Major Description
i see classcastexception can't cast from Long to String at this line in a page(the url does not have page parameters) at line number 138 in mixedparameterurlcodingstrategy,
String value = param instanceof String[] ? ((String[])param)[0] : (String)param;//line number 138
cast in else can be clearly avoided,
String value = param instanceof String[] ? ((String[])param)[0] : param.toString();// ie. cast changed to tostring()
i tested that on my custommixed*strategy in which above mentioned is the only change,
everything appears to be working,
original exception in mixedparamurlcodingstrategy i got is as following :-
java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.String
