Indepenent of what the method looks like, why is it called more then once anyhow?
If there is the same method inside a page or component, I thought Tapestry retrieves all the data first and then "intelligently" parses all the pages and its component templates and notices if the same method is called several times? Now it seems like it goes through all templates line by line and then calls the methods every time it encounteres them without "an eye" for the page scope? If I define a class as threaded in Hivemind, doesnt Tapestry "know" that the method will always return the same result if it appears 100 times inside a page or component? If there is an injected method in some components and pages that references a threaded Hivemind class.....it is always the same call and therefore Tapestry would only need to call it once and use the same result for all components? Thanks!
