I have a simple sandbox solution with a webpart (which loads data via Linq but thats not the point I think) and everything works fine on my development machine.

When I install this solution on another machine and add the webpart to a page I get the following exception. But I don't know why and what to do and I think its not related to my solution as I can't see any reference to my application in the stack trace.

Any idea?

Web Part Error: Unhandled exception was thrown by the sandboxed code wrapper's Execute method in the partial trust app domain: An unexpected error has occurred.

[SPUserCodeSolutionExecutionFailedException: Unhandled exception was thrown by the sandboxed code wrapper's Execute method in the partial trust app domain: An unexpected error has occurred.]

  • Can you post part of code? I think if sandbox solutions weren't enabled, you would get error informing you about this. And can you test something following: commenting out all the code that refers to SharePoint context, publish your solution, add webpart (which will most probably show nothing) and after that - uncomment your code and redeploy solution - I had some weird Null-pointer exception on SPContext.Current, when i was adding sandbox webpart to page, but when it was already on page - everything worked fine. – Marek Kembrowski Dec 03 '12 at 12:10
  • I think the actual code wouldn't help, its to complicated to show. But I have a try/catch around everything in the webpart which is not triggered? But I will try your suggestion! – Marc Jan 17 '13 at 08:30
  • I've just seen exactly the same error - did you have any luck with this? – Dylan Nicholson Mar 12 '14 at 06:35
  • I'm not quite sure as this is too long ago but make sure you release all objects related to SPSite, SPWeb etc (use "using") as this can cause this problem if I remember it right. – Marc Mar 12 '14 at 10:16

Check if sandboxed solutions are enabled (correspoding service is running on your server). Also check if you are actually installing this solution as a sandboxed, not as a regular or vice versa.

  • Sandbox solutions are enabled, I have another webpart which works fine. And yes, it is installed as a sandboxed solution. – Marc Jan 17 '13 at 08:28
