M.M.M.E.Elementary.LineForceWithTwoMasses fails to compile

Gets usub_real_array, but the expression is scalar (something wrong with simplify, scalarization or when transforming this to a residual exp)
{{{ usub_real_array(&DIVISION((($PjointUPS$PaxisCylinder$Psize$lB1$rB * xloc[28]) - ($P$DER$PjointUPS$PaxisCylinder$Psize$lB1$rB * $Pbody2$Pv_0$lB2$rB)),

use type of expression for mul when calculate the derivative of DIV_ARRAY_SCALAR
thanks to the new debugger :)
