BlairB Need help with passing parent ID to child record and assigning record type
Hi,
I am attempting to create a visualforce page that will be accessed from a button on a related list. This button will allow users to add multiple child records related to the parent record.
The parent object is Sessions__c and the child object is Class_Enrollments__c. I want users to be able to click the button and be routed to a VF page where they can add child records on one page.
I am running into three issues:
1) Whenever I try to save the record, I get the following error:
System.DmlException: Insert failed. First exception on row 0; first error: REQUIRED_FIELD_MISSING, Required fields are missing: [Session]: [Session]
Error is in expression '{!insertClass_Enrollments}' in component <apex:commandButton> in page add_class_enrollments: Class.AddingEnrollmentsController.insertClass_Enrollments: line 14, column 1
Class.AddingEnrollmentsController.insertClass_Enrollments: line 14, column 1
So, the parent record ID is not being passed to the child records.
2) I want to assign the record type ID to new child records. Child records will have the same record type for this particular page/button.
3) The "Delete" row function is not working
Below is my controller extension:
VF page:
Finally, all of this is being accessed via a list button that has the following URL:
/apex/Add_Class_Enrollments?SessionId={!Class_Enrollments__c.SessionId__c}
Help appreciated!
