Richfaces extendedDataTable frozen column not working when has multiple component in same page.

[java_x_man]

Hi All, 

I'm have an application. It have multiple extendedDataTable like this. 

#Fisrt extendedDataTable

<rich:extendedDataTable id="tbGrid1" 
    value="#{bean data}" var="bean"
    frozenColumns="2" rows="5"
    selectionMode="none">

    <rich:column width="140px">
        <f:facet name="header">
            <h:outputText value="Column1" />
        </f:facet>
        <h:outputText value="Column 1 value"/>
    </rich:column>
    .
    .
    <rich:column width="140px">
        <f:facet name="header">
            <h:outputText value="Column N" />
        </f:facet>
        <h:outputText value="Column n value"/>
    </rich:column>
</rich:extendedDataTable>

#Second extendedDataTable

<rich:extendedDataTable id="tbGrid2" 
    value="#{bean data}" var="bean"
    frozenColumns="2" rows="5"
    selectionMode="none">

    <rich:column width="140px">
        <f:facet name="header">
            <h:outputText value="Column1" />
        </f:facet>
        <h:outputText value="Column 1 value"/>
    </rich:column>
    .
    .
    <rich:column width="140px">
        <f:facet name="header">
            <h:outputText value="Column N" />
        </f:facet>
        <h:outputText value="Column n value"/>
    </rich:column>
</rich:extendedDataTable>

When generate html and css.

#Fisrt extendedDataTable

  div.rf-edt-cnt {
        display: block;
    width: 502px;
    }
    .rf-edt-c-j_idt67 {
        width: 50px;
    }
   .rf-edt-td-j_idt67 {
       width: 50px;
   }

#Second extendedDataTable

div.rf-edt-cnt {
        width: 100%;
    }
    .rf-edt-c-j_idt67 {
        width: 50px;
    }
    .rf-edt-td-j_idt67 {
       width: 50px;
    }

I'm not sure but I think the problem is richface generate duplicate "div.rf-edt-cnt" and use this css class in all extendedDataTable.

because when I view css in FireBug the second "div.rf-edt-cnt" is override first "div.rf-edt-cnt".

How to solve this problem ?.

Environment : JSF 2 (Mojarra 2.1.17), Richfaces 4.3.0 final

Remark : When I remove second extendedDataTable form this page fisrt extendedDataTable is working.

Thanks,
