thanks everyone~
additional to a 'g' shortcut key is work fine.

i know kill-buffer is not appropriate in this situation,
but I define shortcut key 'f2' -> kill-this-buffer.
and I have a habit use f2 to close current window buffer. 
 RET-->open heading buffer--> make change --> f2 kill-buffer,
and return the org-agenda view.

error occur in this case.

thanks.

I can't reproduce this with the standard agenda view on Org-mode version
7.5 (baseline.265.gcfb05)
If it requires the custom agenda view to reproduce, you have to provide that.
What version of orgmode are you using? See section 1.4, "Feedback", of the
manual on how to report a bug.
