Good Morning,

 We have been looking for a way to create a query on the contact screen to enhance the Opportunity Roles information.  We have created a VF page with tabs to display this information and both the page and extension work correctly in the sandbox. 

The relevant code for the VF page:

<apex:page standardController="Contact" extensions="OpportunityContactController" showHeader="true" tabStyle="contact" >

.

.

<apex:tab label="Donation Roles" name="OpportunityContactRoles" id="tabOppConRole">

         <apex:form >

              <apex:pageblock mode="edit" id="CustomList" title="Contact Roles"  >

                   <apex:pageBlockTable value="{!roles}" var="o" rendered="{!NOT(ISNULL(roles))}">

                       <apex:column value="{!o.OpportunityId}"/>

                       <apex:column value="{!o.Opportunity.Amount}"/>

                       <apex:column value="{!o.Opportunity.StageName}"/>

                       <apex:column value="{!o.Role}"/>

                       <apex:column value="{!o.CreatedDate}"/>

                   </apex:pageBlockTable>

                   <apex:outputLabel value="No records to display" rendered="{!(ISNULL(roles))}" styleClass="noRowsHeader">

                   </apex:outputLabel>

              </apex:pageblock>

         </apex:form>

      </apex:tab>

The controller class:

public with sharing class OpportunityContactController {

// the soql

  private String soql {get;set;}

  // the collection of contact roles to display

  private List<OpportunityContactRole> roles;

  public List<OpportunityContactRole> getroles()

  {

        return roles;

  }

  // the contact id

  private Contact ContId;

  public OpportunityContactController(ApexPages.StandardController controller) {

          this.ContId= (Contact)controller.getRecord();

      soql = 'SELECT Role, OpportunityId, Id, ContactId, opportunity.amount, opportunity.stagename, CreatedDate From OpportunityContactRole where ContactId = \''+ContId.Id+'\'';

      queryRole();

  }

    // runs the actual query

  public void queryRole() {

    try {

      roles = Database.query(soql);

    } catch (Exception e) {

      ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.ERROR, 'SOQL Error - Please contact your SalesForce Administrator'));

    }

  }

}

When we created a test for this extension, we get a "Constructor not defined" error on the underlined piece of code below.  The test class:

@isTest

private with sharing class TEST_OpportunityContact {

   static testMethod void myUnitTest() {

        //Add test data.

        Account a = new account (name='Test Account');

        insert a;

        Contact t = new contact (lastname='Test Contact', accountid=a.id);

        insert t;

        Campaign c = new campaign (name='Test Campaign');

        insert c;

        Opportunity o = new opportunity (name='Test Donation', campaignid=c.id, accountid=a.id);

        insert o;

        OpportunityContactRole[] ocr = new OpportunityContactRole[]{};

               for(Integer i = 1; i < 11; i++){

                       OpportunityContactRole r = new OpportunityContactRole (opportunityid=o.id, contactid = t.id);

                       ocr.add(r);

               }

        // Instantiate a new controller  - This where we get the error.

        OpportunityContactController controller = new OpportunityContactController();

        controller.queryRole();

        List<OpportunityContactRole> ocrs = controller.getroles();

        System.assertEquals(10,ocrs.size());

    }

}

I have tried several different iterations of the extension class and the test but cannot seem to find one that works, any ideas?

Thanks.
