My PostgreSQL query contains an Integer parameter. In the Standalone Designer, it executes successfully both in design and in preview.

In the Web Designer, the same report is also previewed successfully. When I try to configure the SqlDataSource though, if I run the Execute Query in the final step, the database returns an error stating '...operator does not exist: integer = text...'

If the parameter is String, the query runs fine in design time of the Web Designer as well.
