4336	Problem with code generation involving arrays of components containing arrays of Real variables	Francesco Casella	Mahder Alemseged Gebremedhin	"Please consider the model {{{DEMOSimple.Test.Helium.TestCP}}} from the attached package. The model is accepted by the front-end, and it actually simulates successfully in Dymola.

However, when compiling the C code generating by OMC, the following error message pops up:
{{{
DEMOsimple.Test.Helium.TestCP_02nls.c: In function 'residualFunc53':
DEMOsimple.Test.Helium.TestCP_02nls.c:53:3: error: '$OLD_$PheliumCP$PchB$lB2$rB$PTm$lBtmp3$rB' undeclared (first use in this function)
   $OLD_$PheliumCP$PchB$lB2$rB$PTm$lBtmp3$rB = $PheliumCP$PchB$lB2$rB$PTm$lBtmp4$rB;
   ^
}}}
The involved variable is an element of a Real array inside an array of models.

Can you please have a look and fix it?"	defect	accepted	high		Code Generation				antonio.froio@…
