Lukasz Lenart updated WW-4336:

Comment: was deleted
(was: I briefly reviewed WW-1960 and this issue and for now I don't see simple
fix - basically you had been basing on buggy solution as action never can
receive {{Iterator}} via {{HttpServletRequest}}, if you'd want to use
{{someAction2}} as a standalone action it won't work because of that. It can
work only in this case, via {{<s:action/>}} tag)
> Action tag does not process list type parameters correctly

> Hello Everyone.
> While migrating application from struts 2.0.11 to 2.3.15.x encountered below
> issue -
> There is a list of objects available in a jsp, within which an action is
> invoked ( using s:action tag ) and that list is passed down for use in the
> callee action (this is being done to populate a table). This approach worked
> with struts 2.0.11, but with 2.3.15 - the list is being converted to string
> first before being passed to the callee action and is unusable by the time
> its received.
> With some debugging, figured out this piece of code was doing the conversion
> to string..
> {{ActionComponent.createParametersForContext()}}
> {code:java}
> String key = (String) entry.getKey();
> Object val = entry.getValue();
> if (val.getClass().isArray() && String.class ==
> val.getClass().getComponentType()) {
> params.put(key, (String[])val);
> } else {
> params.put(key, new String[]{val.toString()});
> }
> {code}
> relevant code snippet in jsp looks like this
> {code:html}
> <s:action name="someAction2" executeResult="true" namespace="/common" >
> <s:param name="iterable" value="#iter"/>
> {code}
> Is this an intended change in behavior ? I couldn't find relevant details in
> the release notes or the migration guide. What's the recommended approach to
> migrate such components ?
