Answer:
Text-edit-dialog-item is exported by text-edit-dialog.lisp.
If you don't load text-edit-dialog.lisp before you try to
create a text-edit-dialog-item, you'll need to unintern
the text-edit-dialog-item in the current package, since a
text-edit-dialog-item symbol has been created in the current package.

You can use the restarts menu to unintern the conflicting symbol,
or evaluate (unintern 'text-edit-dialog-item) in the current package.

Answer:
You don't need to change this. The code works correctly. When a subview is
active, the user can type in the text-edit field.

Basic-editable-text-dialog-item is not exported; it is internal to the ccl
package. If the text-edit-dialog-item is loaded, this should not be a problem
since the file is evaluated in the ccl package (in-package :ccl).
 
The following works correctly:

(in-package cl-user)
(load (choose-file-dialog :button-string "Load"))
(require 'text-edit-dialog-item)
(defparameter test-window (make-instance 'window
                            :view-subviews
                            (list (make-instance 'ccl:text-edit-dialog-item
                              :view-size #@(200 100)))))
