Here’s a simple one, but it underscores how important good error messages are.
You are in SharePoint 2010 on a task list and you are attempting to update the task status and other columns using the datasheet view. You get an error:
“An unexpected error has occurred. Changes to your data cannot be saved. For this error, you can retry or discard your changes.”
You are presented with the following dialog.
Not very helpful, huh?
No matter how many times you retry your changes, you get the same general error.
So you try to update the item using a standard SharePoint form and you receive an error with a little more meat.
“This item cannot be updated because it is locked as read-only.”
Now you are suddenly reminded that in-place records management is enabled!
You check the Compliance Details for the item and find that you declared it as a record before Christmas and that has put a read-only lock on the item.
You also find your memory is mush from the holidays. There is no solution for that.
