In the previous chapters, we have gone through some examples of how to save data. We used Form submit, Ajax request, and also the writing resource from the store. In this chapter, let's focus on the functionalities we have not implemented yet. But don't worry, the complete implementation is available in the source code distributed with this book.

This is also useful because we have a CheckBox group, and it can be a little tricky to load their values on the Form panel.
