Spring Projects Issues

**[Oliver Drotbohm](https://jira.spring.io/secure/ViewProfile.jspa?name=olivergierke)** commented Thanks for reporting this. Just to make sure: > When constructing a Querydsl predicate from request parameters, the source type is inspected to determine which parameter names...

**[James Howe](https://jira.spring.io/secure/ViewProfile.jspa?name=jamesmhowe)** commented > You mean the opposite, don't you?
