Hibernate Session problem
Hi all. I'm having this trouble with hibernate.
I really dont know why, but i think it is in relation
with continuations or forms.
It works some times but other not, so I'm confused.
I get this exception:
org.apache.cocoon.ProcessingException: Error calling

It happens in this flowscript function defined in
"flow/beans.js":
function beanForm_form() {
openHibernateSession();
var form = new
Form("forms/beanForm.form.xml");
form.createBinding("forms/beanForm.bind.xml");
// This is a nice feature :-)
var bean; // The java bean to work with
var id = cocoon.request.getParameter("id");
var updating = id != null; // We can be
updating or adding beans
if(updating){
bean=hs.find("from Bean where id = " +
id).get(0); // Retrieve from the database
} else {
bean = new Bean(); // New bean
}
form.load(bean); // Bind the bean to the form
form.showForm("beanForm.form.template"); //
Shows the form. Another nice feature ;)
form.save(bean);//Once the form is validated
it is binded to bean
if(updating){
[24] hs.update(perfil); // Update the bean
} else {
[26] hs.save(perfil); // Store a new bean on
the database
}
cocoon.redirectTo("bean.list", true); //
Redirect to a page wich shows a list of beans
}
And the 111 line in sitemap.xmap is a basic
continuation.
<map:match pattern="*.continue">
[111] <map:call continuation="{1}"/>
</map:match>
This is a function which work on both modes "New" and
"Edit" beans, so it fails on lines [24] or [26]
depending what you are doing.
I tried to put another "openHibernateSession()" before
de "if(updating)" but it again work sometimes and
others not.
Do continuations have some strange behaviour against
HibernateFilter, or may be the redirect ?
When I get the error page (with "bean.list" as url), I
press the "go to" button of firefox and I get the bean
list with the new or the modified bean, so I think it
must be working.
I'm really confused, so I'd be glad if some one could
give me a help.
Thx for your reading.

[RESOLVED ? ]: Hibernate Session problem
Posted by Manuel Mata <ma...@yahoo.es>.
Hi again. I think the problem was on continuations,
but not a problem at all.
I had to open a new Hibernate session after the
form.show(...) because if the form is not validated it
is shown again, but the hibernate session was closed
by the HibernateFilter. Then when the form was
validated i tried to update or save a bean and throws
the exception with the hibernate session closed.
Another thing was the flush after the update or save.
Dont know why but adding a hs.flush() after the update
or save it works fine. If i dont add the flush i get
the exception again. Why ?
See ya.
