System Information
Operating system: Linux-4.15.0-52-generic-x86_64-with-debian-buster-sid 64 Bits
Graphics card: GeForce GTX 1080 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 410.104

Blender Version
Broken: version: 2.80 (sub 75), branch: master, commit date: 2019-07-29 14:47, hash: f6cb5f5449

Short description of error
The "Fill Caps" option is greyed out under default, normal circumstances. Adding bevel depth and resolution does not make it available. The only thing that currently makes the option available is selecting a bevel curve.

I was initially hesitant to report this as a bug, given that the behavior matches 2.79. However, the lack of ability to easily add end caps has been annoying me for a while. My reasoning for this being a bug is "there should be no technical reason why a normal, beveled curve should not be able to have filled caps, and having filled end caps can be useful"

                this report, in my opinion

Exact steps for others to reproduce the error

Create a curve object
Add a bevel depth to the curve
Notice unfilled caps
Try to select fill caps

A note on implementation
I'm not sure if fixing this will be as simple as making the fill caps checkbox clickable, even if no bevel curve is selected. If not, I can foresee the following possible solutions

If no bevel curve is selected, pass a default circular bevel curve of the given depth/radius into whatever function does the cap filling
Implement a case in the cap filling algorithm to take into account curves without a custom bevel curve

Hi @finnb,
This was intentionally exluded in 3b3d811bf0.
Not saying this isnt possible (I have made quick tests by removing the check for cu->bevobj from here )
But as the commit message from above commit mentioned, this would not work in any case [has problems with beveled+extruded 2D curves at least].
So you are running into situations like these:

That all being said, this is a nice suggestion, but atm. this would be more like a feature request that could go to https://blender.community/c/rightclickselect/ instead...
Will close this as not-a-bug [unless @Sergey has objections and wants to pick this up?]
