Status: VERIFIED WORKSFORME

(Firefox :: General, defect)

Description

[Martijn Wargers (dead)]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6a) Gecko/20031021 Firebird/0.7+
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6a) Gecko/20031021 Firebird/0.7+

See the testcase coming up.

I have a midas rich editor, and I have a function who does the basic cut,copy,
paste operations:
netscape.security.PrivilegeManager.enablePrivilege('UniversalXPConnect');
y.contentWindow.document.execCommand(f, false, null);

So you get first a warning if you want to allow UniversalXPConnect privileges
for this page. If you allow this, it should cut,copy and paste.
This works in Mozilla, but not in Firebird. I get an exception there:
Error: uncaught exception: [Exception... "Component returned failure code:
0x80004005 (NS_ERROR_FAILURE) [nsIDOMNSHTMLDocument.execCommand]"  nsresult:
"0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame ::
file:///C:/cutcopypaste.htm :: doe :: line 16"  data: no]


Reproducible: Always

Steps to Reproduce:
1.See testcase
2.
3.

Actual Results:  
I got an error. See above

Expected Results:  
Do the same as Mozilla

confirming
this really only seems to affect the cut/copy/paste, since every other midas
command works. I've uploaded the midas demo, but here it gains the privileges
with xpconnect instead of the prefs at the orginal demo. You can find it at

blake: any chance looking into this? imo midas is quite important for corporate
users

What version of firefox?

This works for me in Firefox 0.9.2 (if I save the file locally)

Comment 5

[Mike Kaply [:mkaply]]

Didn't realize how old the bug was.

This works in current Firefox.
