PDF Download not working first time
I want to download PDF file with @baseclass pyViewAsPDF Activity.
I attached the setting of Activity(see cap1.JPG, cap2.JPG). I have set Open URL in Window as button click Action(see cap3.JPG).
I expected I can download PDF when I click the button. But after I restarted Pega Application, I downloaded 0 byte PDF file first time and I colud download PDF file second time successfully.
How can I download PDF file first time successfully ?

Thank you for your reply. I hear that this behavior is bug in 3rd party library. And, workaround is below:
- add a refresh harness before the PDF generation
- open UseCompactStylesforPDF DSS setting and mark it as true
- add param.pyClearCache as true without ""

@Tanay Kumar Bal Thank you for your reply.
I tried passing "_self" against the parameter Window name when you are doing Open URL in window. But I downloaded 0 byte PDF file first time.
And, Pega Platform version is 8.6.0.

Can you try passing the parameter SectionName as well. Check the HTML rule you have referred. It is looking for a section as well.
tools.getStepPage().putString("pyTransientText",tools.getParamValue("SectionName"));
Having said that, I tried doing the same and even if I don't pass SectionName, for me it downloads a 19KB file and after I pass the section name it downloads the section as is. Both on first click.
BTW what is the actual need here?

@kobat I tried the above steps, but didn't work for me. A question I have here:
what is the significance of pyclearcache parameter? I could not find it used anywhere.
I am facing issue like, sometimes which i am clicking on generate PDF button, its giving the blank window without downloading the pdf.I guess you also faced the same issue?
