For a relativistic system of two scalar particles, we find the Bethe-Salpeteramplitude in Minkowski space and use it to compute the electromagnetic formfactor. The comparison with Euclidean space calculation shows that the Wickrotation in the form factor integral induces errors which increase with themomentum transfer Q^2. At JLab domain (Q^2=10 GeV^2/c^2), they are about 30%.Static approximation results in an additional and more significant error. Onthe contrary, the form factor calculated in light-front dynamics is almostindistinguishable from the Minkowski space one.
