[jira] Commented: (WICKET-2685) MixedParamsUrlCodingStrategy
,classcastexception from Long to String
[ https://issues.apache.org/jira/browse/WICKET-2685?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12802138#action_12802138 ]
vineet semwal commented on WICKET-2685:
---------------------------------------
i see the same problem in Mixedparamhybridurlcodingstrategy.
this time i am getting same exception at line number 129 .
i have checked that in 1.4.5 and the snapshot,
String value = param instanceof String[] ? ((String[])param)[0] :
(String)param;//line number 129
following changed i did in custommixedhybrid*strategy,
String value = param instanceof String[] ? ((String[])param)[0] :
String.valueOf(param);
everything appears to be working..

> 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()
