An error in MvcMusicStore-v3.0_2

Oct 22, 2011 at 12:38 AM

I downloaded the “MVC Music Store v3.0b” from the source section. After run it with link http://localhost:26641/StoreManager and I found:

Create New à OK

Details à OK

Delete à OK

Edit à Not OK: When click Edit, edit form is opened. After modifying the contents of textbox, click Save à An error:

“Store update, insert, or delete statement affected an unexpected number of rows (0). Entities may have been modified or deleted since entities were loaded. Refresh ObjectStateManager entries.”

Why that?

How can I fix it?
