Rich, I have a question about the suggestion to create and use the FBAPF. It seems that this would work only in the case that the standalone includes the @ Jpf.FormBean annotation. However, users can define validation rules without @Jpf.FormBean and just use @Jpf.ValidatableProperty. The FormBean allows the class to define its own message bundle for validation errors, but it's just an option.
We need to make sure that we check the ValidatableProperty before going to generate() to provide AP error information. The ValidatableProperty can be on a method (of a bean) and an annotation type (listed in the @ Jpf.Controller or @Jpf.Action). Since it's not just associated to a type, would we still be able to do something like you suggested and create an AP factory for ValidatableProperty? Maybe I'm missing something though with what you were suggesting. Thanks, Carlin On 8/14/06, Rich Feit <[EMAIL PROTECTED]> wrote:
Hey Carlin, I think what might be better would be to make a FormBeanAnnotationProcessorFactory in compiler-apt/org/apache/beehive/netui/compiler/apt, and make it responsible for the form bean annotation (you'd need to remove that annotation from the list of supported annotations in PageFlowAnnotationProcessorFactory). FBAPF could then simply return a FormBeanCoreAnnotationProcessorFactory -- which already exists -- in its getCoreProcessorFor(). I honestly cannot remember why I didn't do that -- sorry. If it turns out that this doesn't work for some reason, you could also roll the functionality from FormBeanCoreAnnotationProcessor into PageFlowCoreAnnotationProcessor (and to delete the former). In either case, you end up with standalone checking form bean classes, which is nicer because you don't have to worry about multiple PageFlowCheckers triggering checking on the same external form bean class, and it's just cleaner to have it be standalone. All that said, I didn't wire it up in the first place, so if you run into any difficulties let me know -- it's possible there's something I'm missing here.
