<h3>Easy CRUD</h3>
<noscript class="js-recommended">
${message:javascript_recommended}
</noscript>
This example demonstrates how Tapestry can handle CRUD (Create, Review, Update, Delete) with ease.<br/>
It uses the Grid, BeanEditor, and BeanDisplay components which are especially great for prototyping.
<div class="eg">
<t:pagelink page="together/easycrud/person/PersonCreate">Create...</t:pagelink><br/><br/>
<t:if test="errorMessage">
<div class="alert alert-danger">
${errorMessage}
</div>
</t:if>
<t:grid source="persons" row="person" include="id,firstName,lastName,region,startDate" add="action">
<p:actionCell>
<t:pagelink page="together/easycrud/person/PersonReview" context="person.id">Review</t:pagelink>
<t:pagelink page="together/easycrud/person/PersonUpdate" context="person.id">Update</t:pagelink>
<t:eventlink event="Delete" context="[person.id,person.version]"
t:mixins="Confirm" Confirm.message="Delete ${person.firstName} ${person.lastName}?">Delete</t:eventlink>
</p:actionCell>
</t:grid>
</div>
<t:pagelink page="Index">Home</t:pagelink><br/><br/>
