title: PrimeFaces DataTable with required Radiobutton
body: <p>I am using PrimeFaces DataTable with Radiobuttons inside a one wizard tab. Is possible to somehow set Radiobuttons like <strong>required</strong>?</p>
  
  <p>User shouldn't go to the next wizard tab until he will choose one option in DataTable with Radiobuttons.</p>
  
  <p>Or  have you any ideas how to resolve this problem? Thanks for any replies!</p>

      &lt;p:panel header="Term page"&gt;
          &lt;p:dataTable id="collection" value="#{register.dataList}" var="dl" rowKey="#{dl.c_id}" selection="#{register.selectedTerm}""&gt;
              &lt;p:column selectionMode="single" style="width:2%" /&gt;
              &lt;p:column&gt;
                  #{dl.c_id}
              &lt;/p:column&gt;
          &lt;/p:dataTable&gt;
      &lt;/p:panel&gt;
