Hi.
In this code article ( http://msdn.microsoft.com/en-us/library/jj573263(v=office.14).aspx ) which creates a visual web part that allows tabbed display of other web parts there is a bug.
When the tabbed web part is deployed if the user clicks on a list item that is displayed within the tabbed web part an error is displayed as follows:
I can see from the View Source of the page where the web part is added that there is a WebPartID="" on the page but I don't see where this is created within the MSDN code. Bugs are a regular occurrence in MSDN article sample code but this one seems particularly difficult to track down. It's not even possible to post a comment on the article page asking for help on the code so that is why I am posting here.
There are numerous other posts on these forums relating to this error message but none fix the issue.
Why does this error occur and is there a fix?
