Root Cause

The documentation here https://pdn.pega.com/pega-web-mashup-page-javascript-actions/pega-web-mashup-page-javascript-actions  is out dated.

The API for getGadgetData, setGadgetData and getGadgetInfo has changed as of Pega 7.2.1 and the documentation changes are not yet complete on PDN.
 

Resolution

Similar to https://pdn.pega.com/support-articles/getgadgetdata-always-returns-undefined-when-using-mashup
 

Pega now uses Window post messages for communication from top level application to PRPC. The nature of this change requires callback functions.

pega.web.api.doAction("GADGETNAME", "getGadgetData", "[pyWorkpage.Property]", {callback:function(){},scope:scope});

pega.web.api.doAction("GADGETNAME", "setGadgetData", "[pyWorkpage.Property]", "value",{callback:function(){},scope:scope});

pega.web.api.doAction("GADGETNAME", "getGadgetInfo", {callback:function(){},scope:scope});

Example: getGadgetData:

function getTheGadgetData(){

    pega.web.api.doAction("GCSTestDataBind", "getGadgetData", "OperatorID.pyFirstName", {callback:callBackForFirstname});

}

function callBackForFirstname(rtnValue)

{

  alert("return value: " + rtnValue);

}

DataField not used anymore:
 

Also as of  Pega 7.2.1 DataField controls are no longer used for getGadgetData. Instead use a simple hidden input element using the control "Hidden Input".

Application Integration and Security:

On the application record there is an Integration and Security tab that contains a “Mashup Security” section. This must contains the host site that is including the Mashup content.
