I've worked around the problem inconsistent JSON results by removing the
root parameter from the JSONResult annotations. It appears that
at least I'm getting consistent results this way:
@Results( {
@Result(name = "jsonPopsResult", type = JSONResult.class, value =
"", params = {"noCache", "true"}),
@Result(name = "jsonRefugesResult", type = JSONResult.class, value
= "", params = {"noCache", "true"})})
The params attribute was previously
params = {"root", "jsonResult", "noCache", "true"}
Fortunately, the jsonResult property on the action is the only
non-base-class property, so I'm still returning only what I need.
FYI, as was suggested, I tried configuring the action via xml instead of
annotations, but for some reason couldn't get the
action's results to be recognized:
<package name="wizard" extends="myapp" namespace="/wizard">
<action name="mapQuery"
class="gov.doi.myapp.actions.wizard.MapQueryAction">
<result name="jsonPopsResult" type="json">
<param name="root">jsonResult</param>
</result>
<result name="jsonRefugesResult" type="json">
<param name="root">jsonResult</param>
</result>
</action>
</package>
I got "No result defined for action
gov.doi.myapp.actions.wizard.MapQueryAction and result success". Probably
some
stupid error on my part, but I don't have time to work on it further right
now. If I ever ascertain that the problem goes away
with xml config, I'll let the list know.

I am not passing in JSONResult to the action. The parameters passed
(since I suspect you'll ask :-) are

For what it is worth, the XML files appear below, edited to remove/change
irrelevant and security sensitive areas
There is no struts-config.xml. I'm using the struts-default.xml from the
core jar.
