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">. 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.
