<h3>Grid BeanModel (1)</h3>
We can take more control of the Grid when we provide the BeanModel ourselves. It is a model that defines how
data will be mapped into the grid. It does not contain the data.
<div class="eg">
<t:grid source="persons" row="person" model="mymodel" rowsPerPage="4" pagerPosition="top">
<p:actionCell>
<t:pagelink page="examples/tables/GridBeanModel2" context="person.firstName">View</t:pagelink>
</p:actionCell>
</t:grid>
</div>
To see manipulation of the BeanModel by a mixin, go to the Creating Mixins example.<br/><br/>
