Here is what the page does:
1. Page allows user to set case bucket, subject, due date and description
2. User clicks a button to save and add attachment. The model assigns the case to a queue and inserts the record.
3. A pop-up appears with a file upload component
4. User can upload a document that attached to the record. File is uploaded as attachment to the case record.
If the user uploads a PDF Skuid will change the ownership from a queue to our default case user.
If I use native SF to this it does not change the owner.
