Hi all,

Does anyone have a solution to this?  I have exactly the same problem.  For
example:

<action name="ProductAction_*" method="{1}"
class="jp1980.actions.ProductAction">
<result name="list">/customer/products/list_ext.jsp</result>
<result name="json_list" type="json">
products, productsTotal
</result>
<result name="error">/error.jsp</result>
<result name="success">/missing.jsp</result>
</action>

products is a List.  If I specify products as the root, or specify no root
or includeParams and return everything from my action, products is returned
and populated fine in the JSON.  However, if i use the includeParams as
above, products is empty when I inspect the JSON.

Thanks for reading and kind regards,

James
