Data binding using a function reference on page does not work



In Pega 7.4 Mashup, data binding using a function reference on the page does not work. The function defined in data-pega-event-onpagedata attribute is not called and the value 'true' is always returned.

Error Messages

Not Applicable.

Steps to Reproduce

Use the following simple data binding example:

function dataFromPage(key){
if (key=="dataBindTest"){
return "working";

Use the below Mashup attributes to test with:
  • data-pega-action-param-parameters="{testDataBind:'[page/function/dataBindTest]'}"
  • data-pega-event-onpagedata="dataFromPage"

At runtime, the testDataBind parameter always has a value of 'true'.

Root Cause

There was a code issue in PegaCompositeGadgetMgr.js in the _executeFunction method.


Apply HFix-47036.
