-----------------------------------
Could you prepare an example, Maven based?
I've tested with your code snippet and everything works, you don't have to
specify @TypeConversion at all, by default Struts2 will convert and create List
and User without any additional code.
ConversionRules should be removed, but thus can be done with new major version
-> 3.x
> TypeConversion annotation support improvement
> ---------------------------------------------
>
> Key: WW-3871
> URL: https://issues.apache.org/jira/browse/WW-3871
> Project: Struts 2
> Issue Type: Improvement
> Components: Plugin - Convention
> Affects Versions: 2.3.4.1
> Reporter: Pavan Ananth
> Fix For: 2.3.9
>
>
> The annotation support for TypeConversion in Struts 2 is too literal an
> interpretation of the XML support. For instance, I am required to supply this
> if I have choose the CreateIfNull feature at a property level :
> @TypeConversion(key="CreateIfNull_users", rule=ConversionRule.CreateIfNull,
> value="true")
> List<User> users;
> Given that the rule is CreateIfNull, the key can be constructed implicitly
> using property name - why is it asked of an user to type in the full key.
> This holds good for the other supported ConversionRules as well
