    A new maintenance release of the E2E BRIDGE has been released. With this edition of our E2E Developer Newsletter we inform you about the latest features and bug fixes of the E2E BRIDGE software components. As usual, you find all details in our release notes that are provided in our Online Documentation.

    Compatibility Hints

    With this and previous RUNTIMEs, we changed the RUNTIME behavior regarding navigating to and comparison with NULL values. This was necessary, because some comparisons did not return a correct result.
    Before, the RUNTIME ignored this – now, if the service is recompiled, the RUNTIME will log an error to the bridgeserver log in both cases.

    local int = myNullObject.index
    aValidString > myNullString

    Both fixes reveal model errors, but often these errors do not matter in practice.

    • The correct behavior would be to throw an exception (RUNTIME 2018.2 and 2018.4), but this resulted in services to stop unexpectedly that have been running fail-less for years.
    • We improved this by logging an error instead of throwing an exception (RUNTIME 2018.6 and 2018.7).
    • Apart from these errors, there would be no reason to change the services (and often no budget, too). So, finally (RUNTIME 2018.10), we decided to log the corresponding errors only, if services are recompiled. If a modeler is working on the service anyway, he will see the errors and can easily rectify the model, e.g. like:
      • local int = myNullObject.index if

        Also do something in case int did not get initialized.
      • myNullString.exists() and aValidString > myNullString

    Please be aware of these facts, if you are updating your RUNTIME. We recommend updating to RUNTIME 2018.10, and not use the RUNTIMEs between 2018.2 and 2018.9.
