Re: Using Hibernate in DAOs

Thank you very much for your answers. So, if I understood you well, I can let Tapestry inject the Session in my DAOs this way: class MyDAO { private final Session session; public MyDAO (Session session) { this.session = session; } public void performSomeOperationOnSession() { .

Re: Using Hibernate in DAOs

About creating threads explicitly... do we need to use PerthreadManager? I saw you recommend it here: http://tapestry.1045711.n5.nabble.com/Reusing-tapestry-hibernate-session-in-a-thread-td5438833.html On Tue, Feb 28, 2012 at 10:30 AM, Ferran Maylinch wrote: > Thank you very much for your answer

classloader issues casting objects to their tapestry type

Hi Tapestry committers/experts (in particular) I while back I posted that I had found a classloader issue within one of my services when casting a Zone to a Zone. I realise that what I'm trying to do isn't quite the 'tapestry recommended approach', but since some of my pages update many zones

Re: Using Hibernate in DAOs

Ferran, You can just @Inject the session in if you want to write less code: class MyDAO { @Inject private Session session; public void performSomeOperationOnSession() { ... } } and then yes, you must use PerThreadManager explicitly if you are creating your own threads using the Dao.

Howard, I tried the ptm.run(...) idiom you posted and I found that the changes are not committed. How can I commit the changes I perform inside that thread? I suppose I can't add @CommitAfter to the method that starts the thread because that method will probably end before the thread. But I tried

Re: classloader issues casting objects to their tapestry type

Thanks Thiago, I wasn't fully aware of the 'controlled package' concept, however it does make sense. I tried casting to 'ClientBodyElement' and while the cast works, I found the zone update does not succeed since at that point the object has not been assigned a clientId. I find this strange si

You will have to call commit directly, or via HibernateSessionManager. Have a look at how CommitAfterWorker uses HibernateSessionManager. You need to do the same within your thread. On 28/02/2012 10:11 PM, fmaylinch wrote: Howard, I tried the ptm.run(...) idiom you posted and I found that th

Sorry, it was a newbie mistake... I simplified my test and found that even a simple call to a service (no extra threads involved) was not being persisted, and the cause was the lack of adviseTransactions() method in the module. @Match("MyService") public static void adviseTransact

How to get values in a form with dynamic fields?

Hi! Firstly, sorry for my English... I hope you understand me... I'm doing a project about form management (such as fill, delete...). When user wants to fill a form, has to select one from an available list of forms. Depending on selection, form will have different number of fields (fields are ta

Thanks Thiago, this is the method I ended up implementing. I wasn't sure if there was a better way of handling this.

Same service known by multiple interfaces?

I have an interesting case where I'm trying to fit third-party code to work under Tapestry IoC. A service is made available by binding to the "main" interface of a class, but I know the implementation supports another interface. Is there a way to make it known with the other interface as well for t

Re: Same service known by multiple interfaces?

I've thought about these "chimeric" services before. Let's say you want to seperate services, A and B. You have an implementation class IM that implements both A and B. Define a new interface, C: public interface C { A getA(); B getB(); } public class CImpl implements C { public final IM im

Thanks Howard. Yes, that's quite a bit of boilerplate but looks like the only other option, especially if you want both A and B separately known as services. Kalle On Tue, Feb 28, 2012 at 12:03 PM, Howard Lewis Ship wrote: > I've thought about these "chimeric" services before. > > Let's say you

Hi! Caching seems complex and I am fairly new to it. I found out that T5 delivers a 304 for assets that have not been modified since they where fetched. I.e. there is one server request per asset. [When serving an asset T5 delivers a last modified header. And clients sends If-Modified-Since when
