I have a controller extension which takes a StandardSetController. I have a list button on the Account list view.

And I am using person accounts. 

One of the fields in my view filter is based on a Contact field. But since it's a PersonAccount it shows up under the Account filters, as it should.

However when I call the getSelected() method in my controller I get the following error:

"core.apexpages.exceptions.ApexPagesHandledException: Object type not accessible. Please check permissions and make sure the object is not in development mode: and (Level__r.Name = 'Intermediate'))) ^ ERROR at Row:2:Column:6 Didn't understand relationship 'Level__r' in field path. If you are attempting to use a custom relationship, be sure to append the '__r' after the custom relationship name. Please reference your WSDL or the describe call for the appropriate names." 

This makes perfect sense as the relationship should be Level__pr and not Level__r. But all this is happening in the getSelected() method which is a Standard method on the StandardSetController, So I have no access in order to properly format the query. This seems like a bug in SFDC to me.

Any suggestions? Preferably from somebody in SFDC tech support?

Here's a snippet of the code

public with sharing class StudentCourseBuilderController {

    private ApexPages.StandardSetController setcontroller;


    public PageReference bulkLoad() {
        List<Account> asts = setController.getSelected(); // FAILING HERE
        if(asts == null || asts.isEmpty())
            return null; //asts = [select id from Account limit 3];
        List<Contact> csts = [select id, accountId, internal_id__c, firstName, lastName, 
                    (select course_id__c from Course_Details__r order by course_id__c desc limit 1)
                    from Contact where accountId in :asts];
