Doing auto-reloading right is very tricky. You have to have control over the lifecycle of objects, and the class loaders for those objects. For Tapestry components this is possible and is, in effect, a side-effect of the transforming technology that allows components to operate. To allow the same kind of reloading beyond components is more involved, and would turn Tapestry into an application server, rather than a framework. Simply reloading a class may not be enough. For example, what if the class being reloaded is a module class, thus changing the configuration of the IoC container (including the configuration passed to some services)?
Changing even a service implementation can have a rippling effect: the new implementation may have new dependencies. Values obtained from the old service may have been passed to other services; with external XML configuration it might be possible to track this, but with Tapestry's Java-centric approach, it is virtually impossible to know what data has moved about the system.
