A couple of weeks ago, a new page was created on PartnerSource – the “Demo Microsoft Dynamics NAV” page. You can access it at http://aka.ms/demonav
The page contains (at the time) two scripts and two How Do I videos that help you establish a demo NAV 2015 environment on Azure, in Office 365. The whole process is highly automated and you can get up and running in a matter of minutes. When I say “up an running” I mean this: having a virtual machine running on Azure, with NAV 2015 accessible through Windows, Web, and Tablet client, with single sign-on to Office 365, and a nice demo SharePoint Online portal with several reports from NAV.
If you haven’t yet – give it a try.
Good. At this point we know everything about exception types, what they are, how to obtain them, how to compare them (at least directly). All of these have suddenly become relevant now that we have GETLASTERROROBJECT function in NAV 2015.
But an old friend is still around, the GETLASTERRORCODE function, what about it? Why do we need to bother with GETLASTERROROBJECT when we have a simpler approach, with less peeking into inner exceptions, less reflection, less spooky, obscure .NET internals?

In my last post I have introduced the GETLASTERROROBJECT function that returns you the instance of the System.Exception class, representing the actual exception that has happened.
To properly handle exceptions in an unambiguous way, you must use the exception type, not its name, so it is important to get the actual System.Type representing the exception type.
Sounds easy, but it’s not quite so.

You may love C/AL as a language, but there is an area in it that you must just hate. It’s the error handling. Plainly put, and being actually quite positive about it, in NAV, error handling just sucks. If an error happens, it happens. You have only one possibility to actually capture the error, and it’s the IF CODEUNIT.RUN construct, and it’s limited because you can do it only once per transaction, and if you want to do it twice, you must COMMIT your transaction first.
But still, capturing an error is one thing; actually handling it is quite a different thing altogether.

Most of What’s New information about NAV 2015 will mostly talk about the Word report layouts, as well as the C/AL support for these. However, most of the What’s New documentation doesn’t have a single word about what I find among the most exciting new reporting features in C/AL: the capability to programmatically control the request pages.
