Problem with OpenSessionInViewFilter and Seam

[gustajz]

Hello!

I'm using Seam with Spring and Hibernate, but have problems with the OpenSessionInViewFilter/Spring.

The only problem is when I show in a list and access a lazy propertie, for example, then occurs the error of ?org.hibernate.LazyInitializationException: could not initialize proxy - the owning Session was closed?

Somebody already had this problem?
Exists some alternative to the OpenSessionInViewFilter?

Thank's

Below follows the throws.

[christian.bauer]

Do not use this filter. Use the TransactionalSeamPhaseListener in Seam for JSF and a Seam-managed persistence context. Both are explained in the Seam documentation.

[hstang]

One of the prime advantages you get from Seam is to avoid these kind of errors.

Like Christian said, SMPC is your friend.

[gustajz]

Yes,
modified all presistense classes for send the transaction control to Seam and now run perfectly.

However, I do not obtain correct configuration for the Seam to use dataSource from Tomcat Container, only from microcontainer, cannot fixed the DB connection configuration inside project (WAR).

Somebody has a suggestion, by another topic's not have?
I'm not using EJB3.

[gavin.king]

Don't use Tomcat's flakey datasource. The one in JBoss MC is much more robust.
