hi, as mentioned in my previous post, i added the functionality to the validation strategy for @RequiredIf [1] the changes are compatible with existing versions of extval. i'll provide details about using it with already released versions, if someone would like to use this improvement with a released version instead of the next milestone.
furthermore, i added some information to the wiki [2] (the section "conditional validation via cross-validation") regards, gerhard [1] http://issues.apache.org/jira/browse/EXTVAL-72 [2] http://wiki.apache.org/myfaces/Extensions/Validator/Getting_Started/Cross_Validation http://www.irian.at Your JSF powerhouse - JSF Consulting, Development and Courses in English and German Professional Support for Apache MyFaces 2009/11/19 Gerhard Petracek <[email protected]> > hi, > > since it's a nice idea to have an out-of-the-box support via @RequiredIf, > i'm going to add such a feature to the validation strategy for @RequiredIf. > it will be available in the next milestone (which will be published quite > soon). > > regards, > gerhard > > http://www.irian.at > > Your JSF powerhouse - > JSF Consulting, Development and > Courses in English and German > > Professional Support for Apache MyFaces > > > 2009/11/18 Gerhard Petracek <[email protected]> > > hi, >> >> basically the current implementation of @RequiredIf is designed to be used >> in combination with two text-input fields. anyway, it's quite easy to solve >> the requirement with the cross-validation mechanism of myfaces extval. you >> can also implement a @ValidateMyCustomConstraintIf based on the >> infrastructure of extval. i'll create a wiki which describes the required >> steps. >> >> additional information: >> if the information is already available in a bean, you can use >> @SkipValidation as well.
