SDL WEB 8 Save Component event couldn't be triggered

Question

The OnComponentSave Event couldn't be triggered and no error is raised.

Below is the detailed code. The "initialized" and "event be subscribed" info can be found inside the Application log, but the "save component completed" message never is displayed. No other error or warning can be found neither. Any idea what's wrong here?

[TcmExtension("My Tridion Event System")]
public class Events : TcmExtension
{
    public Events()
    {
        Logger.Instance.LogInfo("Initialized");
        Subscribe();
    }

    public void Subscribe()
    {
        try
        {
            EventSystem.Subscribe<Component, SaveEventArgs>(OnComponentSaved, EventPhases.Initiated);
            Logger.Instance.LogInfo("Event be subscribed");
        }
        catch (Exception ex)
        {
            Logger.Instance.LogError("Error : " + ex.Message);
            throw ex;
        }
    }

    private void OnComponentSaved(Component component, SaveEventArgs args, EventPhases phase)
    {
        Logger.Instance.LogInfo("Save component started");
    }

}

Answer 1

You do not say in your question that you have actually saved a component to test this. I'm going to assume that you have, but it's also possible that the server where you saved the component is not the one where you have the events system installed/configured.

This could easily happen in a scaled-out scenario.
