Signature Action Item not adding signature to SC_TASK item via Agent Mobile.

[Daniel Klaas]

Hi, 

I'm trying to add collect signature functionality to sc_tasks in Agent Mobile. I've created a function and added it the UI of Agent mobile named Signature (see images). When clicked a signature box opens up and allows end users to sign and submit the signature. 

What I want to happen is for the signature to be added to the sc_task record it was generated from. The signature does get collected and added to the signature_image table but nothing else happens. 

This is my execution script on the action item: 

(function WriteBackAction(parm_input, parm_variable, actionResult) {
    var gr = new GlideRecord("sc_task");
    gr.get(parm_variable['sys_id']);
    
    
      // in this example "signatureInput" is the name of a sys_sg_input of type signature
      // SignatureType will return either "Image" or "Text"
    var signatureType = parm_input['Signature']["SignatureType"];
      // SignatureValue will return a String containing the base64 respresentation of the image in the case of a drawn signature
      // or a String with the name of the user if they typed their name
    var signatureValue = parm_input['Signature']["SignatureValue"];
    var table = "sc_task";
    var documentId = parm_variable['sys_id'];
    var signatureHandler = new sn_mobile.MobileSignatureHandler();
    if (signatureType == "Image")
        signatureHandler.insertSignatureImage(table, documentId, signatureValue);
    else if (signatureType == "Text")
        signatureHandler.insertTypedSignature(table, documentId, signatureValue);

gr.update();
})(parm_input, parm_variable, actionResult);

What am I missing here?

Hi Daniel,

The attachment with the signature image is created and stored in the signature images table [signature_image].
This table tracks the table of the record for which signature (sc_task in your case) is needed, the document id of the record, and the signature attachment.

Best regards,
