Re: wicket-guice HttpServletRequest

[Martin Grigorov]

Hi,

To be able to do this you have to know Guice internals.
HttpServletRequest is @Request scoped and since there is no http request in
unit/wicketTester tests Guice cannot provide it for you.

I guess that you can bind it manually in your TestModule so it will have a
global scope as workaround.

But your question is not for Wicket but Guice forums (if there are such,
because Guice is not very well maintained lately).
