public class InputTextAreaTag

Tag that generates HTML form fields of type <textarea name="foo"> ... </textarea>, which can dynamically re-populate their value. Textareas may have only a single value, whose default may be set using either the body of the textarea, or using the value="" attribute of the tag. At runtime the contents of the textarea are determined by looking for the first non-null value in the following list:

A value with the same name in the HttpServletRequest A value on the ActionBean if an ActionBean instance is present The contents of the body of the textarea The value attribute of the tag
