Newbie forum and jumping to another page
Hi,
I'm having some trouble shifting from the conventional event-driven model to
the way Tapestry works.
Is there a newbie forum where I can ask the most basic questions?
Right now I'm stuck trying to jump from one page in charge to create users
to others in charge of editing and deleting them.
This is the code of the list with the already created users is:
<t:grid source="usuarios" add="editar,borrar" rowsPerPage="5"
include="nombre,controlarUsuarios,crearProyectos">
<p:editarcell>
<t:actionlink t:id="editarUsuario"
page="seguridad/editarUsuario" context="nombre" >Editar</t:actionlink>
</p:editarcell>
<p:borrarcell>
<t:actionlink t:id="borrarUsuario"
page="seguridad/BorrarUsuario" context="nombre" >Borrar</t:actionlink>
</p:borrarcell>
<p:empty>
<p>No hay informacion en la lista.</p>
</p:empty>
</t:grid>
Both seguridad/BorrarUsuario and seguridad/editarUsuario are pages intended
to handle the delete and edit tasks (sorry the code is in spanish). However
the jump never happens and the methods onActionFromBorrarUsuario and
onActionFromEditarUsuario are being called on the page where the grid
exists.
Then I thought that returning a BorrarUsuario page from this methods should
be enough, for that I put:
@InjectPage("seguridad/BorrarUsuario")
private EditarUsuario eu;
or
@Inject
private EditarUsuario eu;
And then perform a simple
return eu;
At the end of the onActionFromEditarUsuario method, but I keep getting tons
of exceptions:
java.lang.ClassNotFoundException: caught an exception while obtaining a
class file for
compucentro.volumetria.pages.seguridad.ControlDeUsuarios
With:
Error obtaining injected value for field
compucentro.volumetria.pages.seguridad.ControlDeUsuarios.eu:
No service implements the interface
compucentro.volumetria.pages.seguridad.EditarUsuario.
What am I doing wrong? I think that I'm missing come naming convention or
something but cant find what.
It would be very nice to have a tutorial on how to implement a full
create/update/delete cycle using hibernate, that way a newbie can get the
feeling of how manage the set of objects (pages, entities, etc. ) involved
with DB access.
By the way, I had been exploring tapestry for only 2 days now, so please
forgive my lack of knowledge on the topic.
Thank you and best regards.
