Missing Required Parameter 'from' for event 'open' - ERROR?

I upgraded to Snow Leopard the week it came out then encountered this last week. In my case it was an illegal file name. I took the # symbol out and viola, the file opened just fine. Change the file name and see if that takes care of your issue. It appears the UNIX naming convention is now being enforced.

common theme I'm seeing here is when I try to open files that contain art for #10 Envelopes. I tried changing the file name (removing the # sign), but that didn't help....

so, I'm now wondering if it's caused by files created by a "document preset" from a previous version of ID. I have many templates for standard size envelopes, business cards, etc that I use quite frequently and it seem this might be the culprit. most specifically #10s

can anyone else confirm this?

Same problem here with InDesign CS2

(MacBook 5,2. 4Gb Ram, plenty of HD space)

for what it's worth…

Symptoms:

similar to those described by other contributors.

History:

Rosetta in use for CS2, 10.5.8

1. previously experienced a number of InDesign CS2 crashes that (seemed) to be due to a problem .eps image in three series of files

    (ProjectX v.1, v.2 etc).

2. recovered those files, relinked to a backup of the .eps image and saved as...

3. all appeared ok, and this resulted in normally working files for two of the three version series. One series is still buggy.

Then 10.6:

4. Installed Snow Leopard 10.6 on top of 10.5.8 (cloned a copy of Leopard as backup).

    Rosetta installed. Snow Leopard and InDesign CS2 seemed to coexist well.

5. InDesign CS2 Message: Missing required parameter 'from' for event 'open'.

6. InDesign unexpectedly quits, often when opening affected file from within InDesign. machine state logs sent to Apple

Erased partition with (previously installed) Snow Leopard

Installed clean Snow Leopard with Rosetta option

Network and User info transferred from other partition (but not applications, to avoid messing up CS2).

Installed clean CS2 suite.

7. now, after the 'required parameter missing' message, clicked OK, InDesign CS2 generally doesn't crash.

8. When opening affected file from within InDesign, InDesign crashes before the file opens.

    Sometimes InDesign, when restarted, recovers the file automatically and it opens successfully.

    No twist or turn in save strategies solves this.

9.  Photoshop CS2 images only open from within the Photoshop CS2 dialogue....

10. Among much other information crash logs all show:

Exception Type:  EXC_BAD_ACCESS (SIGBUS)

Exception Codes: KERN_PROTECTION_FAILURE at 0x00000000000000c8

Crashed Thread:  0  Dispatch queue: com.apple.main-thread

Conclusions so far:

seems to relate on the one hand to relate to one particular series of files on one project (ProjectX v.1, v.2 etc) whether "saved as…" and/or renamed in Finder.

But a completely newly-created file with no text or images etc. still shows the Missing Parameter message and won't open. This is really peculiar.

The possibly corrupt image (1-3 above) does NOT, itself, seem to be part of the problem.

InDesign CS2 doesn't release the .idlk (edit locking file) after a crash which is probably normal.

The files which exhibit this bug in Leopard 10.5.8 and Snow Leopard 10.6 open fine in 10.5.7 on another Mac, (and used to open fine on the MacBook with Leopard 10.5.7).

I have experienced the same problem. I can tell you that it is not related to preferences, since I removed them and it still occurred. I also repaired permissions and tried rebooting in 32-bit mode with no effect.

I'm experiencing the same issue. After upgrading to Snow Leopard, some InDesign CS4 files open fine within Finder; others give me the error message "Missing Required Parameter 'from' for event 'open'." The files will open fine when opened within the application. I tried re-saving with a new file name but still get the same error message. I've filed a bug report with Adobe.

I think you should both file bug reports.

Adobe - Feature Request/Bug Report Form

Just upgraded to OS 10.6 and I'm getting that same weird error message when I open CERTAIN InDesign files by double-clicking on the icon.  Other files open okay.  Everything SEEMS to open okay when I open CS3 and go to FILE and OPEN.  Is this glitch on Adobe's radar?
