Struts2 Action being called twice if result type is json

Question

I have an Action class with 4 action methods. All four action action methods use a json result.

Via logging statements and debugging, I have verified that if I call action method 1, action method 2 and 3 are also called. But not 4. Finally, action method 1 is called again and the json result is generated

If I change the result type of Action method 1 to the default dispatcher with a jsp location, only action method 1 is called. (this is the behavior I want with the json result) Hope that makes sense.

Anyone have any ideas? This question was asked here https://stackoverflow.com/questions/3767698/struts2-if-result-type-json-and-method-defined-then-all-methods-get-invoked

But there was no answer. Please let me know if you need more information.

        this.theEmailList = theEmailList;
    }

    public List<String> getTheEmailList() {
        return theEmailList;
    }
}

In this action class, I attempting to call ajaxGetGoLiveEmailList, and what I get is ajaxGetGoLiveEmailList called first, and then ajaxGetChaserEmailList, and then ajaxGetAvailableEntityList, and then ajaxGetGoLiveEmailList gets called again. ajaxToggleGroupBusinessSubmitted is skipped.

If I change the result annotation of ajaxGetGoLiveEmailList to

results={@Result(location="something.jsp")

, only ajaxGetGoLiveEmailList get called.

When I look at the config browser, all the action mapping are configured correctly, pointing to the correct method calls.

Answer 1

JSON plugin may be calling all your methods that start with "get" in an attempt to serialize them for output. Try renaming your methods to something else.
