check if Family table exist

Hey

I have a code to check if there is a family table in the part.

This will in Creo 5 return the name of the instance if it ends with "flat" or "flat1"

But in Creo 11 I get a fatal error.

I thing it is because I don't have a Family table in the part.

How can I check of the part have a Family table?

FamilyMember familyMember = (Solid) model;
FamilyTableRows familyTableRows = familyMember.ListRows();
// Find if a flat version existtube

for (int i = 0; i < familyTableRows.getarraysize(); i++) {
FamilyTableRow familyTableRow = familyTableRows.get(i);
if (familyTableRow.GetInstanceName().contains("FLAT1")) flat_name = familyTableRow.GetInstanceName();
else if (familyTableRow.GetInstanceName().contains("FLAT")) flat_name = familyTableRow.GetInstanceName();
if (!"".equals(flat_name)) break;
}
