      Description

      Hi again,

      It has been a long time without any response to these issues we had as
      Beezon with FIWARE Enablers.

      We bypass some of them like refreshing IE close the IE and again login
      whenever we made a change into a FIWARE Lab but still we had issues with
      CEP.

      More specifically for CE

      a) The delete context menu does not work,
      b) Importing a project from a previous saved definition does not render
      well to the UI.
      c) The save button also does not update the definition.
      d) There is not a complete tutorial of using the WebUI in a new CEP. There
      are some video tutorials, showing glimpses of defining an event, EPA, etc,
      but not an end to end scenario, and how to update the server of using the
      new definition.
      e)The only way, it was finally possible to use a new project was this,
      create a new project, add the events, consumers,context, EPAs.
      export definition to a file for back up.
      Export definition to server.
      Updating with the REST Api the definition to use.
      Success in posting a new event and getting a callback to another rest
      consumer.
      And all that worked for the deleted instance after a lot of hours spent on
      trying and retrying.

      Any news, or suggestion for these problems,

      Best Regards,

        Thank you for using the CEP GE, sorry you had your instance deleted.

        As for your issues:
        a) The delete definition option should work. In order to open a bug on it, please describe a scenario in which it doesn't

        b) Again, I'm not aware of this issue. If you want us to open a bug for it, please send us the project and on which CEP instance you run it on (if it is based on an image, please send us the image name).

        c) The save button updates the definition in the UI repository. It doesn't export it to the engine, and the engine is not aware on this update. You need to export it, and stop & start the engine to have it run with an updated definition,

        d) We plan to add a more advanced sample.

        e) The import should work. Beside that your steps are the right steps. You should export to a file for a back up, you should export the definition to the engine repository, you should update the engine to work with the saved definition (if you changed the definition name from the previous run), you should stop & start the engine to have it run with the new definition.
