Parent object is not available in a script to hide a New button on a form's related list in a scoped application

1. Create a scoped application.

2. Create a parent table in the scoped application.

3. Create a child table in the scoped application.

4. On the parent table form, define a related list using the child table.

5. Edit the List control for the child table records as follows:

   var answer;
   if(parent.active == 'true'){
      answer = true;
   }
   else{
      answer=false;
   }

6. Refresh the parent record and then view the localhost log.

   Example entry found in the log:
