RTC Connection stopped working

vaprog

Hello

I have a rather strange issue which I failed to resolve so far.

I have been designing a page part for a role center. In order to test my changes I closed my running windows RTC and tried to restart it, which failed.
Error Message (in German (don't know how to switch the language in this non-functional state:

---

Microsoft Dynamics NAV

---

The server "net.tcp://<host>:7046/<instance>/Service" is either unavailable or your connection has been lost. Do you want to attempt to reconnect?

---

Ja Nein

---

Answering Yes gets me the following message:

---

Microsoft Dynamics NAV

---

The session could not be retrieved from the server. The application will close.

---

OK

On the client, a NavConnectionLostException is logged in the event log.

On the server, event 216 from source MicrosoftDynamicsNavServer$<instance> is logged in the Application log:

Here's what I tried so far:

• I checked all .xml and .config files in the service installation folder, the instance folder, the server's folder tree in %ProgramData%, NAV's folder in the service users and client user's %APPDATA% on the server. On the client I checked the client's config and deleted PersonalizationStore.xml
• The error is not user or client computer specific (i.e. other users get the same error on their own workstation).
• I tried recompiling all objects and syncing the database
• Starting a different profile using the -profile parameter when starting RTC works
• I deleted records in tables "Profile Metadata", "User Personalization", "User Metadata", and "Page Data Personalization"

Does anyone have any suggestion on what else I might try to get my role center working again?

You must have some code in your new pagepart that is causing this. I would remove everything from the pagepart recompile and check that the role center is working again. Then add small chuncks of code and see when it fails.

I found the culprit. It turned out to be the Visible property on one of the fields (a cue) on the CardPart page. I had used a boolean field of a record variable. Everything is all right with a global variable of type boolean instead.

Btw. I was using NAV 2016 CU19

Yes, that's exactly what I did after I wrote this request for help. I trusted the compiler not complaining, paired with the severity of the fault, too much.
