Improvements for Web Components

[marschall]

Improvements that allow applications with Web Components to run with a lower overhead.

• Save only a single action continuation. Since the back button does not work with Web Components in general we only need to save a single action continuation. This should keep sessions smaller.
• Dedicated action continuation. Since the back button does not work with Web Components in general we can make use of an optimized action continuation that:
  • does not redirect.
  • does not capture state.
  • does not restore state.

In theory these classes could be used in general for "back button less" Seaside applications. However this is quite an advanced topic so I think it's ok to "burry" these in the WebComponents package. Let me know what you think.

Is there a typo or two in https://github.com/marschall/Seaside/blob/master/repository/Seaside-WebComponents-Core.package/WAHeadlessComponent.class/README.md ?

Also, I wouldn't mind if the classes that are useful for SPA's are not buried, but more generally available. Perhaps in a SPA package?

Probably a rendering issue by GitHub. Check out the raw content

What classes would you be interested in? WAWebComponentActionContinuation? Do you have a suggestion for a name?

Perhaps in a SPA package?

Maybe, but only if we have more than one class to go there.

Got it. Thanks

If I understand things correctly, i see

• WAWebComponentActionContinuation
• WASingleElementCache
• WASingleContinuationSession

as candidates.

Maybe something like Seaside-SingleContinuation-Core as a name? Or maybe rename Seaside-WebComponents-Core as such?

Cheers, Adriaan.
