> Key: WW-4482
> URL: https://issues.apache.org/jira/browse/WW-4482
> Project: Struts 2
> Issue Type: Bug
> Components: Expression Language, Value Stack
> Affects Versions: 2.3.20
> Reporter: Jasper Rosenberg
> Assignee: Lukasz Lenart
> Priority: Critical
> Fix For: 2.3.24
>
>
> This definitely worked before 2.3.20, but unfortunately I haven’t been able
> to track down the actual source of the bug introduced for 2.3.20. My best
> guess is that it was introduced when the code was refactored to support
> Collections.
> Basically I have an Action, with a setter and getter for state that uses a
> custom type convertor like so:
> {code:java}
> /** @return the state. */
> @TypeConversion(converter = "com.myco.typeconvertor.RegionTypeConvertor")
> public RegionI getState() {
> return state;
> }
> {code}
> When I submit the action, this type convertor is correctly used to turn the
> “state” post parameter into a RegionI object which is injected into the
> Action. So far so good.
> However, the result looks like:
> {code:xml}
> <result name="selfSignupFlow" type="redirectAction">
> <param name="actionName">confirmAccount</param>
> <param name="streetAddress">${streetAddress}</param>
> <param name="city">${city}</param>
> <param name="state">${state}</param>
> <param name="postalCode">${postalCode}</param>
> ...
> </result>
> {code}
> And in the latest release, when it evaluates $\{state} it uses the default
> type convertor (in this case for an enum because the concrete class is a
> USState enum), rather than the com.myco.typeconvertor.RegionTypeConvertor
> specified on both the getter and setter for state in the action.
