Don Brown updated WW-2297:
--------------------------
Fix Version/s: (was: 2.1.4)
2.1.3
> Using ServletActionRedirectResult (within @Result) and extra parameters.
> ------------------------------------------------------------------------
>
> Key: WW-2297
> URL: https://issues.apache.org/struts/browse/WW-2297
> Project: Struts 2
> Issue Type: Bug
> Affects Versions: 2.0.11
> Reporter: David Artiga
> Fix For: 2.1.3
>
>
> Given the following class and annotations:
> @Results(
> @Result(name = Action.SUCCESS, value = "myAction",
> type=ServletActionRedirectResult.class, params = { "param1", "value1" })
> )
> public class MyAction implements Action {
> ...
> }
> In method 'buildResult' from 'com.opensymphony.xwork2ObjectFactory' class:
> if (resultClassName != null) {
> result = (Result) buildBean(resultClassName, extraContext);
> try {
> OgnlUtil.setProperties(resultConfig.getParams(), result,
> extraContext, true);
> } catch (XWorkException ex) {
> ...
> }
> ...
> }
> When dealing with the readult an ognl.NoSuchPropertyException is thrown for
> property 'param1'.
> This is not a problem if the action is mapped using a XML file, because
> "actionName" property has been set earlier (resultConfig.requestParameters =
> { "actionName=myAction","param1=value1"}).
> But when using annotations, the requestParameters order changes(
> {"param1=value1", "actionName=myAction"}), so when throwing the exception
> "actioName" has not been set yet, and then the Result created has no
> actionName (=null).
> That causes a NullPointerException when trying to process the result.
> Possible patch (inform Ognl to not throw exceptions when setting properties):
> OgnlUtil.setProperties(resultConfig.getParams(), result, extraContext, /* -->
> */ false /* <-- */ );
