You're welcome :) Sorry I thought you don't need keys. If you needed
them, then following would work:
public Map<String, List<MyObject>> getResult() {
return result;
}
<param name="includeProperties">
^result\.[^\[]+\[\d+\]\.interestingProperty$
</param>
Then only limitation of this one is that keys should not contain [
character because of [^\[]+ which I had to use instead of .* to avoid
including all of the model.
Kind Regards.

Thanks, that indeed works Yasser.
However, with that configuration I won't have access to the map keys,
which I also need. For now, I created a new getter that retrieves only
the keys, but this is a workaround.
However from what you said, I guess it is not possible to have both the
keys and values filtered in a map structure as I originally wanted, right?
Thanks again for your help,

Hi Micael, thanks for your report!
You're right! I debugged Struts with your model, Map<String,
List<MyObject>>. I realized with following sample initialization:
MyObject mo = new MyObject();
mo.setInterestingProperty("IP");
mo.setNotInterestingProperty("NIP");
ArrayList<MyObject> mol = new ArrayList<MyObject>();
mol.add(mo);
result = new HashMap<>();
result.put("first", mol);
Struts checks result.first[0].interestingProperty if it has any
includeProperties matches.
The map key can be any string i.e. .* Consequently you have to have
result\..*\[\d+\]\.interestingProperty but .* causes including all of
the model -- because Struts splits above into multiple regex: result,
result\..*, result\..*\[\d+\] and result\..*\[\d+\]\.interestingProperty
and checks input with them respectively. The second one passes all!
I just could find following workaround which you might like:
private Map<String, List<MyObject>> result;
public Collection<List<MyObject>> getResult() {
return result.values();
}
<param name="includeProperties">
^result$,^result\[\d+\]\[\d+\]\.interestingProperty$
</param>
Hope this helps!
Best.

Hello Yasser, thanks for your reply.
It did not work. The configuration you suggested, sends nothing in JSON
object.
I also tried this configuration:
<param name="includeProperties">
result\..+,
result,interestingProperty
</param>
But it sends all properties, including notInterestingProperty.

Subject: JSON plugin: filter fields in a Map with Lists
Hello,
In MyAction, I have the following instance variable:
Map<String, List<MyObject>> result;
And MyObject has the following properties:
MyObject
|- interestingProperty
|- notInterestingProperty
I want to return the action result as a JSON. So, in my struts
configuration I have:
<action name="MyAction" method="execute" class="myAction">
<result name="success" type="json">
<param name="includeProperties">
result\..+$
</param>
</result>
</action>
This returns all keys/values in result map. But I want to write a
JSON with only
interestingProperty of each MyObject (which are in a list).
Hi,
Doesn't below work for you (to write only interestingProperty)?
<param name="includeProperties">
result,interestingProperty
</param>
Regards.
I've fiddled with the regular expression for a while, but could not
find a way to do
it.
Is it possible to achieve what I need?
Thanks,
