Hello,

I’m trying to update some code from version 0.6 to 0.7.2. I’ve implemented the obvious changes between the versions, but ffcx still refuses to compile the form. The error is when I sum an integration over the domain and the facets. The 2 parts of the form compile correctly when taken in isolation.

here is the code stripped of all the unnecessary :

```
import basix
from ufl import (Mesh,
Coefficient,TestFunction,FunctionSpace,FacetNormal,
TrialFunction,Constant,Measure,dx,ds,dS,
dot,grad,derivative,variable,Identity,tr,det,
SpatialCoordinate,as_matrix,as_vector,as_tensor,inner,inv,sqrt,cross, action,sym)
from basix.ufl import element, quadrature_element
cell = "hexahedron"
# Coordinate Element for Mesh
elementV = element("Lagrange", cell, 1, shape=(3,))
mesh = Mesh(elementV)
normal = FacetNormal(mesh)
# Lagrangian spaces
V = FunctionSpace(mesh, elementV)
# Quadrature space for stress
VQV_ele = quadrature_element(cell, degree=2, scheme="default", value_shape=(6,))
VQV = FunctionSpace(mesh, VQV_ele)
# Get points and weights for custom integration measure
points, weights = basix.make_quadrature( basix.cell.string_to_type(cell), 2, basix.quadrature.string_to_type("default"))
metadata = {"quadrature_rule": "custom", "quadrature_points": points, "quadrature_weights": weights}
dx = Measure("dx", domain=mesh, metadata=metadata)
# Define Functions for linear problem
v = TestFunction(V)
# Define quadrature functions for the weak form
q_sigma = Coefficient(VQV)
# strain measure function (used for strain increment in weak form)
def eps(v):
e = sym(grad(v))
return as_vector([e[0, 0], e[1, 1], e[2, 2], 2 * e[1, 2], 2 * e[0, 2], 2 * e[0, 1]] )
# Load application on single facet
Pmax = Constant(mesh) #Max load
# Variational Form
L_form = -inner(eps(v), q_sigma) * dx + Pmax * dot(normal, v) * ds
forms = [L_form]
```

here is the error:

```

can anybody help?

I’m using the latest stable version [dolfinx 0.7.2; ffcx 0.7.0]
