Hello all,
Hi!
I am trying to better understand how T5 components work and I would like
to know what the difference is between @Environmental and @Inject and
when to use which in the context of component developpement of course.
They're very, very, very different.
@Inject is one way to get services from the Tapestry-IoC registry.
@Environmental uses the Environment service, which is used for components
or pages to pass some information for components inside them.
For instance having a look under the hood of t:checklist, I noticed that
the validation tracker is injected by the @Environmental annotation as
follows:
*@Environmental*
*private ValidationTracker tracker;*
ValidationTracker is not a service.
whereas the javascript support variable is injected by the @Inject
annotation as follows:
*@Inject*
*private JavaScriptSupport javaScriptSupport;*
JavaScriptSupport is a service.
