James Holmes updated WW-2909:
-----------------------------
Fix Version/s: 2.1.3
> Params will not always set all parameters in @Result annotation
> ---------------------------------------------------------------
>
> Key: WW-2909
> URL: https://issues.apache.org/struts/browse/WW-2909
> Project: Struts 2
> Issue Type: Bug
> Affects Versions: 2.1.3
> Reporter: Todd Perry
> Fix For: 2.1.3
>
>
> I have a custom result that implement Result with two setters for 'feedTitle'
> and 'feedDescription'. When using the @Result annotation:
> @Result(name = "feed", type = FeedResult.class, value = "feed",
> params = { "feedTitle", "testTitle",
> "feedDescription", "testDescription" }
> )
> The feedTitle is set but not feedDescription. The problem is in
> com.opensymphony.xwork2.ObjectFactory, buildResult, which calls
> OgnlReflectionProvider.setProperties with the map of properties... the map
> has this content:
> {feedTitle=testTitle, location=feed, feedDescription=testDescription}
> Struts appears to have added 'location' to the parameters when building the
> map. Since my Result does not have this property it throws an exception
> which is handled silently in buildResult but it does not set the remaining
> properties in the map (feedDescription).
> See my comment on WW-2297 (sorry I did not realize it was closed when I added
> this) showing that this also prevents properties like 'actionName' from being
> set under certain circumstances, which means WW-2297 does not seem to be
> fully fixed. The map order seems to be arbitrary (I assume it's backed by a
> hash map) so it is not possible to make sure the Result properties appear
> first to prevent the exception from interfering. So this problem also
> prevents me from using @Result to place arbitrary parameters on the value
> stack, which it appears to be meant for as well.
> A workaround for this is that I can add a 'setLocation' to my result to
> handle the location property.. but it does not solve the situation in WW-2297
> when trying to pass parameters to an internal result type like
> ServletActionRedirectResult.
