NAV 2013 'Control Add-in Error' message when opening a page

MuadD1b

Hi all,

I'm getting the enormously vague error 'Control Add-in Error' that contains an add-in that I've just created.
Normally I'd check the public key and DLL's in the add-in folder. But obviously I've already done that. The info is correct and the files are there.

When I attach my Visual Studio debugger to the RTC client process and run the page, I see that the control is being initialized.
The CreateControl and OnInitialize methods are being invoked and don't throw any exceptions. Therefore I conclude it's not an error in my .NET code.

Any ideas? The Windows application event log does not contain any clues.

Regards,
Erik
