Acknowledged. This is the typing issue that I mentioned earlier. The datatype that has default form uses is no longer working as before, and data is not retrieved successfully. I guess what we see is simply the result of retrieving an empty string as data, and trying to use it as a title text with namespace Form:.

A similar problem did occur with "has type" and a new way of storing it is introduced in SMW 1.6. Basically, this is due to an internal incompatibility between the special property table in SMQSQLStore2 (this stores plain string values), and the data item that all wiki page properties now use (which needs to store all the fields of a wiki page). I will think about a solution for the SF types as well.

The problem should be fixed in the current SVN. Ideally, all existing data should immediately become accessible after update, even on pages that have been modified since the problem occurred.

Yay, it works!! I believe this was the last major step before SF 2.2 can be released.

We tested it for 1.17beta, and it works their is well.
