Re: T4.1.2 / Spring 2.0.6 / Hib3 Lazy loading and PropertySelectionModel stuff

RE: T4.1.2 / Spring 2.0.6 / Hib3 Lazy loading and PropertySelectionModel stuff
I also experienced some grief (4.0.x) with PropertySelectionModel when using Hibernate. The behavior also changed between the PropertySelection component and the Palette component because they use(d) different techniques to find the matching item. A good equality test and the tacos BeanPropertySelectionModel cleared up my problems.

Re: T4.1.2 / Spring 2.0.6 / Hib3 Lazy loading and PropertySelectionModel stuff
Not sure about the best solution, but we use:
public static Class checkForCGLIB(Class type)
{
if (type.getName().contains(CGLIB))
{
return type.getSuperclass();
} else return type;
}

Hi,
I'm witnessing some 'interesting' behavior, using lazily loaded
collections (Hibernate) combined with PropertySelectionModel
stuff. Before
getting into too much detail - using my JUnit tests I can prove that
traversing the (nested) objectgraph actually has the information
(albeit
via CGLIB proxies). When using this in my T4.1.2 page however, I
see that
the correct poplist value doesn't get selected. In a read only
version of
the page on the other hand - where the poplist is dynamically
replaced by
a readonly display item - the information is shown.
Is there something that I should be aware of in using T4/Hib3
regarding
the selectionmodel component?

Re: T4.1.2 / Spring 2.0.6 / Hib3 Lazy loading and PropertySelectionModel stuff
One thing to be aware of is that the same db-row, in two different Hibernate-Session, corresponds to two different objects. So with session-per-request, if your PSModel is loaded in one request, and your value-parameter-object in another. If you don't override Object.equalsappropriately, Tapestry cannot know which list member to show for a given value. 2007/8/28, Jan Vissers [EMAIL PROTECTED]: Hi, I'm witnessing some 'interesting' behavior, using lazily loaded collections (Hibernate) combined with PropertySelectionModel stuff.
