Accept Attribute on rich:column

[koallen]

The  showcase example for rich:dataScroller inlcudes the attribute "accept" in the provided rich:dataTable, but the acceptVendor method does not exist in the source code for the filtering bean carsFilterinbean, does anyone know how this attribute is used ?

<rich:dataTable value="#{carsBean.allInventoryItems}" var="car" id="table" rows="10">

                <rich:column accept="#{carsFiteringBean.acceptVendor}">

                    <f:facet name="header">

                        <h:outputText value="Vendor " />

                    </f:facet>

                    <h:outputText value="#{car.vendor}" />

                </rich:column>

                <rich:column>

                    <f:facet name="header">

                        <h:outputText value="Model" />

                    </f:facet>

                    <h:outputText value="#{car.model}" />

                </rich:column>

                <rich:column>

                    <f:facet name="header">

                        <h:outputText value="Price" />

                    </f:facet>

                    <h:outputText value="#{car.price}" />

                </rich:column>

                <rich:column>

                    <f:facet name="header">

                        <h:outputText value="Mileage" />

                    </f:facet>

                    <h:outputText value="#{car.mileage}" />

                </rich:column>

                <rich:column>

                    <f:facet name="header">

                        <h:outputText value="VIN " />

                    </f:facet>

                    <h:outputText value="#{car.vin}" />

                </rich:column>

            </rich:dataTable>

            <rich:dataScroller for="table" maxPages="5" />

I cannot find the attribute / property "accept" anywhere in the rich:column sources for richfaces 4.1.0.FINAL

Only:

        breakRowBefore,

        colspan,

        comparator,

        filter,

        filterExpression,

        filterValue,

        footerClass,

        headerClass,

        rowspan,

        sortBy,

        sortOrder,

        style,

        styleClass,

        width

I could not find it either when I checked the source code, so that begs the question why it is in the showcase.
