Thanks for your reply Howard.
I was thinking of some "external sync". But is it a "Tapestry way" ?
Maybe it would make sense to add kind of RenderSupport.addInitSingleton(...)
or
open up RenderSupport.getInit(String name) and check if it by yourself ?
I would then write one liner Tapestry.Initializer.AjaxLoaderUrl that would
address my js singleton problem.
