The defaultValue attribute takes either a String literal or a data binding expression.

If the defaultValue attribute has a String value (or if the data binding expression points to a String), then a single value will be preselected.

If the defaultValue attribute points to a String[] object (or any object which can be iterated over), then multiple values will be preselected.

Use in <netui:textArea> and <netui:textBox> tags

Sets the initial display text.

The defaultValue attribute takes either a String literal or a data binding expression that points to a String.
