[Tapestry 5] CookieSink Implementation

[chan Alfred <al...@gmail.com>]

Hi All,

I am trying to use org.apache.tapestry.services.PersistentLocale to
explicitly set the locale of the page regardless of the Client browser
locale.

But, I found that Null Pointer exception was thrown when I call

PersistentLocale.set(Locale.ENGLISH);

Aftert looking the source code, it seems that the CookieSink has not been
implemented in org.apache.tapestry.services.TapestryModule.
Am I correct?

Regards,
Alfred


P.S. The following is the exception thrown from Tapestry 5.
