    DMI.call failing

    I have an application which has been working successfully for 2+ years.

    I’ve created a new application by cloning the HTML and the module definition with a different name.

    The clone of the application with a new name works in all aspects except DMI.call.

    I’m guessing I’ve missed something in my cloning but I don’t know what it is and I don’t know where to look. So I need some pointers on where I can look.

    RPCResponse.getStatus() returns -90.

    Here is what the log says when I make the DMI.call:

    Code:

    To begin troubleshooting any kind of client-server comm issue, always start with the RPC tab in the Developer Console. -90 indicates a transport error, probably the IDACall Servlet hasn't been registered at all, or is registered at the wrong URL, so this request is just resulting in a 404 error.
