InFlight 

Thank you for the bug report. I can't reproduce this, as, according to the stack trace, it will only happen if it is the first static dialog that is created by the game. Unfortunately, this is also a bug in Blizzard's code, where they aren't abiding by their own new frame restrictions that they introduced in WoW 8.2, as the frame that is causing the error is being created and controlled by their code.

Updating to the latest version of InFlight (v8.2.003) might help.

If that doesn't work for you, then turning off flight confirmation until Blizzard fixes their code may be the only way to avoid this error.

Thank you for the bug report, unfortunately I'm unable to replicate this error.
Is this error repeatable?
Does it occur when InFlight is the only addon loaded?
Are you sure you landed at 'The Argent Stand'? I'm only asking this because that flight point isn't on the flight path from the 'Argent Tournament Grounds' --> 'Westfall Brigade', although it used to be in a previous expansion. If this is the case, then the server hasn't implemented the secure function TaxiRequestEarlyLanding() correctly, as InFlight uses a secure function hook on this API function to know when to not save the flight time when the button is pushed.

I was flying from the Argent Tournament Grounds to Westfall Brigade, but I hit the button to cancel the flight early. I actually landed at The Argent Stand, but the chat message said it updated the original path (Argent Tournament Grounds --> Westfall Brigade) with the time it took. Not sure if it updated the original path or if the message displayed was just incorrect, but figured I'd report it.

In 'Bar Options', untick 'Fill Up'

Is there an option to show how long the flight lasts?

It shows how long the flight takes in total and how long you have been flying, but for me the remaining time would be interesting.

yeah i disabled the chat messages as i found them annoying hehe , glad to hear it will be fixed in new version ^^

Updating to the latest version resets all flight times back to defaults due to the database being completely re-written. As the defaults don't have any 8.2 flight times, then these will have been lost and will need to be re-learned.

Otherwise, I've been unable to reproduce this error. Once I've learned a new flight path, it's known for all of my character's of the same faction, even after re-starting the game.

If this is still happening to you, then can you please upload your flight times to the flight times thread and let me know what faction and what flight point you are starting from to get to Overspark Expedition Camp, so that I can try and track down the cause.
edit: and 'locale', in case it's due to a localisation glitch as they were also completely re-written for this release.
2nd edit: also, if you turn chat messages back on, at the end of the flight that it doesn't know, it should say that it has added the new flight time. Does this happen?

3rd edit: my last edit reminded me that the code for the chat messages at the end of the flight got modified twice, once for the database changes and once for the localistion changes. So I thought I'd better review that code and just make sure it was really doing what it should. Turns out that the logic got a bit messed up, so if you don't have chat messages turned on, then the new time doesn't get saved.
This will be fixed for the next release, thank you for the bug report.

Hello,

the addon does not seem to remember new times, i have flown to Overspark expedition camp in Mechagon from Boralus (same FP always) since day one and still it keeps trying to "calculate" the time from those points lol

not sure if older FP's are also affected since i already had a fair share of times, this one i really noticed

Thank you for the translations, I've been slowly working on overhauling the localisation system to reduce InFlight's footprint and make it easier to maintain flight points across all supported languages.

One of the steps for this is to make it easier for translators by using CurseForge's localisation support. Feel free to have a look and submit any further updates there.

Hi, i have made a new german translation for InFlight. I hope it's useful.
I'm sorry if this is not the right place to post stuff like that.

I can't test all the flights, my chars are in Outland yet.

As far as I can find, your addon is the only one being updated for Flight Master timing, etc.

The other(s) have been removed from Curse. Now sure about wowinterface.

I like this addon.

InFlight doesn't create a list of flight points, it only adds the flight time to the flight point tooltip and adds a flight timer bar while flying from one flight point to another.
If you used to have a list of flight points next to the flight map, that list was most likely generated by an addon similar to Flight Map Enhanced & Times

Addon no longer works at all. I don't get the list of fps just the map. And both components are loaded, in flight and the load module.

I accidentally managed to trigger this bug. The error message saying that you are busy is from WoW and is most likely due to you still being in combat, at least, that is what happened to me. There actually is a vehicle check, unfortunately that was where the bug was. This has been fixed for the v8.0.006 release.
