Download working only once
I want to download a simple text document on click of a button in PRPC7.3.1. On click of the button I refreshed the section and called an activity that has just one java step. The java content is given below. On first click of the button, the document is downloading properly but thereafter its not throwing to browser. I traced, all the steps are executing properly. If I refresh the complete URL from browser, it again works fine for one time only.
ClipboardPage objHeadersPage = tools.findPage("pxRequestor").getProperty(".pyHTTPResponseHeaders").getPageValue();
objHeadersPage.putString("contentType" ,"text/plain");
objHeadersPage.putString("ContentDisposition" ,"attachment;filename=test.txt");
String contents="Hello World!!";
byte[] bContents=contents.getBytes();
String result=tools.sendFile(bContents,"test1.bat", false, null, true);

Seems similar to the issue in the below Support Article. It may need to be modified depending on your scenario but worth checking.

Hi Abikash,
What do we need to pass as applicationName? and the activity (which i guess is our custom activity), does it also contain the exporttoexcel step also?

Hi Avishek - You can get Application Name from your access group. The activity should contain a step that throws the excel's content byte array to browser e.g tools.sendFile(byteArray,FileName, false, null, true);

Thanks Abikash. So, will it work if I directly call ExportToExcel in the custom activity? Because if the activity is run stand alone it generates the excel and downloads it.

Easiest solution for me was to trigger the button to "open url in window" then call an activity with your code attached. Window pops up for a split second and download triggers every time.

Hi
I am also facing the same issue.
I have a grid and each record in the table has a link. Onclick of link, the file download needs to happen from a specific location. I am using activity to download the file. I am able to download one file only. If I try to download the next.... nothing happens on click.
The link "https://pdn.pega.com/support-articles/export-excel-downloads-file-only-once" is not working anymore.
