[CA] [CA11] GPX File Write or Other Format Error?

[Dan_Y]

Hello –
I backed up a GPX file prior to upgrading our Axiom 9 from LH3.7 to LH3.9. The GPX file contains 4 way points followed by two tracks (Track 3 and Track 7) from two short, season opener sails. I use “GPX Viewer and Recorder” to look at GPX files.

In this file, GPX viewer and reader renders the four waypoints , but will not render the two tracks. GPX Viewer and Recorder provides a summary of the track info and shows no data in Track 3 and data in Track 7. Track 3 data is located just after the four waypoints in the file, followed by track 7.

Opening the GPX file shows Track 3 info is in the file. After deleting Track 3 information from the GPX file, the four waypoints and Track 7 render correctly. So, GPX Reader and Viewer displays the waypoints then chokes on Track 3 and then looses it's mind and can't display Track 7.

I realize this GPX file was written by LH3.7 and I have not recorded a track with LH3.9 to confirm GPX file functionality. I thought this was an interesting finding in case there is a latent error in how GPX files are written. I’m not familiar enough with the GPX file format to troubleshoot. The JSON file (unfortunately after the upgrade to LH3.9) is included for MFD/Network info.
