/**
* file uploading issue:
*
* When processing sub-actions, the file objects are shared across the
* parent action. sometimes the column name will collide with the parent action column names.
* To solve this issue, we have to separate the namespace.
*
* solutions:
* 1. the file upload object should be action-wide not request-wide
* 2. save the file upload object in the action, not in the request object.
* 3. do not access $_FILES or request->files directly.
*
* plan:
* 1. Moved uploadedFile access methods from ActionRequest to Action itself.
