Filter Facet is not working in Richface 4.3x

Question

In the Code below, You can observe two things: 1) Default sorting is getting utilized. 2) Image based custom filter is used.

Problem I am facing : When I click on filter image default sorting is getting triggered. Need a way by which If I click on filter, default sorting doesn't get triggered. (This was achieved in Richface 3.3 by putting this custom filter in filter facet.)

Any help or hint would be greatly appreciated.

    <rich:column sortBy="#{model.modVal}" label="Model Value"
    sortable="true" id="modelVal"  rendered="#{backingBean.renderMap['modVal']}">  
    <f:facet name="header">
    <h:outputText value="Model Value" />
        <h:graphicImage title="Filter"
            value="#{backingBean.dataModel.modValFilter }">
            <a4j:ajax event="click" render="filterCol"
        execute="@form"
        listener="#{backingBean.loadModalPanelData('modVal') }"
        oncomplete="#{rich:component('filterCol')}.show()">
        </a4j:ajax>
        </h:graphicImage>
        </f:facet>
<h:outputText value="#{model.modeVal}"
title="#{model.modelVal}" />
</rich:column>

Answer 1

Use manual sorting, and place a click-able panel in your header for sorting, and another panel for filtering.
