Johan Compagner commented on WICKET-1578:
-----------------------------------------
Didnt we just fix this? we have now this code:
String value = param instanceof String[] ? ((String[])param)[0] : (String)param;
> MixedParamUrlCodingStrategy makes an incorrect assumption about
> RequestParameters.parametersMap of type String where as its String[]
> according to Servlet 2.3 and later

> MixedParamUrlCodingStrategy makes an incorrect assumption about
> RequestParameters.parametersMap of type String where as its String[]
> according to Servlet 2.3 and later
> Look at MixedParamUrlCodingStrategy.appendParameters (line 153) its type
> casting to (String) which throws ClassCastException at runtime since its of
> type String[].
> Same issue for decodeParameters.
> I actually have question about multivalued parameters. Will any of the URL
> schemes handle these correctly? if yes - is there an example that shows how?
