getMemberValueByMemberName gives cast exception if the value is a BigDecimal object

[cedricblom]

Using getMemberValueByMemberName on a member of type BigDecimal results in a ClassCastException since commit 82e06f7.

Potential solution

Replace code on line 33 return MxObject.getValue(getContext(), AttributeName);, with its predecessor:

Object memberValue = MxObject.getValue(getContext(), AttributeName);
if (memberValue != null) {
	return memberValue.toString();
}
return null;
