Hi Tim,



The link to valid aircraft type designators on the flight plan dialog no longer works - it should now be http://www.icao.int/publications/DOC8643/Pages/Doc8643.aspx

Using Plan: Deleting the last leg of a route sometimes generates a null reference exception as below.





See the end of this message for details on invoking

just-in-time (JIT) debugging instead of this dialog box.

Thanks, we've updated our link to ICAO.

The other issue you raise is very interesting, I've tried but haven't managed to reproduce it. Is there a specific set of steps that if I follow it enough, will show the fault?

Hi Tim,



Load the attached route (rename .txt to .flightplan)



Then click on the final leg of the route (eden project to newquay) to highlight it and press the 'del' key to remove the leg. Sometimes if this does not fail then right click on newquay and append it back to the route and delete the last leg again as described above this will always cause the exception within two or three attempts.



I've also added the aircraft file in case this is relevent.



Version 2.2.1.28502

Good Morning, I just tried putting in any old route e.g. Sleap to Hawarden to Tatenhill and then deleted the last leg by highlighting and then pressing the delete key. ( I don't normally delete the legs in this way, I normally right click and do it that way) If you delete it by right clicking then there doesn't seem to be a problem. This is what I got 

 " Unhandled exception has occurred in your application. If you click on Continue the application will ignore the error and attempt to continue. If you click on quit the application will close immediately. Object reference not set to an instance of an object"

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

 

It doesn't even have to be the last leg of a route, I have found that I can reproduce the exception by deleting an intermediate leg using the click to highlight leg then 'del' key to delete leg.
