Brian,

You also may want to have a look at this. It will mean you can see more debug information and may save a PSS call.

Thanks Vince - very useful! I'll try it out on a couple of scenarios where I can make the error appear.

Best regards,

Brian.

Brian,

I am using Virtual PC 2004 to connect to a development image with hosts Project Server 2007. I have connected the network adapter from the physical server on which it is hosted with the virtual adapter in the image. Then, I have assigned a unique static IP to the image so that it I accessible from our network. However, once we did this, the PWA (Project Web Access" has stopped functioning. Whenever we try to open it, it gives the error "An unexpected error has occured". Even when I open IIS and try to open the site (Project Server site), it tells me that the page is not found.

What could be the reason and how can I resolve this?

Hi Sharat,

I can only give you some general thoughts here - then you may need to go to http://support.microsoft.com or the newsgroups. You don't say how you are connecting, but I have seen similar issues to this when trying to use IP addresses where DNS is not configured correctly. WSS knows its own server names and will redirect to the name - even if you initially connect via a direct IP address. Either configuration of Alternate Access Mappings or a local hosts file will help if this is the cause of your issue.

Best regards,

Brian.

I tried all the above suggestions, but couldnot overcome the error. I am getting this error when I try to open mytasks page. I am the only member facing this problem in the company. All others face this error when they submit task updates using "Submit selected" button.

Do we need to apply any patch? any clue to solve the problem would be highly appreciated.

Thanks & Regards,

Sunanda

Brian,

I am having the unexpected error on the MyTasks page with one particular user (!) in a fully operational system, so I cannot (not being a programmer) fiddle about in a web.config file (which one in particular ?) too much with the risc of screwing things up for the rest of the 350 users. On the other hand I have a complete copy of this system in my virtual. Can you point me to the right web.config file in this case ?

Thanks in advance !

Glad you are thinking about your users Maarten. The web.config should be the one for port 80 by default - so would normally be found in c:\inetpub\wwwroot\wss\virtualdirectories\80.

Best regards,

Brian.

Another addition to the discussion is this: I spoke to my colleague and he mentioned that after a resource is assigned to a task in a projectplan and reported hours on the task the projectmanager assigns a second resource to the task. The first assigned resource gets the same error message. Once the second assignment is deleted from the plan the troubled resource gets to see his MyTasks-page again. This is clearly a bug. If ss, do you know this will be solved soon by the project-group ?

The latest hotfix (KB950816) contains a fix (QFE20994)that has eliminated this and other symptoms on the MyTasks page. I have tested for a customer and it works well.

Thanks Kermit - most if not all scenarios giving this error should now be addressed. You may need to re-publish to completely fix the problem after applying a hotfix.

I have a problem with Sharepoint 2007 and Project server 2007, i get an error message when i try to view my tasks. i have about 3500 tasks assigned to me but cant access the page.

Please help.

re: An Unexpected Error Has Occurred, or Unknown Error in WSS 3.0

BriSmith — Tue, 12 Aug 2008 19:33:58 GMT

Hi Syntax,

With 3500 tasks it could be time-out issues, or data issues with one or more tasks. The full error message may help identify which. We have addressed many of the data issues with hotfixes and the infrastructure update - what release level are you running?

Not sure what the error means in your case, but turning custom errors off and showing the stack trace for that web app may give a better error to troubleshoot.

I do have such error type with PS 2007 SP2.

When some of PS users try to open any timesheet

http://uasrv21/pwa/Timesheet.aspx?tsUID=9c12218c-3a0a-4a9b-9ee1-9189993271b7&Source=http://uasrv21/pwa/_layouts/pwa/timesheet/mytssummary.aspx

they get this error. When i enabled callstack the error description is as follows:

Just in case this may help anyone, I was able to resolve the Specified cast is not valid problem w/ the help of Microsoft. I had a few assignments that had null values for the assn_start_date and assn_finish_date in the msp_assignments table. I used this query to find the problem assignments (I added the task date fields just to see if there was a difference between them and the assn_date fields):

select a.assn_uid, a.proj_uid, a.task_uid, r.res_name, p.proj_name, t.task_name, a.assn_start_date, a.assn_finish_date, t.task_start_date, t.task_finish_date

from dbo.msp_projects as p inner join dbo.msp_assignments as a

on p.proj_uid = a.proj_uid inner join dbo.msp_tasks as t

on a.task_uid = t.task_uid inner join dbo.msp_resources as r

on r.res_uid = a.res_uid

where assn_start_date is null

The project plan showed start/finish dates for the task. I re-published the plan and the assignments updated w/ the correct dates. Once those were gone, I was able to open up the problem timesheets.

I received this error and it was down to a project being recorded with an invalid calendar UID (I have not bothered investigating why this happened as we are only testing).

To fix it I simply updated the CAL_UID column in MSP_PROJECTS to the base calendar UID and all is working fine again (select CAL_UID from dbo.MSP_CALENDARS where CAL_IS_BASE_CAL = 1)
