Improve Form validation for subclasses to implement business and cross-field validation
---------------------------------------------------------------------------------------

                 Key: CLK-572
                 URL: https://issues.apache.org/jira/browse/CLK-572
             Project: Click
          Issue Type: Improvement
          Components: core
    Affects Versions: 2.1.0 RC1
            Reporter: Bob Schellink
            Assignee: Bob Schellink
             Fix For: 2.1.0


Its currently not possible for Form subclasses to override and implement custom business and cross-field validation logic in the #validate method, because the validate method is invoked *before* the Field values are processed and bound to request values.

Proposed solution is to rename the current Form.validate() method to Form.validateFileUpload (because that is what is currently does) and introduce a new empty validate method which subclasses can override. This is consistent with the approach taken by Field which also provide an empty validate method which subclasses can implement.
