    Cannot use generics in Errai RPC

    fvitorc Newbie

      Hi,

       

      Errai cannot handle generic methods. If I declare a remote service as:

       

      <A extends Action<R>, R extends ActionResult> R execute(A action)

       

      The RPCStub generated by Errai is:

       

      public ActionResult execute(Action _0)

       

      Then the GWT compiler fails with:

       

      [ERROR] Errors in 'generated://786F5E4D45EAB85B5D2D81DBDE4686F4/org/jboss/errai/bus/client/ext/ExtensionsLoaderImpl.java'

         [ERROR] Line 56:  The type DispatchServiceImpl must implement the inherited abstract method DispatchService.execute(A)

         [ERROR] Line 80:  Name clash: The method execute(Action) of type DispatchServiceImpl has the same erasure as execute(A) of type DispatchService but does not override it

       

      I believe that there is no solution to that, but maybe my knowledge of generics is not so good.

      Does anyone know if it is possible to solve this problem?

       

      Regards,

      Vitor.
