could you attach the code or a test case?

> When FormTester is used and you add a component to it, the logic in FormTester adds the component name and value into the MockHttpServletRequest (which will be a String as the key and a String as a value). My issue with this is that later, we have a RequestCodingStrategy which gets the parameterMap from the Request which its typed as <String, String[]>. When we iterate over this, we get a classcast exception when the String (From the form) is attempted to be converted into a String[].  I think something needs to improved in the Wicket Request object hierarchy to ensure this can't happen. For now I have just changed my logic in the RequestCodingStrategy to check for the String[] type.
