Christophe, I think Paul's point is that there shouldn't be any overriding happening : in his first case, these are private methods; hence, the @Override annotation would be incorrect. Sounds like a bug to me. Regards, Alex K On Wed, Sep 1, 2010 at 2:27 AM, Christophe Cordenier < chris

Hi ! Actually as far as i remember when method have the same name, the generated code would simply call 'init' method without method selection in this case. Anyway, Paul should use a protected or package visibility in his case and call super.init() on the parent class. 2010/9/1 Alex Kotchnev >

Christophe, I guess a part of the problem is that if I subclass from a parent class, I might not know what private methods it has. Thus, if the superclass ends up having a private method annotated w/ @SetupRender, and I accidentally end up having a private method in my class w/ the same name an

The "redisplay correctly" part should be handled by the default output encoding in T5 - thus, if the XML that is submitted in a form field and it's bound to a String property in your page or model, if you display/redisplay the form, it should render properly. I don't think you need anything specia

ParallelExecutor is a "service that allows work to occur in parallel using a thread pool". I doubt it's usefulness in your case. Simply create a new service, spawn threads in it as needed to do work and implement a few get status operations that your page(s) can call. That way, keeping the page up-

You can use ParallelExecutor service just fine, and to use injection do not instantiate a task yourself but make it a service with scope perthread. Davor Hrg On Wed, Sep 1, 2010 at 10:03 PM, Kalle Korhonen wrote: > ParallelExecutor is a "service that allows work to occur in parallel > using a th

Thread safety is your responsibility, but services are singleton by default and it shouldn't matter to your DAOs which threads they are accessed from. What you need to worry about is the consistency of your data. When you say "the new thread is created to process the data", what do you mean by it?

The new thread is the one that will run in the background. My concern, and it may not be a concern, is that the request processing will have created my DAO objects associated with a Hibernate session in that thread, and I'll access it from another thread (the one running in the background.)

Services in Tapestry IoC are always proxies(*); the proxies encapsulate thread-safe instantiation of the service, as well as the lifecycle of the service (singleton or perthread). Please see the documentation of the PerthreadManager service for some additional notes. So, yes, it is valid for a se
