mohierf commented 8 years ago

As reported by @spea1

WebUI host properties not working if only Global Service & Host Event Handler is enabled (Webbrowser say Error: 500 Internal Server Error)

But host and service properties is working if Global Service & Host Event Handler is enabled!

What is happening is due to the fact that event handler is enabled for an host, but no event handler command is defined for this host. I suppose that Alignak is using the globally defined event handler command to run an event handler for the hosts that do not have their own ...

But, when the WebUI is displaying the host properties page, no verification is done to check if an event handler is really available for this host.

Note that it should be the same behaviour for some other host/service parameters ...
