Re: BrowserSnifferTool.init() not getting called from within Spring framework

[Claude Brisson <cl...@renegat.net>]

Yes, really strange.

And does the DispatchServlet properly call init(ViewContext) on other

One thought: you could try to see what happens when you put the sniffer
tool in the session scope (which happens to be more efficient by the
way).
