'Unable to display this Web Part' Error

I was shown a 'Unable to display this Web Part' error when trying to view a BDC list, this was the steps I took to get rid of that error.


Below the error was the ID 27c287c1-c37d-42d8-8c98-f28d87aa587e

I looked into the SharePoint logs found in C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\LOGS and check the corresponding ID

This was shown,

I had the entity name wrong, after changing from bcd to bdc in the Entity Model, I was no longer seeing the error.
