Summary: tinyMCE is lacking a unload handler (as already
described in the tinymce todo list)
Product: Lenya
Version: 2.0
Platform: Macintosh
OS/Version: All
Status: NEW
Severity: normal
Priority: P3
Component: TinyMCE Integration
AssignedTo: dev@lenya.apache.org
ReportedBy: ragaller@apache.org
Currently tinyMCE can be exited by clicking any link outside the editable area. This can
lead to data loss and always leads to a locked page (force checkin has to be used).

i've read the patch, and it looks very good and in keeping with tinymce coding
style. however, i'm wondering:
tinymce has this issue because it tries to provide true wysiwyg in-place editing.
this capability might be highly desirable for other editors, too.
maybe we could implement a generic onunload() handler that will run an
editor-specific callback if provided (similar to the way richard implemented the
backspace catcher in an editor-agnostic way).
what does an onunload() handler need to do?
* catch the onunload event and prevent leaving the current page.
* provide a message that informs the user of unsaved data and allows to "leave",
"save and leave", "return to editor".
"leave" must remove the lock on the document and then execute the previously
caught navigation event.
"save and leave" will have to signal the editor (invoke its save callback) and
then navigate away.
"return" just eats the unload event and return to the editor.
wdyt?

Another big + for the idea. The problem with document.onbeforeunload is, that it
triggers a predefined screen that can only partially be modified. It would be
very nice to have the three options you described - but I did not find a way to
display and process a custom screen on an onbeforeunload event. Maybe there is a
better way to do the event handling than using window.onbeforeunload.

the attached patch show a possible approach
It is still in a raw form and is meant as an illustration of concept - please
do not apply as is.
