Hello,
Thought I'd post this here in case anyone else has the same problem.
I was modifying a fairly simple tapestry app and adding a scheduled
service with a PeriodicExecutor, the service did some database work that
was not being committed and there was no exception in the logs!
When I investigated I found that an exception was being thrown but never
reported, basically I had an interface that was package private and that
was causing an exception that was never getting reported.
I've made an example project that you can see
g...@bitbucket.org:jaybowers/tapestry-class-loading-issue.git and here is
the exception (that I had to get by stepping through the app):
[DEBUG] AppModule.SomeOtherPojo Invoking constructor public
example.tapestry.other.SomeOtherPojoImpl() (for service 'SomeOtherPojo')
[INFO] other.SomeOtherPojoImpl Let's create a bang...

I can get round this by making the interface SomeOtherPojo public but
its not ideal.
I've also included a link on the index page of the app to create the
exception without the scheduler.
HTH,
Jay
