StaticOrderPrintJob null exception on isReprint

Hi Clover Dev,

I'm having a hard time trying to get the StaticOrderPrintJob to print an orders line items

#1:

StaticOrderPrintJob.Builder().order(order).build().print(Activity.this, account);

#2

I'm atleast able to get it to print dates, times, and the order number when I include a string array in .itemIds(stringArray) e.g:

StaticOrderPrintJob.Builder().markPrinted(true).reprintAllowed(true).itemIds(itemIds).order(order).build().print(Activity.this, account);

But none of the line items print in that case.. I'm just getting the dates and order id.

Below is the log output when it crashes with attempt #1. I'd love to take a look at that com.clover.engine.printer.PrintService class to see what i'm missing. Is there any documentation on what's required? Is it something missing from my order object by any chance? Thanks

To answer my own question:

I set in my order object with:

lineItem.setPrinted(false);

How did you create the order and line items?

I'm building them from my own data. I got to a point where I could print the full order only if none of the items had modifications. I'm obviously not creating the modifications properly as its hitting a similar NullException in a class I have no access to. I've given up on StaticOrderPrintJob. I have the ViewJobPrint working now, I just need to make it bigger and pretty! Thanks for looking Jeff

We expect that people use the methods in OrderConnector to create and build the order. Unfortunately there are a few assumptions the receipt code makes w/ regard to the structure of the order as it would be built from that. That being said, it's a bug that it crashes in that case. It is just poor coding on our part that we didn't perform a null check on the printed flag.

If you want to use StaticOrderPrintJob with your own hand-built Order object, I'd suggest you look at the JSON for an order created by the Clover Register app and try to mimic all of the fields therein. ViewPrintJob is fine too of course.

I appreciate it Jeff, I've since found ViewPrintJob to work quite well for what I need. Thanks for the help!
