"Page not modified" exception is disturbing and counter productive

[alexandre.franke@…]

When a user clicks on Submit changes on a wiki page that has not been modified, he gets a page with an agressive red error square that says "Page not modified".

Here at my work, we already had several users that got lost when facing this.

What would be better would be to have the page (that was being edited) displayed with a warning square prepended saying "No changes have been made, page displayed below as it was before editing" or something similar.

The message "No changes have been made" could be displayed in kind of warning box, similar to the version info box.

Replying to cboos:

The message "No changes have been made" could be displayed in kind of warning box, similar to the version info box.

What is really important is that users shouldn't face a dead end when submitting an unchanged page. Warning them that the page is the same is ok but there really should be either the submitted page under the warning or a link that says "Go to page" because currently users see the error page and are blocked facing it. They think they are punished even though they did nothing wrong.

To sum up, the behaviour when submitting an unchanged page should be the same as when cancelling its edition.

So I think a good compromise would be to show the page in the versioned mode, so that it's evident that nothing changed after the edit and at the same time, there's no special error or warning...

Fixed like that in r4796.

In [7034], I finally also added an explicit warning.
