Hey Martin,
thanks for the quick response. It sounds quite good, but it is not working yet.
Since we use guice, I tried to use the WebApplication we have
configured already:
final WicketTester wicketTester = new
WicketTester(WebApplication.get());
wicketTester.startPage(pageClass,pageParameters);
return wicketTester.getLastResponseAsString();
But I get following exception[1].
Some more basic conditions.
* A request is currently running.
* I need to get session information into the rendering, since the data
loading for the page contains authorization checks on the currently
logged in user.
Any suggestions?
Stefan
