68145 - scrollbars.visible throws js exception on iframe

Status: VERIFIED DUPLICATE of bug 58539

(Core :: Layout: Images, Video, and HTML Frames, defect)

Description

[Cyril Elkaim]

Once security and privileges are enabled
the following code fragment throws an exception:

// enabling privileges. SEEMS to work OK
// I'm using signed.applets.... in the prefs.js file.
netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserWrite");
netscape.security.PrivilegeManager.enablePrivilege("UniversalBrowserRead");

// the two following cause exception:
top.frames["myframe"].scrollbars.visible=false;
// OR 
alert(top.frames["myframe"].scrollbars.visible);


Exception is -2147467259 nsresult 0x80004005 (NS_ERROR_FAILURE)

In general it seems that there are problems with scrollbars in skins for example
But you know for sure :-)

Tried with the 2001062021 build with the new xpconnect.
Apparently that works now. No more exceptions. BTW it's possible to have an
IFRAME with the SCROLLING="NO" parameter and be able to scroll with JavaScript.
Don't know if that's "legally" correct but, please, keep this behavior :-) as it
simplifies the code.

So for me this bug is VERIFIED

Thanks for the good work guys!
