ess-display-help-on-object on lme4 will stop emacs about ess HOT 7 CLOSED

I cannot reproduce this. It probably has something to do with other
packages installed. Can you reproduce by only loading package lme4 in
clean R session? Do you set options(error=recover)?

thanks. when i remove '(ess-use-auto-complete (quote script-only)) from my dot emacs file. It works well.

But if i remove '(ess-use-auto-complete (quote script-only)) from my dot emacs file, I'll get another error:

1. open a R session
2. library(lme4)
3. type "lme4" then TAB which will call auto-complete (make sure auto-complete works)
4. an error with raised with error message :

from ess.

This problem is caused by mouse-avoidance-point-position function in the timer. So it is not related directly to ESS.

This looks like an emacs bug to me. I activated mouse-avoidance mode but cannot reproduce your error with emacs 24.3.50.1. What is the exact configuration for mouse-avoidance in your .emacs?

from ess.

R version 3.0.0 (2013-04-03) -- "Masked Marvel"
auto-complete: ac-version "1.4.0"

1. When I set ess-use-auto-complete to nil and mouse-avoidance-mode to nil, there will be no problem.
2. When I set ess-use-auto-complete to nil and mouse-avoidance-mode to animate, there will be only the error message about timer again and again, but will not hang emacs.
3. When I set ess-use-auto-complete to t and mouse-avoidance-mode to nil, it will hang emacs when lme4 loaded and type some command like "lme" and TAB.
4. When I set ess-use-auto-complete to script-only, and run ess-display-help-on-object (C-c C-v) before I load lme4, then it will be ok and no issues.

I think it may be related to the auto-complete.

I've been having the same problem for around 6 months now. Didn't want to submit it as a new bug.

ESS 12.09.2, EMACS 24.1.1.
As above, it works OK with
(setq ess-use-auto-complete 'script-only)
but hangs every time with
(setq ess-use-auto-complete 't)

This is the only package I've found with this problem. Thanks!

from ess.

Please upgrade. There will be soon 13.09 release. It's quite a big difference.
