* <p>Basic text field. Can be used as a direct replacement for traditional text inputs,
* or as the base class for more sophisticated input controls (like {@link Ext.form.TextArea}
* and {@link Ext.form.ComboBox}).</p>
* <p><b><u>Validation</u></b></p>
- * <p>Field validation is processed in a particular order. If validation fails at any particular
- * step the validation routine halts.</p>
+ * <p>The validation procedure is described in the documentation for {@link #validateValue}.</p>
+ * <p><b><u>Alter Validation Behavior</u></b></p>
+ * <p>Validation behavior for each field can be configured:</p>
* <div class="mdetail-params"><ul>
- * <li><b>1. Field specific validator</b>
- * <div class="sub-desc">
- * <p>If a field is configured with a <code>{@link Ext.form.TextField#validator validator}</code> function,
- * it will be passed the current field value. The <code>{@link Ext.form.TextField#validator validator}</code>
- * function is expected to return boolean <tt>true</tt> if the value is valid or return a string to
- * represent the invalid message if invalid.</p>
- * </div></li>
- * <li><b>2. Built in Validation</b>
- * <div class="sub-desc">
- * <p>Basic validation is affected with the following configuration properties:</p>
- * <pre>
- * <u>Validation</u> <u>Invalid Message</u>
- * <code>{@link Ext.form.TextField#allowBlank allowBlank} {@link Ext.form.TextField#emptyText emptyText}</code>
- * <code>{@link Ext.form.TextField#minLength minLength} {@link Ext.form.TextField#minLengthText minLengthText}</code>
- * <code>{@link Ext.form.TextField#maxLength maxLength} {@link Ext.form.TextField#maxLengthText maxLengthText}</code>
- * </pre>
- * </div></li>
- * <li><b>3. Preconfigured Validation Types (VTypes)</b>
- * <div class="sub-desc">
- * <p>Using VTypes offers a convenient way to reuse validation. If a field is configured with a
- * <code>{@link Ext.form.TextField#vtype vtype}</code>, the corresponding {@link Ext.form.VTypes VTypes}
- * validation function will be used for validation. If invalid, either the field's
- * <code>{@link Ext.form.TextField#vtypeText vtypeText}</code> or the VTypes vtype Text property will be
- * used for the invalid message. Keystrokes on the field will be filtered according to the VTypes
- * vtype Mask property.</p>
- * </div></li>
- * <li><b>4. Field specific regex test</b>
- * <div class="sub-desc">
- * <p>Each field may also specify a <code>{@link Ext.form.TextField#regex regex}</code> test.
- * The invalid message for this test is configured with
- * <code>{@link Ext.form.TextField#regexText regexText}</code>.</p>
- * </div></li>
- * <li><b>Alter Validation Behavior</b>
- * <div class="sub-desc">
- * <p>Validation behavior for each field can be configured:</p><ul>
* <li><code>{@link Ext.form.TextField#invalidText invalidText}</code> : the default validation message to

* <li><code>{@link Ext.form.TextField#maskRe maskRe}</code> : filter out keystrokes before any validation occurs</li>
* <li><code>{@link Ext.form.Field#validateOnBlur validateOnBlur}</code>,
