Hopefully someone can help me out here. I have written the following code:

public with sharing class insertPatientProtocolSchedule {

//added an instance varaible for the standard controller

private ApexPages.StandardController controller {get; set;}

// initialize the controller

public insertPatientProtocolSchedule(ApexPages.StandardController controller) {

//initialize the stanrdard controller

this.controller = controller;

//Define Master Objects

Protocol_Arm__c pa = new Protocol_Arm__c();

Patient_Protocol_Record__c ppr = new Patient_Protocol_Record__c();

//Create a list of objects. Populate it with a query to the database.

list<Protocol_Arm_Activities__c> pactList = [SELECT Name FROM Protocol_Arm_Activities__c WHERE Protocol_Arm__r.Id = :ppr.Protocol_Arm__r.Id];

//Cycle through the list, and for each object create a new one, the only difference being the MasterId

list<Protocol_Arm_Activities__c> NewList = new list<Protocol_Arm_Activities__c>();

for (Protocol_Arm_Activities__c paa : pactList) {

Patient_Protocol_Activity__c ppa = new Patient_Protocol_Activity__c();

ppa.Name = paa.Name;

ppa.Patient_Protocol_Record__c = ppr.Id;

NewList.add(ppa); // Error Line

}

// insert new records

insert NewList;

}

// method called from the VF's action attribute to clone the schedule

public PageReference addSchedule() {

}

And I am getting the following Error In Eclipse on the line I have marked with //Error Line:

Save error: Incompatible element type SOBJECT:Patient_Protocol_Activity__c for collection of SOBJECT:Protocol_Arm_Activities__c

I am not seeing any issues.

Both Patient_Protocol_Activity__c and Protocol_Arm_Activities__c are the Detail in a Master-Detail relationship.

Thank you for any help you can provide.
