Hi,
Ok i provide you an example. Our objective is to build small component like
personal data, address etc... This small components are included in a Page.
Page will controller the validation for all components and general events.
For example:Page Tml
>
>
>
> ....
>
Page POJO
public class NewPage
{
@Component(id="newForm")
private Form newContractParticularPage;
@Property
@Persist
private PersonalDataVo _personalDataVo;
...
}
The first problem that you can faced it that the variable _personalDataVo
has to be initializes the first time. Ok, you can do it is initializes the
Value Objects in the pageLoaded Method, but it is not enoug because if you
have a singleton page the data blood for all request once one user fill up
this value Object. How to avoid, let see the components part. If you realize
we have machting tesfield with t:value="personalDataVo.nombre". if you see
the code for Java component at the end we make responsible for
initialization of Value Object to the component throught to the
setupInializes.
personalDataCmp TML

>
personalDataCmp POJO
public class PersonalDataCmp
{
@Property
@Parameter(required= true)
private PersonalDataVo personalDataVo;
@SetupRender
void initializeValue()
{
if (personalDataVo==null)
personalDataVo=new PersonalDataVo();
}
...
}
This works an data don´t blood in requester but at the you have to controll
in your code. We follow this pattern because our application is complex and
we have to make component, following 3 layers (with EJB (business logic) +
hibernate ) and not two like is orientated tapestry. For this reason we need
indenpendance ValueObject (POJO) as databag to call EJB part and to reduce
the complex in tapestry POJO.
In this structure at the end we have problems in the comunication between
components and Pages events + validations as well as data blood as we
disccuss in this thread. I am not an expert in tapestry but I think that
data blood problems will have been controlled by the framework like it was
controlled in the version 5.01 or to clarify that the tapestry 5.2 has
changed become from a POJO to a tipically in a Servlet.
In other hand thanks for your help and quick reply.
Get in touch...
Kind Regards
