[jsr-314-open] Spec-Issue https://javaserverfaces.dev.java.net/issues/show_bug.cgi?id=1408

[Martin Marinschek]

Hi Ryan,

I don't think it is really cool to list all our applications' pages in
this exemption list - we are using dialogs, built on top of dynamic
includes, so we (at least) will have to find a workaround here.

In https://javaserverfaces.dev.java.net/issues/showvotes.cgi?issue_id=1313,
I suggest an (or better two) alternative courses of action. One of
them we should take, I believe. Find the issue text in the following:

1) (preferred) do as Facelets did before: treat the second
merry-go-round (application of tag-handlers) slightly different. Just
deal with new components (call mark initial state) and deleted
components (let them silently fall under the table, don't treat them
as dynamically removed components), and don't call onComponentCreated,
but onComponentPopulated if the component has been found. The
tag-handlers already expect this behaviour.

2) (performance intensive, not preferred) save partial state, recreate
the component tree and reapply partial state before rendering

regards,

Martin
