Is it safe to share static components across multiple page instances and request threads?
Hi,
Is it threadsafe and "wicket safe" to share static Components across multiple instances of a Page (as well as across request threads) in wicket?
Say for example I have a BookmarkablePageLink that takes no dynamic PageParameter arguments, can I create this as a static class member and share it across all instances of the Page on which it is used? (instead if creating a new instance for each new page).
Rgs,
Joel

My guess would be no, since the object hierarchy of a page is a
fundamental aspect of Wicket. I don't think that instances of Wicket
Component objects are meant to be thread-safe and shared between
different Component trees. There is all kinds of mutable data in
Component that is not meant to be shared across threads. Creating a new
instance of the link for every page would be the correct approach.

(BTW I am assuming that since each component has a parent that sharing
is
NOT allowed)
