Short description of error
If you bake any liquid, after baking FLIP particles will not be visible in the 3D window. The checkmark Liquid is set. For the FLIP particles to appear, you need to click on the Liquid checkmark (the checkmark will not change its state). After these actions, particles will appear.
Exact steps for others to reproduce the error
Reproduced in any scene.
- [x] Liquid
appears as checked- [x] Liquid
manually doesn't go to an "off" state but stays on a "on" state; it also triggers the creation of a particle systemAdded subscriber: @Pavel_Blend

I can't reproduce this. Baking domain works as intented and shows particles. Could you share a .blend file that is not working for you?
This error occurs in this scene:
mantaflow_bug_01.zip
Perhaps the problem is again in my old video card.
Changed status from 'Needs User Info' to: 'Needs Developer To Reproduce'
Allright this happens for me as well for this file. Unchecking and checking Liquid checkbox make the particles data appear. Let's wait for a developer to reproduce the issue.

The problem boils down to the fact that, when an oject is assigned Domain Type = Fluid, the "Liquid" checkbox appears selected even if it's not.
A minimal way of reproducing the core error is:
- [x] Liquid
appears as checked- [x] Liquid
manually doesn't go to an "off" state but stays on a "on" state; it also triggers the creation of a particle systemThank you @NicolaSap, I will update the description.
Changed status from 'Needs Developer To Reproduce' to: 'Confirmed'
Unfortunately I'm not able to fix this myself, like I wanted to.
If it helps, it looks like adding something like
to rna prop:
"domain_type"
would likely fix this (except this is not the right way, and for example it would break Quick Liquid, which instead works correctly right now because it calls for the update directly from Python).I'd like to point out that this bug has a potentially very high impact on usability!
I'm worried that those who are testing 2.82 are not taking advantage of the FLIP particle visualization at all, because it doesn't work out of the box!

I just incorporated the suggestions from the discussion. I hope this fixes the issue.
I've tried it and it seems to work well (both manual and Quick liquid)!
Not sure who should do this, but this must be ported to the 2.82 branch too
(Thanks!)
@NicolaSap Yes, I accidentally committed this to master first instead of the 2.82 branch. Should be fixed now.
