Allocation Fails in Api Logic Server - reports missing relationship

[valhuber]

See the Allocation sample.

Throws: Data error Missing relationship from Parent Provider: <Payment> to child Allocation: <class 'database.models.PaymentAllocation'> of class: PaymentAllocation.

Root cause is in LogicRow:

    def link(self, to_parent: 'LogicRow'):
        """
        set self.to_parent (parent_accessor) = to_parent

        Example
            if logic_row.are_attributes_changed([Employee.Salary, Employee.Title]):
                copy_to_logic_row = logic_row.new_logic_row(EmployeeAudit)
                copy_to_logic_row.link(to_parent=logic_row)  # link to parent Employee
                copy_to_logic_row.set_same_named_attributes(logic_row)
                copy_to_logic_row.insert(reason="Manual Copy " + copy_to_logic_row.name)  # triggers rules...

        Args:
            to_parent: mapped class that is parent to this logic_row

        """
        parent_mapper = object_mapper(to_parent.row)
        parents_relationships = parent_mapper.relationships
        parent_role_name = None
        child = self.row
        for each_relationship in parents_relationships:  # eg, Payment has child PaymentAllocation

                each_parent_role_name = each_relationship.back_populates  # eg, PaymentAllocationList

            raise Exception("Missing relationship from Parent Provider: <"  +
                            to_parent.name +
                            "> to child Allocation: " + str(type(child)) + " of class: " + child.__class__.__name__)

isInstance fails due to packed name in SQLAlchemy meta data expecting a nodal name.

Fix: LogicBank==1.4.3

Replacing isInstance fixes this bug.
