## Class Errors

- java.lang.Object
- - org.apache.tapestry5.corelib.components.Errors

-     public class Errors
      extends Object

  Standard validation error presenter. Must be enclosed by a `Form` component. If errors are present, renders a `<div>` element around a banner message and around an unnumbered list of error messages. Renders nothing if the `ValidationTracker` shows no errors.

  Component Parameters
  Name | Type | Flags | Default | Default Prefix
  --- | --- | --- | --- | ---
  banner | String |  | message:core-default-error-banner | prop
  The banner message displayed above the errors. The default value is "You must correct the following errors before you may continue.".
  class | String |  | symbol:tapestry.errors-default-class-parameter-value | literal
  The CSS class for the div element rendered by the component.
  globalOnly | boolean | Since 5.4 |  | prop
  If true, then only errors global to the form (unassociated with any specific field) are presented. By default all errors (associated with fields, or not) are presented; with unassociated errors presented first.

  ### Examples

    The Errors component automatically connects with the Form that encloses it. Just place the component inside a Form.

    ### Search.tml

        <html xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd">
            <body>

            <t:form>

                <t:errors/>

                <t:label for="search"/>
                <t:textfield t:id="search"/>

                <input type="submit" value="Search"/>

            </t:form>

            </body>
        </html>

    The Errors component here will display any validation errors that occur when the form is submitted.
