Validation between two UIComponents
-----------------------------------

                 Key: RF-8498
                 URL: https://jira.jboss.org/jira/browse/RF-8498
             Project: RichFaces
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: component
    Affects Versions: 3.3.2.SR1
            Reporter: Alix Warnke
            Priority: Minor


What I would like to do is to be able to validate a rich:calendar in respect to another.
E.g. to immediately invalidate when a date has been set on one calendar which is not compatible with the date that has been set on another calendar.


Our current solution, to add the same validator in both calendars, does not work since the submitted values have not yet been updated on the backing bean.

In MyFaces there is something called "validateCompareTo":
http://myfaces.apache.org/sandbox/validateCompareTo.html 
Such a solution would do the trick here.
