[jira] [Commented] (TUSCANY-3932) Callbacks don't work in the
distributed domain
[ https://issues.apache.org/jira/browse/TUSCANY-3932?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13179567#comment-13179567 ]
Simon Laws commented on TUSCANY-3932:
-------------------------------------
I've been looking at this an I also note that there is code in the CallbackServiceReference that resets the binding on the original callback endpoint reference rather than the cloned version which doesn't sound right. Also after the clone the binding provider isn't reset so in effect the binding provider, and associated wires, are shared between all callback references for a particular component. I suspect that this will cause problems for concurrent requests to the component.

> The callback wire calculation currently requires knowledge of the service runtime. This will not be available in the distributed case where the Endpoint matched by and retrieved from the registry will not have a built runtime behind it. We need to refactor this based on the configuration available in the SCDL written to represent a remote Endpoint.
> Of particular interest is callback bindings that are generated vs callback bindings that are specified by the user. If a user specifies a binding this should automatically be available in the reference node as it will be written be default when the Endpoint is written out. Automatically generated callback bindings, usually generated to match the forward binding, won't be in that list and won't get written out so we need to address that.
