&lt;title&gt;Lista De Alunos&lt;/title&gt;
&lt;link href="css/estilo.css" rel="stylesheet" type="text/css"&gt;
&lt;/head&gt;
&lt;body&gt;
	&lt;center&gt;
&lt;f:view&gt;
	&lt;h:outputText styleClass="title" value="Listagem dos alunos" /&gt;<br><br>
	&lt;h:form&gt;
	&lt;rich:dataTable id="alunos" border="1" value="#{alunoBean.lista}" binding="#{alunoBean.objDataTableAluno}" var="a"  rendered="#{not empty alunoBean.lista}" rows="6"&gt;

Ola galera , tem alguem que pode ajudar a solucionar este problema

#5

alguem pode ajudar!!!

#6

qual o tipo do seu objeto [color=red]objDataTableAluno[/color] ??
É um htmlDataTable??

#7

Veja: um UIDATA DO import javax.faces.component.UIData;


UIData controle.AlunoBean.objDataTableAluno
#8

Acredito que o binding deva ser feito com um objeto do tipo HtmlDataTable
