When you provide an array of objects, we attempt to create an
ObjectArrayDataProvider for you. (Note that you can provide this
yourself via the same value expression. There are several types of
providers available, but they all deal with Object.) This Object must
contain a getter and setter for each value to be displayed. (The Object
typically contains multiple values for a given row.) You can create an
Object that get/sets String values, but you cannot provide individual
strings directly as the sourceData property.
