Hi, i have a problem with consume web service.

i already test on WCF client test , the value is exist, but in dynamics AX the value always null. i tried refresh , update, and deploy service reference in visual studio but still same.

to make sure, i create c# application and add wsdl to service reference, and the value is exist same with WCF client Test result.

what can i do for show same result with WCF client test ?

for information, wsdl link generated from OSB

thanks

RE: always get null value when consume web services

Hi Martin,

did you mean updating the service in visual studio same with this picture ?

If yes, i already take this action , deploy and recompile on AOT , but still not refresh on AX.

So I took action with deleted the bad service reference and add it again on this project.

I do not know why this happens, because usually if I have a new update on the link wsdl, I only update the reference services and will refresh on AX.
Maybe I got bad luck on last Saturday :)

That's a lot of information that we didn't get before...

Anyway, I'm glad you've solved it. By the way, updating the service reference in Visual Studio would probably suffice.

RE: always get null value when consume web services

Hi martin,

sorry if i tell you about this problem not clearly,

i get web service link from oracle service bus (OSB), and then they OSB team create modification on their wsdl.

i had consume wsdl for AX with add service reference on visual studio.

before modification wsdl link by OSB team, the record is still have null value, after they fix it, in WCF client test is running well with no null value, but in AX still same ,even though i had refresh , rebuild , deploy ,clear cache, cil, and compile c# project on AOT but still not changes.

so in yesterday, i tried make new C# project with same wsdl link ., and the result is good, i dont get null value anymore.

RE: always get null value when consume web services

You still didn't tell us what you're doing. I see from your code that you're consuming an external web service in X++ and you're probably calling the same service in the test client. Did I describe your situation correctly?

Unfortunately I can't say what service you call, whether you're really calling the thing or what other information we didn't get from you...

Without more information, the only advice I have for you is using debugging and tracing to identify exactly what's going on, such why the properties are not filled in or they lose values later. Just looking at the final result isn't usually enough to understand the problem.

Hi Davinius ,

Can you share with us what you are doing?

Is your service operation in AX having an outbound transformation through a XSL stylesheet? If yes, the WCF client will always return a null value.

I assume that serializing to the service operation return type is not working since the XML structure is no longer the same after the transformation.

Had the same issue a week ago, removed the outbound transformation and I did receive a return value.

Kind regards,

Wim.
