<h2>Things to notice</h2>
|
|
<ul>
|
|
<li>Cancel & save buttons are only enabled if the form is dirty — there is something to cancel or
|
|
save.</li>
|
|
<li>Save button is only enabled if there are no validation errors on the form.</li>
|
|
<li>Cancel reverts the form changes back to original state.</li>
|
|
<li>Save updates the internal model of the form.</li>
|
|
<li>Debug view shows the two models. One presented to the user form and the other being the pristine
|
|
copy master.</li>
|
|
</ul>
