After update from 3.0.6 to 3.1.3, getting unexplained "Invalid column type"
I have an app that was working fine with 3.0.6. I'm upgrading to 3.1.3. I noticed that SimpleJdbcDaoSupport is now deprecated. I use named parameters, so I changed it to NamedParameterJdbcDaoSupport. Now my queries are all failing with "Invalid column type". That's all it's giving me. I can get the SQL it's using. I've stared at the parameter map I'm producing. I don't see what might be wrong, and the error message isn't helping me. I tried stepping into the "query" code (like "org.springframework.jdbc.core.JdbcTemplate.execut e(PreparedStatementCreator, PreparedStatementCallback<T>)", but it's still not giving me any useful information.
What can I do to narrow this down?
