Item5178: 'Please wait message' is entered into Editor's undo-history

The transition from Please wait... retrieving page from server to the actual topic text is part of the editor's undo-history, while it should not.

I don't think so. The transition is under the control of Javascript, and is not cached. What you are probably seeing is that the onload handler is caled when the page in the history is re-visited, resulting in a request sent to the server to convert the TML into HTML for editing. That's the way it is supposed to work. If you are seeing something else, please be specific. For example, do you see the wrong content when navigating "Back" to the page?

I can confirm this bug report.

Mark description is easy to reproduce.

Click Edit on any topic and wait for the TMCE to load and be fully loaded.

Edit some text.

Hit the undo button in the button bar several times.

Note how the editing you did is undone. And then finally - as Mark describes - you end up with "Please wait... retrieving page from server".

Save and your topic is lost.

Can be reproduced both in FF and IE by just following Marks bug description. I do not understand that you cannot see this Crawford.

When the page is loaded the undo history should not include the "Please wait..." message.

Undo should be greyed out when page is loaded and not active until you have typed something.

And when you undo multiple times the last undo should be the one that brings you back where you started - and not the "Please wait..." message.

Sorry, I misread the report. I thought he meant the browser undo histoyr (aka the back button), not the editor undo history.

I can no longer reproduce the behaviour that Mark reported. My installation is at revision 3794. I observed a new problem, Item1549, which may be related.

It probably is related. The undo history is under the control of TinyMCE, and if it chooses to store the conversion in the undo history, I'm not sure there's anything we can do about it. Anyway, follow up in Item1549 - this is No Action now, as Michael states.
