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.
