Flash Builder (FlexPrintJob & PrintDataGrid) Chrome Shockwave error

Question

I have an mx:application using the Flex 4.6.0 SDK and I’m having some issues with the FlexPrintJob in Chrome only. The FlexPrintJob worked fine in chrome, up until maybe a couple weeks ago (I made no changes to the code) and now I’ve started experiencing “Shockwave Crashes”.

While printing I’m using:

first title page template
middle section template to handle a DataGrid. This is using the PrintDataGrid and loops through the dataProvider to see if the data will fit on one page, if not it will create another.
Terms and conditions last page template

Problem: I’ve narrowed it down to this, I’m getting the Shockwave Crash error in chrome when the data (for the middle section) exceeds one page and tries to create another. This just started happening, I’m guessing with a chrome update…Sorry if I left something out and my description is lacking detail. I can add more clarification if needed.

Any ideas what’s going on?

Thanks!

                    break;
                } else // This is not the last page. Queue a middle page. 
                {
                    thePrintView.showPage("middle");
                    printJob.addObject(thePrintView);
                    thePrintView.pageNumber++;

                }
            }
        }
        // All pages are queued; remove the FormPrintView control to free memory.
        removeElement(thePrintView);
    }
    // Send the job to the printer.
    printJob.send();

I ended up taking things apart one-by-one and figured out what it was - the issue was is the FormPrintView. I had some unneeded properties in my PrintDataGrid that I think were originally copied from my main datagrid in my application.

I'm not sure why it was working before and just starting acting crashing now, but either way I shouldn't have had some of those properties there in the first place.

thanks!
