Dear All,
Pier (or any other seaside application) no longer needs a specialized
root component in order to use ShoreComponents. The Seaside28Jetsam
package now includes a ShoreHelperHelper which can be enabled in your
pier app configuration.
The "Helper" portion of Jetsam is entirely self contained, so could be
distributed separately.
The goal of the helpers concept is to avoid having to use specialized
root classes for generic additions which results in combinatorial
problems for multiple such additions.
Helpers are Decorations which are automatically added to the root
component of any application subject to configuration options. They work
similarly to other Plugins in Seaside 2.8, as in, you can provide
additional Helpers by subclassing WAHelper.
So far, in addition to the "Shore Components Helper", Jetsam implements
a "Keep Alive Helper" for keeping the session alive while the users
browser is open. I find the later totally indispensable.
Next I am looking to see how a similar mechanism can be used to avoid
needing to subclass WASession. I aim to support Magma as a helper so
that all of the different options for shared or pooled magma sessions
can be orthogonal to the choice of seaside session class. If Comet could
be added as a helper as well then that would also be great.
best regards
Keith
