> XWorkBasicConverter doConvertToCollection causes ClassCastException if an

> Key: WW-3762
> URL: https://issues.apache.org/jira/browse/WW-3762
> Project: Struts 2
> Issue Type: Bug
> Components: Value Stack
> Affects Versions: 2.3.1.2
> Reporter: Pelladi Gabor
> Assignee: Lukasz Lenart
> Labels: patch
> Fix For: 2.3.2
>
> Attachments: WW-3762.diff, WW-3762.patch, example.txt
>
>
> My action has a property of type List<Integer> (same for other non-string
> types). The action will later iterate over this property, and it gets a
> ClassCastException, because the list (of type List<Integer>) contains a
> String.
> It is because XWorkBasicConverter.doConvertToCollection() converts the input
> string array into an integer list. But if the input coming from the browser
> contains a value that cannot be converted to a string, then the string
> "ognl.NoConversionPossible" is put into the list. It is wrong, we should pay
> attention to the type of the list.
> I have attached a patch that does not put elements into the list that cannot
> be converted.
> I have also attached a file that contains a simple example for this bug.
