Raising the OnControlAddIn event is causing the RTC crash

jdown

Dynamics NAV 2009 R2
.Net 3.5 SP1 (via Visual Studio 2008)

In the Microsoft.Dynamics.Framework.UI.Extensibility.dll assembly, there is an event defined in the IEventControlAddInDefinition interface:

public event ControlAddInEventHandler ControlAddIn;

In my .Net control, I am raising the event like so:

ControlAddIn(args.Action, data);

Where args.Action returns an integer from a custom EventArgs class and data is a standard .Net string.

Once this event is raised, it is supposed to call the OnControlAddIn function:

Search Results - OnControlAddIn(Index : Integer;Data : Text[1024])

. This function is found in NAV on the page that is housing my .Net control (this explains the .Net-Nav event interaction: http://msdn.microsoft.com/en-us/library/dd983799.aspx). Unfortunately, when the event is raised, the RTC is crashing before the code actually reaches the function (I put a confirm message in the beginning of the function to be sure it was blowing up before any code in that function was executed). I have also confirmed that it happens directly after the event is raised by using the .Net pdb files and setting a break-point via

System.Diagnostic.Debugger.Break();

so that I could step through the code as it executed.

The error message is as follows:

The server "net.[url=tcp://srs523:7046/DynamicsNAV/Service]tcp://srs523:7046/DynamicsNAV/Service[/url]" is either unavailable or your connection has been lost. Do you want to attempt to reconnect?

---

Yes No

Here is the event log information (which confirms that the crash is happening after the event is raised from .Net, but before the code in the OnControlAddIn function in NAV is executed):

Thanks in advance for any help.

Well I've managed to resolve the issue. I checked the event log on the server side (original post was from the RTC side) and it turns out my dll file was not found (System.IO.FileNotFoundException). I had to copy the missing dll into the service\addins\ folder (well into a subfolder below that, but you get the point).
