fieldValue

Purpose

Inspects a bean which has been the subject of data binding and obtains the value of the field. If the bean had errors during data binding then the originally submitted value is returned from the bean’s errors object else the value from the bean’s property is returned. The value returned will be HTML-encoded.

Examples

<g:fieldValue bean="${book}" field="title" />

// or as a method
<input type="text" value="${fieldValue(bean: book, field: 'title')}" />
