submodule checkout is not working

[jedwards4b]

git checkout https://github.com/ESCOMP/UFSCOMP.git -b ufs-s2s-app
cd UFSCOMP
./manage_externals/checkout_externals

the issue is that git submodule src/model/FV3/ccpp/frameworkdoes not get checked out.   I don't understand why.

I believe that this is because you have another external called FV3 (from the Externals_s2s.cfg externals). That external is being consulted instead of the .gitmodules file.

I tried to add these to Externals_fv3.cfg explicitly

[atm_cubed_sphere]
protocol = git
from_submodule = True
required = True

[ccpp/framework]
protocol = git
from_submodule = True
required = True

[ccpp/physics]
protocol = git
from_submodule = True
required = True

[fv3gfs_interface]
hash = 8b1014a421
protocol = git
repo_url = https://github.com/ESCOMP/fv3gfs_interface.git
local_path = cime
required = True

[externals_description]
schema_version = 1.0.0

and that results in
ERROR:root:Cannot checkout "ccpp/framework" from submodule information
Parent repo, "fv3" does not have submodules

What I do not understand is the error message is happening before FV3 is checked out (which is why there are no submodules).
