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.
