Ivo Ladage - van Doorn commented on AMDATU-200:
-----------------------------------------------
@Angelo: I noticed that you committed a patch for this issue on the trunk. The
fix is to introduce a new base class 'ServiceDependentActivator' which ensures
that the Activator is not started before the JaxRsSpi service is available,
which is made available by the Wink registration service after setting the
proper RuntimeDelegate. Now this approach usually works, since the class that
instantiates CacheControl is a service and is thus not instantiated before the
Activator is started. However if I would instantiate CacheControl in the
Activator, the same error would appear. So even with this developer unfriendly
approach, there is no 100% guarantee that this always works. Furthermore, the
developer should not forget to us this special 'ServiceDependentActivator' as
base class of its Activator and to define the dependency with the JaxRsSpi
service in this custom activator.
For that reason I don't think this is the right way to go; there is still no
guarantee that the problem doesn't appear; we leave it up to the developer to
add specific code to workaround the issue, which in the end is not very likely
to occur.

> Components: Amdatu Web
> Affects Versions: 0.0.6
> Reporter: Ivo Ladage - van Doorn
> Assignee: Ivo Ladage - van Doorn
> Fix For: 0.1.0
>
>
> The current gadgets totally lack HTTP caching headers since JAX-RS does not
> provide any default caching headers. This should be added to all gadgets out
> there.
> The missing caching headers is most probably the reason why gadgets act so
> strange in IE8.
