Hi, I'm having a problem with a ListView that displays an outdated list. In my test, the ListView uses a LoadableDetachableModel that "loads" from a static variable just to make sure the model is independent from any page instance. As far as I can tell, this problem has nothing to do with the model, but with the way Wicket prepares for a request listener invocation.
The exact setup is this: - the page contains a ListView and (outside of the list) a Link that adds an item to the list in its onClick(). The list itself is stored in a static variable. - the page is stateless - the page's components are created in onInitialize() Result: The list doesn't show the most recently added item. Reloading the original page shows the correct list. Note that by "reloading" I mean entering the page's URL since the browser's address bar now contains the request listener URL due to the page being stateless. This is how I think is happens: - Initially rendering the page works fine. The page is then discarded since it's stateless. - Clicking on the link creates a new page instance to invoke the link's request listener. - IPageAndComponentProvider.getComponent() cannot find the link yet since it is not created until onInitialize() has been called. - as a consequence, it calls page.internalInitialize() and internalPrepareForRender(false) - this creates the link, but it also creates the ListView and prepares it for rendering. This in turn polls the ListView's model and creates list items. It also marks the ListView as "prepared for render", which is the crucial point. - The link's request listener runs and adds an item to the list. - After the request listener handler, the page render handler runs - Tha
