193933 - Zope External Editor no longer works; this got broken in between 1.3a and 1.3b.

Status: VERIFIED FIXED

(Core Graveyard :: Plug-ins, defect)

Description

[Feneric]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US; rv:1.2.1) Gecko/20021130
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US; rv:1.3b)

Many Zope sites employ the Zope External Editor product.  It enables users to
click a pencil icon and have the target file pop up in their editor of choice
via the wonders of MIME types (it uses the dummy MIME type
"application/x-zope-edit" to do its work), WebDAV, and a Python applet.
With Mozilla versions 1.3a and earlier, everything just works.  With version
1.3b,  it fails and pops up a dialog stating that perhaps the file should be
downloaded first.
The Zope External Editor product works on WinTel and UNIX boxes in addition to
Mac OS X; I don't know if those other platforms are also affected or not.

Reproducible: Always

Steps to Reproduce:
1. install Zope External Editor on your test machine
2. click a pencil icon on a Zope site with Zope External Editor capabilities
3.

Actual Results:  
The system tries to download the target file and fails to open an editor

Expected Results:  
run the ZopeEdit Python applet to open the target file in an appropriate editor
via WebDAV

Is there a mime type in your helper app settings in the prefs?

Where can I download Zope External Editor?

> Is there a mime type in your helper app settings in the prefs?

Yes.  The MIME Type:

	application/x-zope-edit

should be handled by:

	Macintosh HD:usr:local:bin:ZopeEdit

(or wherever the ZopeEdit applet has been installed on your system).

> Where can I download Zope External Editor?

The Zope External Editor lives at:

	http://www.zope.org/Members/Caseman/ExternalEditor/

In addition to being downloadable from there, the site also has a fair amount of
documentation on how it works, how it can be installed, and how it can be
configured.  Generally Mac OS X follows the UNIX conventions listed.  The only
gotchas with installing it on Mac OS X are:

1) You need Tcl/Tk installed.  Mac OS X has Tcl pre-installed, but not Tk.

2) You need Tkinter installed for your Python installation.  Mac OS X Python
doesn't have this by default (of course, since it doesn't have Tk by default).

I don't have any public Zope sites with External Editor enabled; I'm pretty sure
though that the main Zope CMF Dogbowl:

	http://cmf.zope.org/

supports External Editor and offers free registration and thus should provide a
pretty good testing ground.

I don't know if 1.3a -> 1.3b broke Zope External Editor for all Mozilla
versions, or just Mac OS X.  Zope External Editor is in pretty heavy use in the
Zope community not just with OS X but with MS-Windows and UNIX as well.

I'm sorry to have found a bug without having more idea of its scope or even a
clue as to a solution...  I must confess that although I try to use the most
recent version of Mozilla for all my day-to-day work, the combination of this
bug and bug 181293 have forced me to revert to 1.1.

if you remove the mime type from the helper app settings, does the prompt to
open/save appear? If you then select the right application, does it open correctly?

It looks like I've got egg-on-face...  by clearing away Mozilla's MIME types and
resetting them under 1.3b it appears to now work in 1.3b...  whatever changed
between 1.3a and 1.3b didn't break Zope External Editor, it just (apparently)
required that the MIME type for it be removed and recreated. It's funny because
I've been using Zope External Editor since the early 1.1 days and it's always
just worked with each upgrade through 1.3a.

Thanks for your help.
