linum with nxhtml can't work properly

[Lost shen]

when i opened a php&html mixed file, i will get this message
"Toggling linum-mode off; better pass an explicit argument."
but linum works well in this time, and when i move cursor to php chunk, line-number disappear and get the warning
again, continue move the cursor, line number will appear and when move out php chunk, it will disappear again.
how can i deal with it ?

GNU Emacs 23.2.1 (x86_64-apple-darwin, NS apple-appkit-1038.29)

Thanks Lost shen,

This is an Emacs bug. I have just filed an Emacs bug report for it:

 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=6871

[Lost shen (jayklx)]

I commented this line in linum.el
 (add-hook 'change-major-mode-hook 'linum-delete-overlays nil t)
it works good now.
will it bring me any side-effect?

[Lost shen (jayklx)]

I try to use mmm-mode for a test, linum works well with it ,so, i think its not a linum bug, mumamo-mode would be have something conflict with linum-mode.

[lborgman (lennart-borgman)]

It sounds very strange that this bug does not show up in mmm-mode. Does it really handle major mode dependent minor modes at all then?

[Lost shen (jayklx)]

yah,its strange, although mmm-mode works with some bugs(indent and font-lock incorrectly etc) but it really change major mode when move between different chunks,and linum just work well.
i think there's not only one hook make linum update lineumber, because,after i comment out
 (add-hook 'change-major-mode-hook 'linum-delete-overlays nil t)
it also make a little change with linenumber,it display wrong line number first time to enter a different chunk, and works well after that.
you can test it with:
1.comment out the line above;
2.turn on global-linum-mode;
3.edit a mixed file ,like php+html,
and move the cursor form html chunk to php chunk, you'll see what happend.
my English is not well, hope you can understand what i mean :)

Lost shen,

If you look at the Emacs bug report that I sent (see above) you can find a patch for linum.el there that fixes the problem. A version of this will be applied to Emacs (when I have time to fix it).

[Lost shen (jayklx)]

thanks for your job.
but, i tried to apply the patch by Lennart Borgman,
it not work, Lennart Borgman post two patches,but neither seem to work properly.
if you give it a try, you'll know whats wrong.
anyway, thanks for your patient to deal with this bug, and give us such an amazing nxhtml.
i'll still wait for a solution.
this bug is not such important, but for a perfect emacs. you need'nt take much time of it if you
are busy.

[Lost shen (jayklx)]

hha, seems Lennart Borgman is you...
sorry for my mistake..

[Lost shen (jayklx)]

use your patch (the full one) and add this to .emacs

(add-hook 'find-file-hook (lambda () (linum-mode 1)))

its seems perfect now~

[lborgman (lennart-borgman)]

This is fixed in my patched version of Emacs+EmacsW32, but the patch is not applied to Emacs yet. So this is not a bug in nXhtml. Closing.
