My Tasks generates NullReferenceException but My Work link is fine

T

thinkmassive

Our PM noticed a peculiar error in PWA. For some accounts, the My
Tasks page generates an ASP.NET exception. This only happens for some
users, and it doesn't happen when *anyone* clicks the My Work link,
which also displays My Tasks. The only similar problem I have seen
involves not having spaces in custom field values, which we don't even
use.

I've included the entire error message below. If anyone can provide
any insight I will be grateful.

Thanks in advance!

I apologize for immediately responding to my own post, but two
important things I should add:
1. Microsoft Project Server 2007
2. I have rebooted the server and nothing changed.

OK, MyWork and Tasks are diferent .aspx pages but use the same Webpart, if
the webpart work fine in one page its because the tasks.aspx page have a
problem, maybe the user tried to modify the properties of the webpart or
something.
You have to restore the configuration of the tasks.asp page:

Log as administrator, go to mytasks, edit the page, remove the webpart and
add it again.

See Sharepoint help for the action.

BTW, the InitializePager bug happens when the grid attempts to load a
page index that does not exist. This bug was fixed in SP1.
