SignatureANGProcessor call from portal widget

[Kelly Logan]

Yet another layer of the signature pad saga! 

On the /fsmcp portal, the "FSM Task Sign Pad" widget is used to display the signature pad. When the 'Accept and complete' button is clicked, the information is bundled up and handed off to some post call (see below for details). 

Can anyone point me to where or even what "SignatureANGProcessor " is? I don't see anything similar in Scripted REST APIs, REST Data Brokers, listed in the REST API Explorer, nor in Scripted SOAP Services.

No reference I can find to it anywhere in docs or community. It seems likely it's an Angular call of some kind, but I'm not sure how to track that down in our system. 

Any ideas?

    c.doSaveSignature = function(actionName, table, document, image, data, signed_name, acknowledgmentText) {

        var params = {
            action: actionName,
            table: table,
            document: document,
            getAttachmentId: true,
            sp: true,
            time: new Date().getTime(),
            acknowledgement_text: encodeURIComponent(acknowledgmentText),
            signed_name: signed_name
        };

        var payload = {
            image: image,
            data: data
        };

        var dataURL = '';
        Object.keys(params).forEach(function(t) {
            dataURL += "&" + t + "=" + params[t];
        });

        return $http.post(nowServer.getURL('SignatureANGProcessor', dataURL), payload);
    };
