Loop through couple of work cases with HTMLToPDF only generate 1 PDF
I'm trying to generate several PDF by manually triggering an activity that will loop through several Work cases by calling the OOTB method HTMLToPDF to generate the PDF. If I run it with only 1 Work case then it will work and I get the file but when I run this activity with multiple Work case then it will only populate the last case and give me only one PDF. How do I loop through HTMLToPDF to give me one PDF for each Work case with one activity call?

Hi,
Can you please elaborate on how you're capturing the PDFs after calling HTMLtoPDF?
Are you attaching them to a work object using an activity such as Code-Pega-PDF.AttachToWork, or are you displaying them directly such as view Code-Pega-PDF.View?
When you loop through the cases, are you displaying or attaching the PDF within the context of the loop as well?

I don't need to attach or view it.
I need the pdf download on my local desktop.
After HTMLToPDF there's a java step that will download the file and open it immediately.
Below is the java step after HTMLToPDF
String PDFFileName = tools.getParamValue("PDFName");
PDFFileName = PDFFileName + " for Audit" +".pdf";
Object pdfBytes=tools.getParameterPage().getParameterValue("PDFDocument");
byte[] byteArray=(byte[])pdfBytes;
String result=tools.sendFile(byteArray,PDFFileName,false,null,true);

Hi Danny,
I tried a sample use case to achieve your requirement and attached the document into the pulse note. You can review it and try at your end, please make sure you follow the same names for the parameters. The tricky part in this use case is the iteration of the work objects and storing the Markup content of the each work object into a local variable before we try to generate the PDFDocument which is used to generate the PDF file by HTMLToPDF java code.
Hope this might help you to achieve your requirement.

Thanks for the quick response!
Your solution will concatenate all the Work cases into 1 PDF.
If there are 3 work cases, I need 3 separate PDFs, is this possible?

Hi,
Using HTMLToPDF will generate the last Work item PDF as stated by Mahesh.
The simplest solution possible is to concatenate all the files in a ZIP File and then download the same.
Use the JAVA code from below link to create a zip file using the generated PDF object.

The ZIP file can then be generated using function sendFile from PublicAPI.
