Re: BeanEditForm and Polymorphism
Of course. I started with tapestry some months ago so im not an expert but i will share everything im learning with others through tutorials (hopefully i will end some by the end of this week). The hardest part of tapestry is starting with it. If we all share our knoledge with newbies, it will be much easier and more people will start using this great framework. -- View this message in context: http://tapestry.1045711.n5.nabble.com/BeanEditForm-and-Polymorphism-tp3343510p3344123.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: BeanEditForm and Polymorphism
Thanks Werner. The problem here was that i wanted a generic method. At first, i dont know what kind of subclasses are avaliable because they are managed by a service so i can add more subclasses just annotating them and i will have more subproducts avaliable without any code changes. Because of this, i needed to work with the superclass type. Im going to explain it a bit more because may be usefull for anybody else. Think on a extensible shop. I have my base products with the basic fields (Id, Name..). At any time, i need some new kinds of products with different fields so i create some subclasses of my base class Product. The problem, as i said, is that at first, i dont know what kind of products i have avaliable since its dinamic depending on the classes i added and may change at any time depending on my needs and i want it to be extensible without having to hardcode the changes for the new subproduct. I want it to be added as a Product subclass, annotate it and get it working without more changes. Because of this, i annotate these Product subclasses and through annotations and reflections they are registered into a custom service. Now i want a page where i can select some kind of product through a select box and get a beanEditForm where i can create a new "subproduct". The problem is that the beanEditForm has to accept a generic type (the superclass) and adapt the fields to the kind of product selected. I solved it setting the beanEditForm model through a method, and this metod creates the BeanModel based on the selected suproduct. I will make a tutorial about this asap. Hope you understand.

BeanEditForm and Polymorphism
Hi all.
Im developing a new project and im having some problems with BeanEditForm
and inheritance, maybe you can help me.
I have a base class called product.
>From that base class (abstract class or interface, doesnt matter) i have
different subproducts extending from this base class.
I want to create a page where i can create different types of products so i
have a dropdown menu, where i select the type of subproduct and i want to
create, deppending on the type of product selected.
My .tml will show something like this
My .java will be something like this
private SubProduct subProduct;
public Product getMyProduct(){
return subProduct;
}
so the BeanEditForm will show the Product superclass fields but subProduct
specific fields wont be shown.
The problem is that the beanEditForm takes the parameters from the
supreclass/interface so i only have the supreclass attributes fields. Any
idea about how to do this?
Thx in advance

Re: Discussion- the verdict
I started with tapestry 5.1.2 some months ago thanks to a book called "Tapestry 5" from "Alexander Kolesnikov". It was a bit hard to understand how to create sites with this framework and yes, i also noticed the lack of documentation but with each new release it went better. Each time i had a problem i just came to this board and it was solved very fast, the documentation has increased by a lot on the last months and its going better and better very fast. A "Tapestry in Action" book is on the way too and i think this framework is great. I near left tapestry because of that kind of comments on some forums but finally i decided not to and im very happy with my decision. Im starting to understand a lot of new things and the way Tapestry+Hibernate work is just great. Its very easy to create new modules and componentes even if they need new Hibernate Entities, add this component to your maven dependencies and its working and the new entities created and managed by Hibernate without aditional configuration making extensibility easier and fast. I think tapestry, with a bit more documentation will be a great framework and will make things easier and faster. Its hard to start? Yes... and i will try to help with simple tutorials from my own experiences since i was a totally newbie some months ago, but i think think in a short time, we will get our reward. We just need to show the people how easy it is and the potential it has. -- View this message in context: http://tapestry.1045711.n5.nabble.com/Re-Discussion-the-verdict-tp3337928p3339859.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Re: Tapestry custom component + hibernate
Having problems again. My packaged component is working fine except the
hibernate part.
I have my main app and a custom componet packaged into a jar. This component
has:
com.udc.mylib.entities
com.udc.mylib.pages
com.udc.mylib.services
...
When i load the packaged component, its displayed correctly into my main
application but when it comes into action and hibernate part should work, it
fails giving me an exception:
Unknown entity: com.udc.mylib.entities.Hello
(Obviously my entity is called "Hello" and its into com.udc.mylib.entities
package)
When i try to add the package with
public static void
contributeHibernateEntityPackageManager(Configuration configuration)
{
configuration.add("com.udc.mylib.entities");
}
i get an error saying:
Use of the same entity name twice: Hello
so i suppose it was correctly loaded but somehow, it cant be found.
Any advice?
Thx in advance

Tapestry custom component + hibernate
Is it possible to create a component that uses some hibernate entities, package it into a separated .jar and then import this component into my main project being able to autocreate this new entities? Something like creating my custom component package following this tutorial http://tapestry.apache.org/tapestry5.1/cookbook/lib.html Inside that component, create the "entities" package like at any other tapestry+hibernate project with my custom entities. Will tapestry load those entities after adding this packaged component into my project? so if i have the autocreate entities activated on the hibernate.cfg.xml, those new entities will be added. What im trying to do is an extensible application, where anyone can create their own custom components, with the needed entities if this components need to store their own data into the database, and being able to do this without having to modify my main application. I just download the component made by "someone", add it to my main project and i dont have to add the mapping myself to my app because its included into that component. Hope you understand what im trying to do. Would it be possible? I would test myself but im still having troubles with components packaging... -- View this message in context: http://tapestry.1045711.n5.nabble.com/Tapestry-custom-component-hibernate-tp3254963p3254963.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Re: How to set up Tapestry 5 on Tomcat 5
Well... if i understand u correctly u download tapestry from the website (so u are not using maven). The needed libraries depends on what are u goning to do. For a simple project you will need tapestry-core and tapestry-ioc, those are the main ones. Anyway, i would recommend u to use maven because you need an specific files structure and its much easier with maven, since its created automatically with it.

Problem with components TML files
I created a simple project with Maven archetype (the 4.2.0 version from the tapestry.apache.org catalog) . I open it on Netbans 6.9.1 as a maven project, everything is ok, i create a custom component at the "components" package adding the java and the .tml file.

After looking into the compiled version, i see that the component TML page is missing... just the component .class appears.

Capturing hibernate exception
I have a project where im using hibernate with Tapestry. Everything works fine. Following the tutorials, i created my Hibernate entities, i created my DAOs where i inject the hibernate session at and i use them for my data access. The problem comes when my database fails (its down, unreachable or whatever). I get a weird tapestry error page cause of the components trying to access to data. Is it possible to configure tapestry (or tomcat, dunno who should manage the exception at this point) so i can capture if database connection with hibernate fails and im redirected to a custom error page?

Update zones after session object changes
Hi. Im new to tapestry and im trying to do some projects but its a bit hard because of the lack of documentation. Well im doing a simple shopping cart. The cart is stored into my session and im developing some components for showing the data. I made this with the ajaxformloop component so im able to delete a product from the shopping cart with an ajax request. Everything works fine but i want other zones to be notified someway so they reload their content (they show the cart content too) updated after changes. So: I have a component developed by myself that recieves the shopping cart stored into my session as parameter. This shows a list of my shopping cart products with delete buttons for each one and works fine but i have more components into my page showing this cart contents and i want them to be updated (or notified that something has changed) once i delete one product from the cart. I could reload the page too but didnt want to (that way using ajaxformloop would be stupid... i would use page redirections). Is it possible?
