> @StrutsParameter enforcement resolves accessor names differently from OGNL
> --------------------------------------------------------------------------

> {{StrutsParameterAuthorizer}} has to decide which accessor OGNL will go
> through for a parameter name, and it derives that name differently from OGNL
> in two places.
> h3. 1. Setters for names like {{uRange}} (OGNL 3.4.14 and later)
> OGNL 3.4.14 (orphan-oss/ognl#652, backport of #644) resolves
> JavaBeans-compliant accessors: for a property {{uRange}} it tries
> {{setuRange}} first and {{setURange}} second. {{findBindableAccessor}} only
> looks for {{set}} plus the capitalised name, i.e. {{setURange}}.
> Two symptoms follow:
> * {{@StrutsParameter}} on {{setuRange}} has no effect: the parameter is
> rejected (fails closed).
> * On a ModelDriven action, an unannotated {{setuRange}} on the action is not
> seen as the action's own member, so the parameter takes the "declared on
> neither the model nor the action" fallback and OGNL binds it through that
> setter. The same family as WW-5709 (fluent setters).
> With OGNL 3.4.13, which Struts currently ships, OGNL never reaches
> {{setuRange}}, so this only appears once OGNL is upgraded - by Struts or by
> an application that overrides the OGNL version.
> h3. 2. Getters for nested parameters
> For a nested parameter the authorizer matches the {{java.beans}} property
> name. {{Introspector}} names the property of {{getURL()}} {{URL}}, while OGNL
> reaches {{getURL()}} for both {{uRL.host}} and {{URL.host}}. On a ModelDriven
> action an unannotated {{getURL()}} on the action therefore also takes the
> "declared on neither" fallback. This one is independent of the OGNL version.
> h3. Suggested fix
> Resolve accessors exactly the way OGNL does: try {{set}} (or {{is}} then
> {{get}}) plus each accessor base name in OGNL's order, first match wins, and
> normalise the root property with {{Introspector.decapitalize}} so the
> candidate list matches OGNL's for the parameter name as written. Bump OGNL to
> 3.4.14 in the same change.
> Found while upgrading to OGNL 3.5 (WW-5326).
