The Export to PDF and the Export to Excel buttons do not work the second time.

Steps to Reproduce

  1. Configure a button to call an activity that exports a section to PDF
  2. Configure another button to call an activity that exports a section to Excel

An issue in the custom application code or rules. The button freezes after calling the activity once.


Perform the below local-change:

function downloadFile(activityName, className, applicationName, fileName, fileType){
var suURL = SafeURL_createFromURL(pega.u.d.url);
suURL.put("pyActivity", activityName);
suURL.put("pyClassName", className);
suURL.put('ApplicationName', applicationName);
suURL.put('FileName', fileName);
suURL.put('FileType', fileType);

var formEle = document.createElement('form'); = "download_file";
formEle.method = "POST";
formEle.action = suURL.toURL();
if( = "";

2. Configure the run script on download link or button and call this function
