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.
