[jira] Commented: (TUSCANY-3459) JSON-RPC (and other) binding fails
if Interface is marked as remotable only in the composite
[ https://issues.apache.org/jira/browse/TUSCANY-3459?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12832396#action_12832396 ]
Luciano Resende commented on TUSCANY-3459:
------------------------------------------
We have two issues here, one related to the incompatibility of the ComponentService (marked remote in the scdl) and the ComponentType (considered local) interfaces, and I have raised an issue with the OASIS Spec with a proposal to relax the interface compatibility check.
Another issue is that Tuscany checks the componentType interface in order to identify if any data binding transformation is required and when this interface is not annotated, it is considered a local interface and all databinding transformations will be skipped, failing the operation invocation.
