> Step 1. Add filterMethod method in bean:
> public boolean filterMethod(Object obj) {
> 		Data d = (Data)obj;
> 		if(d.getStr0().startsWith(filterInput)) return true;
> 		return false;
> 	}
> Step 2. Add filterMethod method for rich:column through the "filterMethod" attribute:
> <rich:column sortBy="#{data.str0}"
> 			sortOrder="#{sortingAndFiltering.sortOrder}" filterBy="#{data.str0}" filterMethod="#{sortingAndFiltering.filterMethod}">
> 			<f:facet name="header">
> 				<h:outputText value="#3" />
> 			</f:facet>
> 			<h:outputText value="#{data.str0}"></h:outputText>
> 			<f:facet name="footer">
> 				<h:outputText value="#3" />
> 			</f:facet>
> 		</rich:column>
> Step 3. Add input field for "filterInput" value(See Step 1).
> Step 4. Navigate to the page, contained rich:column described in Step 2.
> Actual behavior:
