Re: Tapestry - hibernate problem
The session isn't closed until you are leaving the request, after your
template has rendered. The problem is most likely with your query or
your data. Try accessing the values from your component class and you
should see that it's still null.
You should also enable logging for hibernate to see exactly what it's
loading and what query it's running.
if you're using log4j.properties you can try these:
log4j.category.org.hibernate.type=trace
log4j.category.org.hibernate.cache=trace
log4j.category.org.hibernate.SQL=debug
and these to your hibernate properties.
hibernate.show_sql=true
hibernate.format_sql=true

Re: Tapestry - hibernate problem
My mapping are ok, because yesterday I used eager fetching on all collections
and it worked, I just removed every eager mappings and create criteria for
all one level criteria, problem is when I try to go deeper...
It seams that problem is that session is closed when I try to fetch data...
It seeams that tapestry is closing hibernate sessions automatically.
Someone told me to implement open session in view... Any suggestion about
that matter?
Tnx for your fast answers :)

Re: Tapestry - hibernate problem
Hi,
You should check your mapping to be sure the many-to-one relationship
between "comment" and "user" is correct, and verify your database table
"comment" contains an existing foreign key to the user table.
Best thing to do is to run your Criteria in a JUnit test.

Re: T5: tapestry-hibernate problem when setting @Persist("entity") to a transient object
You're not doing anything wrong, per se.
The exception is pretty clear: Only entities attached to a Hibernate
Session can be persisted.
If you go a step further, it turns out that only entities which have
been previously committed to the db (ie: have a valid db id) can be
persisted with @Persist("entity"). One possibility would be to file
an "improvement" jira, suggesting that @Persist("entity") falls back
to storing the entire object in the session if it is new (no dbid) or
transient (not connected to a hibernate session). Otherwise, go back
to using @Persist alone (which defaults to session), as it will work
perfectly well for transient as well as non-transient objects, at the
cost of increased memory use for the session.

T5 tapestry-hibernate: problem with type coercing of HibernateEntityValueEncoder
hi, the HibernateEntityValueEncoder creates ValueEncoder for every contributed Entity class that's nice... but if i submit a page with a select component that used a list of entities to generate the selection model i will receive an exception if no option was selected! this is because the ValueEncoder will try to coerce the empty field to the type of the id field!! (i use blankOption=ALWAYS) the problem now is, that if i contribute my own ValueEncoder i get an IOC warning that there is already one registered for my entity class. I need either a way to disable the HibernateEntiyValueEncoder or a way to override the automatically generated ValueEncoders with a custom one. i think the HibernateEntityValueEncoder should only then attempt to reload the entity if the value is non-empty; if empty or null it should return null any suggestions? JIRA? g, krsi
Re: T4.1.3 Tapestry-hibernate problem
Hi Grigoris
I will assume that your form is surrounding the @For component.
Advices:
* remove the updatePassenger it will confuse things.
* persist "passengerList" in the session
* populate "passengerList" on pageBeginRender
* add a "keyExpression" to the For component
* then save all the passengers at once.
public void savePassengers() throws DataAccessException {
try {
for (Passenger passenger : getPassengerList()) {
getSession().saveOrUpdate(passenger);
}
} catch (HibernateException e) {
e.printStackTrace(); //nkons debug
throw convertHibernateAccessException(e);
}
}
I hope it helps.
Regards.

T4.1.3 Tapestry-hibernate problem
Hi all,
I have a dynamic form where the user can set a dynamic number of passengers.
The html looks like:
Title
Name
Surname
Age
The updatePassenger is an InvokeListener that executes this code:
public void updatePassenger(IRequestCycle cycle) {
if (cycle.isRewinding()) {
setCurrentPassenger(getPassengerManager().getPassengerById(getCurrentPassengerId()));
getPassengerManager().savePassenger(getCurrentPassenger());
} else {
Passenger passenger =
getPassengerManager().getPassengerById(getCurrentPassengerId());
setCurrentPassenger(passenger);
}
}
(The idea is that in the beginning I retrieve every Passenger's data from
the database and when the form is rewinding I store them in the database
again)
The getPassengerManager() is a class responsible for handling the Passenger
objects, based on hibernate. The savePassenger function is:
public void savePassenger(Passenger passenger) throws DataAccessException {
try {
getSession().saveOrUpdate(passenger);
} catch (HibernateException e) {
e.printStackTrace(); //nkons debug
throw convertHibernateAccessException(e);
}
}
The problem is that when the user submits the form in which all these are
contained, the savePassenger is called (as it should) but nor does it update
the passengers or throw an exception. What am I doing wrong?
The thing is that in the list with passengers, I am keeping the Ids of the
passengers, not the full Passenger Object, because the DataSqueezer produced
long strings that (I believe) caused some random problems in submission:
blank screens or no reaction.
I am using Tapestry 4.1.3. Any help would be really appreciated. Thank you
in advance,
Grigoris

Re: tapestry hibernate problem
you shouldn't persist any object from hibernate
@ApplicationState
private Customer _customer;
same object will be referenced in you second request,
and the second request will have different session,
tapestry-hibernate integration is still basic,
and for now you should just change the above
code to persist Cutomer.id and fetch the customer
using the session in each request...

tapestry hibernate problem
Hi,
i have tried the tapestry-hibernate package to handle my hibernate
sessions. I have setup the package in maven and add the hibernate
Session to all constructors of my services.
I started with my CustomerService getting and setting my customerbeans
(each of them having a Set of AddressBeans). After first time saving a
customer, everything works fine. If i do the saveOrUpdate again in a
second request (because i want to change something), i got:
/*"Illegal attempt to associate a collection with two open sessions"*/
I googled a lot, but i do not find the answer??
I thought the tapestry-hibernate module open one session per request? It
seems so that the session from the previous request is still open?
*service -->*
public class CustomerFactoryImpl implements CustomerFactory{
private Session hibernateSession = null;
public CustomerFactoryImpl(Session session){
this.hibernateSession=session;
}
public void setCustomer(Customer customer) {
hibernateSession.saveOrUpdate(customer);
}
}
*page -->*
public class CustomerData {
@Inject
private CustomerFactory customerFactory;
@ApplicationState
private Customer _customer;
public void onSuccess(){
customerFactory.setCustomer(_customer);
}
}
*bean --->*
@Entity
public class Customer{
@Id
@GeneratedValue
private long id;
... lots of simple attributes
@OneToMany
@Cascade(CascadeType.ALL)
private Set address= new HashSet();
access methods to addresses ...
}

tapestry hibernate problem
Hi,
i have tried the tapestry-hibernate package to handle my hibernate
sessions. I have setup the package in maven and add the hibernate
Session to all constructors of my services.
I started with my CustomerService getting and setting my customerbeans
(each of them having a Set of AddressBeans). After first time saving a
customer, everything works fine. If i do the saveOrUpdate again in a
second request (because i want to change something), i got:
/*"Illegal attempt to associate a collection with two open sessions"*/
I googled a lot, but i do not find the answer??
I thought the tapestry-hibernate module open one session per request? It
seems so that the session from the previous request is still open?
*service -->*
public class CustomerFactoryImpl implements CustomerFactory{
private Session hibernateSession = null;
public CustomerFactoryImpl(Session session){
this.hibernateSession=session;
}
public void setCustomer(Customer customer) {
hibernateSession.saveOrUpdate(customer);
}
}
*page -->*
public class CustomerData {
@Inject
private CustomerFactory customerFactory;
@ApplicationState
private Customer _customer;
public void onSuccess(){
customerFactory.setCustomer(_customer);
}
}
*bean --->*
@Entity
public class Customer{
@Id
@GeneratedValue
private long id;
... lots of simple attributes
@OneToMany
@Cascade(CascadeType.ALL)
private Set address= new HashSet();
access methods to addresses ...
}
It seems so simple, but i don't know whats going wrong? Anyone an idea?
Thanks a lot,
Thomas
