How to use "useReturnValue"

I am assuming you are talking about an 'invoke' operation. The response object should have a property called _retVal with the value returned, if any.

How do you access the retVal? There seems to be no response object.

I think you will need to give me more context/details on what you are trying to execute (which operation type, from JavaScript? from a service? etc). Also, there is information in the "Mobile Applications" book on the use of _retVal.

If you are using it from the Mobile AppBuilder and JSDO's, you can do it something like this in the event for an error:

------------

var errResp = JSON.parse(jqXHR.response);

console.log(errResp._retVal);

=======

This is taken from the "Run JavaScript" action of the "error' event of a JSDO read.

By the way, the JSON returned if its an error is something like this for an error returned by a rather default JSDO read operation with a return error in it:

--------------

{"_retVal":"This is the error","_errors":[{"_errorMsg":"ERROR condition: The Server application has returned an error. (7243) (7211)","_errorNum":0}]}

========

Hope this makes some sort of sense (I found it tricky to write up ;-) ).

Hi Phillip,

How would I do that on success? I am needing to set a local storage variable to that return value. I used that same code you sent me except i changed your "console.log" to "alert", on success of the login service. It is displaying the errors correctly but on success no message comes up.

Does anyone have a solution to my previous post?

Hmmm..... that I haven't tried. Have you mapped the return value in the service definition in PDSOE? If I get a chance, I will have a look at it.

Nope, not sure on how to map the return value because it doesn't display in the response.

Can you tell us exactly what operation you are performing and trying to get _retVal. If it's an invoke operation, it should work for you. I just confirmed this.  The response object had a property called _retVal with the value returned.

If you're trying to do with a CRUD (Create, Read, Update, Delete) operation, it's not going to work. For these operations, we are not returning a response object.

The mapping I am talking about is in the "Define Service Interface":

Let me know if this helps. (As I said, I haven't actually tested this on the mobile side)

I tested an invoke operation on the mobile/client side and got back the _retVal in the response object for a successful transaction. Would like to know which operation  the original post-er was trying to get the _retVal for, as it's not supported for the CRUD operations.
