Steps to Reproduce
- Create a section with multiple links.
- Add an action or event combo for the links: onClick, Section Refresh, and activity pyDownloadBinaryFile.
- Click a link to a download file.
- Click another link to download a different file.
Root Cause
The section refreshes on the click of the link and this causes the issue.
Resolution
Perform the following local-change:
1. Copy the following JavaScript function in the UserWorkForm.
<script>
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');
formEle.id = "download_file";
formEle.method = "POST";
formEle.action = suURL.toURL();
if(pega.env.ua.webkit)
formEle.target = "";
document.body.appendChild(formEle);
formEle.submit();
document.body.removeChild(formEle);
}
</script>
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');
formEle.id = "download_file";
formEle.method = "POST";
formEle.action = suURL.toURL();
if(pega.env.ua.webkit)
formEle.target = "";
document.body.appendChild(formEle);
