Wiki page edit buttons don't work with IE

[trac-ja@…]

Wiki page edit buttons (Preview, Merge and Save) don't work with IE7
(maybe, IE6 too).

These <input> elements don't have id attribute.

Update

It appears the id attribute has probably nothing to do with the problem (comment:4). Rather, IE seems unable to edit big wiki pages (comment:5).

Ummm, I encountered stack tracks and I cannot attach file….

Sorry, I can't reproduce the problem with IE7. Are you sure that your problem is related to the absence of "id" attributes? Btw, the "preview" id is already taken by the preview fieldset.

[trac-ja@…]

You are right, this is not relate id attribute.

But there is another that sometime wiki pages are not dipalayed.
Instead, IE7 displays "DNS Error" (as res://ieframe.dll/dnserrordiagoff.htm).

Sequence:

1. Access a Wiki page. (and login you need)
2. Push "Edit this page" button.
3. Push one of "Preview Page", "Review Changes" or "Cancel" buttons quickly or repeatedly.

I found this problem when Trac runs as tracd.
And I didn't encount Trac runs with cgi, fcgi, mod_python.

I think this problem causes IE7 or tracd's connection or session handling,
however I don't have any reasons.

[cboos]

Does that happen for big pages? For me, the limit is approximately 11933 bytes.
That problem is known but not really understood.
I think there's no ticket dedicated to that problem, so this one seems to be the place for tracking that problem.

Has any of you used ethereal or tcpdump to capture the session to see on a network level which side is the problem maker?

[cboos]

#2929 was similar, at least the symptoms described in that ticket are the same that what happens when trying to edit long wiki pages.

Works for me on ie7 and r6700
