List View Error: "Attempted to use an object that has ceased to exist."

I was copying a SharePoint list from 2007 to 2010, and all appeared well until I clicked on the List View, which gave me the following error:

Attempted to use an object that has ceased to exist. (Exception from HRESULT: 0x80030102 (STG_E_REVERTED))

I could see the items just fine using Site Manager, but everytime I looked at a view I would get the above error.

From looking in the logs it pointed me to check my List View Threshold, which I had happened to exceed.  So going to Central Admin and raising the threshold for my web application did the trick.

Downloading InfoPath Form .XSN from SharePoint

I'm posting this when you need to download the latest InfoPath form for editing directly from SharePoint and can never remember where to find it.  Not saying that it happens to me often, but it might.

• Go to the list where the InfoPath form is published.
• Click on the Library tab in the ribbon, and click on Library Settings
• Go to Advanced Settings
• In the Document Template section, underneath the Template URL, click on the Edit Template link.

Then you can save it, make your edits, and publish it back up there.

Rich Text Editor Stripping Absolute Urls

If you're using a Multiple lines of text column and select Rich Text, SharePoint turns any absolute urls that point to the server into relative urls.  I've had cases where I'm referring to that text from other web applications, and I've found the easiest workaround is to just use a TinyUrl...

SharePoint "Validation of viewstate MAC failed"

I had a button on a SharePoint page and was posting back to the page with the ID of the item I was using, so my page was:  /Pages/Order.aspx?ID=5 and I kept getting the following error:

"Validation of viewstate MAC failed"

After toying around a bit I realized that the ID parameter is a reserved querystring parameter and can't be used, so just changing the name of the parameter fixed the issue.
