Content (please ensure you mask any confidential information):

Hello,

I have been trying to use webservices in order to export taleo onboarding data, but I get the following error :

<faultstring>The attribute "version" value "http://www.taleo.com/ws/tr800/2009/04" is not supported by the export service.</faultstring>

I know that the problem resides in the model I'm using :

model="http://www.taleo.com/ws/tr800/2009/04" projectedClass="TransitionProcess".

This model have been extracted via a TCC script (the source code).
So my question is : is it possible to export onboarding data via webservices ? and if yes with which model ?
