Search suggestions fail in 2.2

My application uses in-app search, dynamically builds search suggestions on each request, puts them in a MatrixCursor and returns the suggestions to be displayed. Info on search suggestions here:
http://developer.android.com/guide/topics/search/adding-custom-suggestions.html

This works perfectly fine in 2.1-update1, but when I loaded it on a 2.2 phone, I get a fatal error when I try to search. Here is the relevant logs:

where "My String Message" is the value of the SUGGEST_COLUMN_TEXT_1 field of the first (in this case only) row to be returned as a suggestion in the cursor. The stack trace does not touch my code at all, and following it in a debugger shows the error occurs some time after I return the suggestions cursor in my search suggestion content provider.

Why is their adapter suddenly trying to interpret a String as a Long? Has anyone else encountered this?

Thanks!

+1  A: 

The code is failing when it's trying to access the ID column ("_id") which is required in any search suggestions cursor, and must be a Long.

Is it possible that you're not including that column, or, you're creating that column but writing your strings into it inadvertently?

See http://developer.android.com/guide/topics/search/adding-custom-suggestions.html#SuggestionTable

This was the problem. When I got the code there was a string (same string as for text1) going into ID but it wasn't important and on 2.1 it worked so I just left it. Apparently on 2.2 it is fatally enforced as a Long.
