Java 5 Tapestry 4.0.x I would like to make runtime checks to determine if a link will render. To avoid configuration tedium we do not want to use custom link renderers.
The desired solution would behave like around advice, it would: - intercept the render() call (or some other method with HTML generation responsibilities) - make a runtime check based on the user authorizations and the target (e.g. page, component etc) - call/skip the superclasses/targets default render() implementation Based on a variety of other posts, it seems like the EnhancementWorker and EnhancementOperation are best suited for this. EnhancementOperation.addMethod() would allow me to extend the base component class and add any arbitrary code. However, if any other worker has modified the method, the EnhancementOperation will throw an exception. I assume the same would happen if a worker attempted to use extendMethodImplementation on the render() method. This might be a moot point, because I we don't use any EnhancementWorker's that conflict with our impl. However, all things being equal, I would like a guarantee that our enhancement won't cause a runtime conflict. Is there a better way to provide these enhancements, perhaps using Hivemind's proxy support? Thanks for any help!
