We recently updated to 5.3.11.1116.  In a large report, we have both a page header and a page footer, and each has a normal 
'Page ' + PageNumber + ' of ' + PageCount
setting.  The footer still works fine, but the header throws a null reference exception.

My next step was going to be to reproduce this in code, so I could step through (the 1-line message where the report should be was little help, as it just said some object was not set). Everything I read about how to set page numbers online tells me that I can only do it in footers and headers (which is where I want), and there are a few discussions about the BeginRenderPage event, which I can no longer find.

So, 2 questions:
1) Any idea how PageCount and PageNumber could be unset in a PageHeader section?  This code has not changed since we upgraded from Q1 2010, but now it does not work.
2) What event should I use to use PageCount and PageNumber fields to set my textbox?

Thanks!

Hi Brandon Beam,

This problem has been fixed in the latest internal build, so you can download it from your account and upgrade to resolve the issue. See release notes here. Sorry for the temporary inconvenience.

Generally The PageCount and PageNumber are global objects and you can use them in expressions. Our suggestion is to avoid events and instead set up the page header/footer expressions to the report definition. You may find useful the Report Life Cycle help article.

All the best,
