apex:pageBlock>

Try with variable name "Case" instead of cases.



<apex:repeat var="case" value="{!NewCases}">

Hello Ronan O'Neill,
Can you paste here Controller Code..
I am trying with below code its working fine..
Vf:-
<apex:page controller="Test">
<apex:pageBlock >
    <apex:outputLink value="/{!c.Id}" >Back</apex:outputLink>
</apex:pageBlock>
</apex:page>

Controller:-

public with sharing class Test { public Case c {get;Set;}     public Test(){         c = [select id from case limit 1];              } }

Thanks..

My controller code 

public class NewCaseListController {
  
    public List<Case> getNewCases() {
               
        List<Case> results = Database.query(
            'SELECT id, CaseNumber ' +
            'FROM Case ' +
            'WHERE Status=\'New\''
        );
        return results;
        
    }

}

But just to stress, its the Challenge check on the Trailhead that is failing with the message "The outputLink component is not binding to the ID of a case". The page loads fine for me and the links do redirect to the case details page.

Yep, That got it. Thank you very much. I was apparently blind to that extra s.

I don't have html experience so it took me a bit of time to get the ;syntax correct reading through the different threads.
The following passes the challenge:

Hope this helps.

The VF page: 
<apex:page controller="NewCaseListController">
	<apex:form >
    
        <apex:pageBlock title="New Case List" id="cases_list">
        
        <apex:repeat value="{! newcases }" var="case">
        	<p><apex:outputLink value="/{! case.Id}">{!case.CaseNumber}</apex:outputLink></p>
        </apex:repeat>
      
    </apex:pageBlock>
    
    </apex:form>

</apex:page>

The controller: 
public class NewCaseListController {
    public List<Case> getNewCases() {
        List<Case> newCaseList = Database.query('Select Id,CaseNumber ' + 
                                                'From Case ' + 
                                                'Where Status=\'New\''
                                               );
        return newCaseList;
    }
}

Just saw this. FYI you don't need the form tags in your visualforce page as your not submitting any records. I can't get this challenge to work :(
InesGarciaInesGarcia
Alrighty,

After speding quite a bit of time on this myself.

1. The repeat component needs:Value, Var and ID. 
2. Filter on New to 'WHERE Status = \'New\' '

So thats is how would work and pass the badge:

VISUALFORCE PAGE NewCaseList 
<apex:page controller="NewCaseListController">
    <apex:form >

        <apex:pageBlock title="New Case List" id="cases_list">

            <apex:repeat value="{!newCases}" var="case" id="case">
                <p><apex:outputLink value="/{!case.Id}">{!case.CaseNumber}</apex:outputLink></p>
            </apex:repeat>

        </apex:pageBlock>

    </apex:form>

</apex:page>


CUSTOM CONTROLLER NewCaseListController 
public class NewCaseListController {

    public List<Case> getNewCases() {
        List<Case> results = Database.query(
            'SELECT Id, CaseNumber, Status ' +
            'FROM Case ' +
            'WHERE Status = \'New\' '
        );
   
    return results;
    }

}


​Tada!

I have follow the steps that have been laid out in this thread. I continue to get this error message.

Challenge Not yet complete... here's what's wrong:
There was an unexpected error in your org which is preventing this assessment check from completing: System.QueryException: unexpected token: Status

What is the logic for add the \'NEW\' ' for status instead some else like  ' Status = "NEW" ' ?

Help and Clarification welcomed

I was having issue with the challenge not meet with errors complaining about the custom controller not working, even though a test case showed otherwise and the page rendered correctly.  Ines's soltuion did work for me.  Many thanks Ines for posting it.

Guys, i got the following code to work: VSF
<apex:page  controller="NewCaseListController">
    
   <apex:repeat value="{!NewCases}" var="case" id="case">
       <apex:outputLink value="{!case.id}"/><br/>
       
    
    </apex:repeat> 
</apex:page>

AND 

Apex class:

public class NewCaseListController {
    
    public List <Case> getNewCases(){
        
         List<Case> results = Database.query(
        'SELECT Id, CaseNumber, Status ' +
        'FROM Case ' +
        'WHERE STATUS =\'New\'' 
         );
             return results;

}
}

make the links open to the page:
  
<apex:outputLink value="{!urlfor($action.case.view,case.Id)}">{!case.caseNumber}</apex:outputLink>

 
Rich FiekowskyRich Fiekowsky
This works (the links open the Case records) if you code as Steve Clarke does,
<apex:outputLink value="{!urlfor($action.case.view,case.Id)}">{!case.caseNumber}</apex:outputLink>
however the Challenge fails.
Coding instead 
<apex:outputLink value="{!case.Id)}">{!case.caseNumber}</apex:outputLink>
passes the Challenge, but, the links fail (on my system at this time); they display a page which only contains the message "The name can only contain underscores and alphanumeric characters. It must begin with a letter and be unique, and must not include spaces, end with an underscore, or contain two consecutive underscores. " Since a previous unit used the URLFOR($Action... technique in this situation, perhaps the challenge evaluation may be at fault here.

Hey everyone, quick question about binding on the <apex:repeat> and the binding "{!NewCases}". How does the naming work here? Can we make the binding whatever name we want, or is it whatever follows the "Get" i.e. GetBindingName()?
