An annotation attribute that is defined as an array does not have to have
the curly braces to define a single value for that attribute.
Basing a Java API for configuration on XML syntax is a poor implementation.
Why not support the entire XML configuration syntax in the annotation? Java has
APIs to express a collection of items. It is much easier to utilize an array
than a comma separated value attribute. The array allows the developer to
clearly express their intent. Utilizing an array does not require parsing when
the configuration value is accessed.

> Key: WW-4590
> URL: https://issues.apache.org/jira/browse/WW-4590
> Project: Struts 2
> Issue Type: Improvement
> Components: Plugin - Convention, XML Configuration
> Affects Versions: 2.3.24
> Reporter: Aleksandr Mashchenko
> Assignee: Aleksandr Mashchenko
> Fix For: 2.5
>
>
> Allow to use multiple values in {{result}} tag {{name}} attribute and in
> {{Result}} annotation {{name}}.
> So this typical configuration:
> {code:xml}
> <action name="save">
> <result>success.jsp</result>
> <result name="error">input-form.jsp</result>
> <result name="input">input-form.jsp</result>
> </action>
> {code}
> Can be shorten to that:
> {code:xml}
> <action name="save">
> <result>success.jsp</result>
> <result name="error, input">input-form.jsp</result>
> </action>
> {code}
> And this annotations:
> {code:java}
> @Action(results = {
> @Result(name="error", location="input-form.jsp"),
> @Result(name="input", location="input-form.jsp"),
> @Result(name="success", location="success.jsp")
> })
> {code}
> To that:
> {code:java}
> @Action(results = {
> @Result(name="error, input", location="input-form.jsp"),
> @Result(name="success", location="success.jsp")
> })
> {code}
