"And OF COURSE it is, right in your screenshot!!"
What? You told me that the exact words are:
"Show the FSX Fuel and Cargo page" but the truth, which is proved by my image says
"Show FSX "Fuel and cargo dialog" during refueling".
You do see the difference but pretend something else right! I guess you feel embarrassed
And you call THAT a "difference" ?
It's the SAME, what difference does it make how that label is called ? What matters is the option IS there, and what it does. I might used the older name just because I copied it from the GSX manual, but the actual wording have been updated but, it should have been obvious we are discussing about THAT option, regardless how the exact wording is.
"Of course it is." Of course it is!! But in the previous post you speculated perhaps/maybe that was the case and now when I present the facts it turned out as "Of course it is", come on Umberto.
I really don't know what you are trying to say here with that "come on". I couldn't possibly know what exact files QW might have included or not in their product so, at first, I was obviously correct saying they MIGHT have done that IF you saw the GSX fuel page appearing.
Now that YOU confirmed you found a GSX.CFG file with that option enabled, I also correctly said "of course it is", to point out the reason of that behaviour was entirely expected, considering that file exists.
Your suggestion "as it should" is to turn off custom refueling for the 787 by ticking off that in the plane's configuration having GSX do nothing other than to ask the user to use the planes refueling system. That's not a solution, it's an escape Umberto.
It's not an "escape" or a "bug", it's the proper solution that works for every 3rd party airplane that has a way (or different ways ) to load fuel by itself which are not through the default sim Fuel panel.
Now, the manual states on page 18:
"GSX can handle both cases" and it's referring to 3rd party Custom fuel systems 1 With a progressive fueling and 2 With NO progressive refueling. Also in the GSX settings panel this can be combined with enabling the "Always Refuel Progressively".

You are now confusing the progressive/non-progressive refueling ( which are subsets of the "GSX NOT refueling " case ), with the main "GSX is not refueling" option, which makes that option irrelevant if GSX refuels the plane.
The bug that you explain as "the plane's own loader would likely conflict with GSX doing the refueling". or as you put it "WHEN THE AIRPLANE REFUEL ITSELF". But...there is no loading of fuel happening in the 787! You can load the aircraft's fuel by instantly load it in the EFB, nothing else (Already mentioned by "Fragtality"). There is no basis for a conflict other than GSX itself!!
This confirms you confuse the progressive loading of fuel, with the fact the airplane it's refueling itself. At least, we meant two different things.
When I say "The airplane is refueling itself", I mean EVERY possible way of loading fuel in the airplane EXCEPT GSX OR the default Fuel page of the sim.
It doesn't matter if the plane loads progressively, if it has a custom fuel panel, a loader, an FMC option, or you use a 3rd party utility, or you have a "Load instant" option in the airplane.
Those are ALL cases of "the Airplane refueling itself" and that's why it's best to Disable the option to use GSX refueling in all these cases, not because GSX might not able to refuel that airplane ( it might, if it uses standard fuel tanks, but some airplanes don't ), but because it might disrupt other workflows you might prefer to use for that airplane so, GSX would JUST play its animations, not trying to interfere with an refueling external system.
Another very good reason why it's best to Disable GSX refueling with complex 3rd party airplanes is that, when GSX is refueling the airplane, it will follow its own strategy of progressively filling the various fuel tanks so, at the end of the refueling, you might end up with the correct overall total quantity you requested, but the DISTRIBUTION of fuel in all the multiple fuel tanks might not always be the correct one for THAT particular airplane, because of so many issues with W&B we don't even want to enter into, that are very specific to each plane, and that's why it's best to use the airplane own's systems, that are likely tailored for that airplane, and use GSX for the visual effect only.
Below everyone can find my recommendations for QW787 refueling with GSX 2
1 In the plane config
Enable "Fuel and cargo dialog" during refueling"
If the plane has a custom refuel system, the option should be DISABLED, which is how GSX is set to by default, for this airplane, in the configuration WE supply GSX with.
Enable "Always refuel progressively"
This won't make any difference if GSX is refueling the airplane because...GSX is refueling the airplane so, clearly, it's doing it progressively!
Enabling this option is ONLY useful when GSX is NOT refueling either the airplane doesn't have a progressive refueling, so it always refuel instantly, or it has both methods ( progressive or instant ), but you want the GSX truck to stay there AS IF the plane was refueling progressively.
Disable "Detect custom aircraft system refueling"
If you had this enabled, THIS is likely caused all your issues.
This option should only be used in very rare situations, like planes that do refueling AS PART of an overall "turnaround simulation" and what it does, is to automatically call a Fuel truck in case GSX detects the airplane fuel quantity starts to raise, the only reason to exists is in these cases, since it's not very clear exactly WHEN the airplane will start refueling, it would be a problem when combined with the normal workflow of GSX ( when is NOT refueling the airplane!! ) would just ASK you "Please use the airplane fuel system", because that might already happened, since it was part of an automatic timed routine started by the airplane.
