Unit Testing Application with custom HttpServletResponse

[Jan Ferko]

Hi everyone,

We use proxy around HttpServletResponse in our application. I would like 
to test components/pages using WicketTester, but when WicketTester tries 
to startPage it throws following exception:

java.lang.ClassCastException: myPackage.HttpServletResponseProxy cannot 
be cast to org.apache.wicket.protocol.http.MockHttpServletResponse
    at 
org.apache.wicket.protocol.http.MockWebApplication.postProcessRequestCycle(MockWebApplication.java:555)
    at 
org.apache.wicket.protocol.http.MockWebApplication.processRequestCycle(MockWebApplication.java:507)
    at 
org.apache.wicket.util.tester.BaseWicketTester.startPage(BaseWicketTester.java:319)

This is of course correct because our proxy implementation is not 
MockHttpServletResponse. Is there any workaround this problem?

Thanks for help.

Jan
