The resource object with key 'NamexxxField' was not found

Normaly a solution deployment would copy important dll's, resource files etc. to the Global_Resources map in your (inetpub) web applications bin directory. Somehow one of my build SharePoint solutions didn't copied those file during deployment.

I recieved the following message

Exception Type: System.Web.HttpException Exception Message: The resource object with key 'NamexxxField' was not found.

I needed to execute the following command to fix the problem:

"C:\Program Files\Common Files\Microsoft Shared\web server
extensions\12\BIN\STSADM.exe" -o copyappbincontent

After that SharePoint had copied the files and my solution worked correctly, but my wsp needed futher investigation.

Remove lost/broken Webparts

Previously, I retracted a solution from my web application. The consequence of this action was that I was not able to load the pages anymore. I recieved:

Error

An error occurred during the processing of . Could not load file or assembly 'Solution.WebParts, Version=1.0.0.0, Culture=neutral, PublicKeyToken=a7985c93d0151889' or one of its dependencies. The system cannot find the file specified.

In this case, the only thing you have to do is to remove the webpart. Removing the webpart in the webpart gallery doesn't solve this.

Solution:
Append ?Contents=1 to the webpart page's URL to display the Webpart Maintenance Page. On that page you can delete the malefactor.

Example: http://moss/default.aspx?contents=1
