Hi,
I tried QueryStringUrlCodingStrategy and MixedParamUrlCodingStrategy and
both are throwing
exceptions. I looked at the example in chapter 15.2 , I don't get the point
of:
((WebApplication)getApplication()).unmount("cheeses");
((WebApplication)getApplication()).mountBookmarkablePage("cheeses",
CheeseDetailsPage.class);
((WebApplication)getApplication()).unmount("cheeses");
((WebApplication)getApplication()).mount(new
QueryStringUrlCodingStrategy("cheeses", CheeseDetailsPage.class));
((WebApplication)getApplication()).unmount("cheeses");
((WebApplication)getApplication()).mount(new
MixedParamUrlCodingStrategy("cheeses", CheeseDetailsPage.class, new
String[]{}));
why mount and unmount?
The exceptions are thrown after the first on timer event.
QueryStringUrlCodingStrategy gives:
Root cause:
java.lang.NullPointerException

Any ideas?
