Are you defining your own ComponentRequestFilter interface? As you have included the code for that I am assuming you have.
You have to implement Tapestry's ComponentRequestFilter, not your own as you can't contribute to the RequestHandler any other implementation. regards Taha On 06-Aug-2013, at 5:53 PM, Will N. <llcool_wil...@yahoo.fr> wrote: > Am 06.08.2013 14:13, schrieb Thiago H de Paula Figueiredo: >> I'm sorry, I should have asked for your ComponentRequestFilter >> implementation source too. ;) >> >> On Tue, 06 Aug 2013 08:31:15 -0300, Will N. <llcool_wil...@yahoo.fr> wrote: >> >>> Am 06.08.2013 13:25, schrieb Thiago H de Paula Figueiredo: >>>> On Tue, 06 Aug 2013 05:10:37 -0300, Will N. <llcool_wil...@yahoo.fr> wrote: >>>> >>>>> Hi, >>>> >>>> Hi! >>>> >>>>> I am trying secure some pages of my application as shown in this >>>>> tutorial. http://tapestryjava.blogspot.co.uk/search/label/security >>>>> But I am having following error message when I start the application. >>>>> Since the RequiresLoginFilte class implements the ComponentRequestFilter >>>>> interface, I am confused about the coertion error! >>>> >>>> The error is weird.
