Hello,
I have many problem upgrading from tap 3 to tap4, maybe someone
already encountered those problem:
1/ HIVEMIND: Order for threaded service cleanup
I have threaded services that are dependant of each other.
HibernateSessionFactory which implements ServiceImplementationFactory
and a custom interceptor for hibernate.
The interceptor is also declared in hivemind as a threaded service
"auditLogInterceptor", this interceptor gets injected another
threaded service CurrentPrincipal. When I start the application, the
services are constructed in the following order currentPrincipal then
auditLogInterceptor and then the session from
HibernateSessionFactory. But when the thread cleans, in
HibernateSessionFactory I have registered a notifier to commit the
transaction if necessary and to close the session. The problem is
that the currentPrincipal service and auditLogInterceptorService get
cleaned before the notifier, thus calling the notifier and committing/
closing the session creates a brand new clean auditLogInterceptor and
currentPrincipal (Thus I loose all the state)! What can I do to
avoid this. I have searched the web and have seen someone with a
similar problem, but James Carman seems to said that was maybe an
issue with hivemind.
Do you have an idea??? PLZZZZZZZZ
2/TAPESTRY: Creating form components containing a template
encapsulating other component.
In tap3 I had some kind of virtual form components that consisted in
a baseComponent implementing IFormComponent (so fieldlabel could work
with them) that consisted of an input text and an image (The
component wraped all parameters of textfield). That was a bit of a
hack but worked ok. But with tap4 the same components don't work
anymore because tapestry is generating two field ids one for the
wrapper and one for the contained component!
What would be the best way to do form component that have a template
and encapsulates other components.
Thanks for you help !
Numa
