OWA – ‘gtLV’ is null or not an object

// July 15th, 2010 // No Comments » // Exchange 2007, Internet Explorer, Scripts, Web Applications

I was getting the “gtLV’ is null or not an object” message when I replied to an email using our Microsoft Online Hosted Exchange email account. Ironically enough, the problem would always occur when I replied to a new email from a Microsoft support engineer. The email would go through but I would get the “ ’gtLV’ is null or not an object” error message popup on the screen. If I replied to the email again the problem would not occur. A very similar message can be seen in the Microsoft Exchange Server forums where I also posted the provided solution.

After many emails to the very patient support tech at Microsoft (as I would reply and then send an email to let him know if the reply worked or not) we escalated the ticket and I got back the following resolution.

1. type regedit on command prompt or run
2. go to: HKCU\Software\Microsoft\Internet Explorer\Main
3. create TabProcGrowth (string or dword) and set the value to 0

This solution worked for me.  From what I can see at the ie8blog this has the side effect of reducing the protectedmode protection and I think the browser tabs use the same process rather than running in seperate processes.  This is a slight downside, but I doubt many users will care – they’re more than happy to have OWA working.

KnowledgeTree Dropbox

// April 15th, 2010 // No Comments » // Web Applications


In certain environments, after an upgrade to KnowledgeTree 3.6.x, an issue with permissions on the “var” directory and sub directories results in the following exception error:
<ErrorReport Project=”BaobabClient”> <UserReport Short=”Exception found [mkdir() [<a href=’function.mkdir’>function.mkdir</a>]: Permission denied].”>

This also applies to a problem while uploading a document when the message “Initializing, please wait …” appears at the “Metadata Capture” screen and  the permission denied message when connecting Dropbox to your KT url.

To resolve this issue, check the following:

1. The user running the apache server should have correct permissions on the following folder and sub folders: <KnowledgeTree Directory>\var

2. Navigate to DMS Administration > System Configuration > General Settings > Urls > Var Directory and check that the path to the var directory is pointing correctly at your <KnowledgeTree Directory>/var folder

The above steps should resolve this issue on Windows and most Linux installs. For Linux users still encountering a problem, continue to Step 3.

3. Check that the following directory exists: <KnowledgeTree Directory>/var/proxies/nobody

If not, run the following commands from the terminal in order to create and set permissions for this directory:
mkdir <Path to KnowledgeTree directory>/var/proxies/nobody
chown nobody <Path to KnowledgeTree directory>/var/proxies/nobody
