What if the property.someValue does not exist? How do I check if the reference to dataprovider[i].someValue property is null?
my dataprovider is an arraycollection and holds different objects. Some objects have .someValue property and some do not. When i try to step through it it doesn't like it when it expects a property but it is not there.
