How can I handle JSON response in Moqui inside a transition? - moqui

Question

I am actually making a JSON-RPC call to a transition from AngularJS. As the content type of the request is application/json, the input parameters are automatically made available in the context so I don't need to handle it explicitly.
Here is my request to 'getUsers' which is in the 'tutorial' component.
function($scope, $http) {
$http ({
url: 'tutorial/getUsers',
method: "POST",
data: JSON.stringify({username:'demouser1'}),
headers: {'Content-Type': 'application/json'}
}).success(function(response){
$scope.userList = response;
});
}]);
The code for the transition is written below
<transition name="getUsers">
<actions>
<service-call name="Tutorial.PartyServices.get#Users" in-map="context"/>
</actions>
<default-response type="none"/>
</transition>
The service looks like this
<service verb="get" noun="Users">
<in-parameters>
<parameter name="username"/>
</in-parameters>
<actions>
<entity-find entity-name="PersonAndUserAccount" list="userList">
<search-form-inputs default-order-by="firstName,lastName,username"/>
<econdition field-name="username" operator="equals" to-field-name="username"/>
</entity-find>
<script>ec.web.sendJsonResponse(userList)</script>
</actions>
</service>
Now to send JSON response I wrote ec.web.sendJsonResponse(userList) in the service itself. This makes the service tightly coupled with service calls that expect JSON as response. If I want to internally call this service i.e. in Moqui I would have to define another service.
So my question is can I handle this response in the transition which is making this service call?

Here is the sample available for mentioning JSON response in transitions. You can refer ExampleApp.xml.
Here is the code snippet for your reference.
<transition name="ExampleEntity" method="post">
<service-call name="org.moqui.example.ExampleServices.createExample" in-map="ec.web.parameters"
web-send-json-response="true"/>
<default-response type="none"/>
</transition>
HTH.
