Standard Navigator Buttons
Regardless of which callbacks are defined for a dialog, all standard NX dialogs have an Ok, Apply, and Cancel button. The standard behavior of these buttons is:
- Ok — Execute an Apply action using the current dialog values and exit the dialog.
- Apply — Execute the dialog actions using the current dialog values, then reinitialize the dialog for a new edit or create.
- Cancel — Exit the dialog without taking any further actions.
To ensure standard behavior the Apply callback is required. Furthermore, the template code for the Ok callback will include a call to the Apply callback.
Note: If you do not generate an Ok callback then NX will execute your Apply callback automatically when the Ok button is hit.
