I have developed a VF page which needs to do 3 call outs to external system in a sequence. The wsdl has been shared for these web services. We have implemented the continuation pattern based for wsdl call out as per the link. However I am not able to chain them. I could chain it using on complete on action function to chain the calls but it requires a round trip back to the browser which i wish to avoid. Any suggestions will be greatly appreciated. Thanks in advance
In the process response method of first callout you have to make second Callout Continuation instance.
