If you edit some text in-line in that PageFlow sample, and then click on the “Save” button, doesn’t the new text show up in the JSON representation of the model in the textarea?
Or if you just edit the text in that textarea and then click on the “Load” button, don’t you see the modified text, or a completely different flow, depending on what changes you made to that JSON text? (You can also end up with no changes or nothing if you change it to become syntactically invalid JSON.)
Or do you mean that when you reload the page the sample starts off the same each time? That’s intentional – there’s no database anywhere that the samples utilize. If we make improvements to a sample, we want the user to see the latest. Some of the samples do load data from our server, but it’s going to be the same each time, for exactly this reason.
