When you have a network failure and you push on save, all contents is lost. Using the back doesn't give any info.

In the raw edit mode, it is possible to use the back button and then you have your information back, which you can try to save again or copy to something else.

Wouldn't it be better to make some kind of check if network is ok before saving.

This can be easily reproduced by disconnecting your PC from the network

Was this is Firefox?

There is a known issue with going back in the browser in Firefox - in TinyMCE mode.

No it wasn't. It is Internet Explorer version 7

-- TWiki:Main.FrederikBeun - 30 Nov 2007

When you go back, there is a javascript error in the guts of Tiny MCE (something to do with an access violation accessing the document when adding event handlers)

Unfortunately IE doesn't give much information frown

This does not affect stored data, obviously enough, but large edits can be lost this way.

Corrected the summary line. Only changes are lost.


I cannot reproduce this. Just tested with IE 7:

  1. Started an edit with TinyMCE
  2. Unplugged the internet cable
  3. Clicked Save
  4. After a timeout, Explorer gave me the page "Internet Explorer cannot display the webpage"
  5. Reconnected the cable
  6. The editor window says "Retrieving page from server"
  7. ... but it showed my changes as well
  8. Saving and all is well
The same happened when going to Preview first and then disconnecting.

Indeed the solution is you need to go back when the connection is there again, otherwise it shows the Retrieving page from server remark. When network is back and you push then on refresh page, then you loose everything. But if you instead you go back and then forward on the browser you get everything back.

How can we make this clear to the users?

I don't know. It's not something that is easy to explain.

I am very tempted to set this as "Normal", but I leave it to the release manager's judgmenet (that's why we have release managers, after all:-) )


I am used to in web applications that if you submit to a disconnected network and then hit refresh it is good bye to anything to entered.

But going back and resubmitting should work. If this is the case then there may not even be a bug.

If this does not work then it is the general going back that is broken.

That should be fixed.

But a fix is not within a few days reach so I lower to normal. We can release with this. Especially because TMCE is a plugin that can - AND WILL FOR SURE - be updated many times the next months.
