My site doesn't show in the site listing sidebar

Question

According to iWeb help, "Your websites are stored in one file called “Domain” on your computer. You can copy this file to another computer as a backup or to work on your site from another location."
When I open the file I've always opened to work on my site, called Domain.sites2, I am brought to the "choose a template for your webpage" window in iWeb.
In the site listing in the sidebar, where I used to see my site listed, I see only one item, "Site," with a downward pointing arrow next to it. If I choose a template for my page just so I can get out of the dialog, I see "Welcome" Listed under "Site" in the site listing pane, but still not my site. Of course the main layout pane doesn't show my site either.
When I close out without saving and preview the Domain.sites2 file with QuickLook, it shows a thumbnail of the site I am trying to access. The filesize is 6.4 MB. I tried using Time Machine to restore a version of Domain.sites2 from last year, but when opened, that also doesn't show my site in the site listing sidebar.
How do I access my site?

In Lion and Mt Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
To open your domain file in Lion or to switch between multiple domain files Cyclosaurus has provided us with the following script that you can make into an Applescript application with Script Editor. Open Script Editor, copy and paste the script below into Script Editor's window and save as an application.
do shell script "/usr/bin/defaults write com.apple.iWeb iWebDefaultsDocumentPath -boolean no"delay 1
tell application "iWeb" to activate
You can download an already compiled version with this link: iWeb Switch Domain.
Just launch the application, find and select the domain file you want to open and it will open with iWeb. It modifies the iWeb preference file each time it's launched so one can switch between domain files.
WARNING: iWeb Switch Domain will overwrite an existing Domain.sites2 file if you select to create a new domain in the same folder.  So rename your domain files once they've been created to something other than the default name.
