hi tom, in this special case the usage of @SkipValidation wouldn't lead to a nice solution.
in case of bv + extval: there is a new add-on [1] for bv based multi-field-validation. however, also with this new prototype you would need group-validation (for this special case) to bypass the constraints hosted at the targets of the value-bindings. regards, gerhard [1] http://os890.blogspot.com/2010/06/multi-field-form-validation-with-jsr.html http://www.irian.at Your JSF powerhouse - JSF Consulting, Development and Courses in English and German Professional Support for Apache MyFaces 2010/7/1 <mynewsgro...@arcor.de> > Hi at all, > > I have the following use case simplified with an object 'Address' including > zip, city and so on using BeanValidation: > > public class Address { > > @NotNull(Create.class) > @Size(min=3, max=10) > private String zip; > > @NotNull > @Size(min=3, max=50) > private String city; > > ... > } > > This class should be used in two pages: for creating an address (both > attributes need to be set, group=Create) and to find an address (city is > sufficient for searching, group=default). > > In addition I want to reuse the address definition in pages to submit or > search an order with both a home address and an optional invoice address. > The problem is: if no value is entered into the fields for the invoice > address, it should not be validated at all.
