# Class Error

java.lang.Object
org.apache.tapestry5.corelib.components.Error

@SupportsInformalParameters public class Error extends Object
Provides a client-side element to contain validation errors; this renders as a `<p class="help-block">`. Must be enclosed by a `Form` component and assumes the field and the Error component are enclosed by a `<div class="[form group CSS class]">`, where `[form group CSS class]` is defined by the value of the `SymbolConstants.FORM_GROUP_WRAPPER_CSS_CLASS` configuration symbol (`tapestry.form-group-wrapper-css-class`). It is acceptable to include multiple Errors components for a single field; this is sometimes necessary when creating a responsive layout - which should probably ensure that only one of the Errors is visible at any time. Errors is optional, and Tapestry's client-side logic will do a reasonable job of placing a help block dynamically when a validation error must be presented; this component is intended for use when the default logic doesn't place the help block in the right spot.

Since:
  5.2.0
