Hi!

I need to use a4j:mediaOutput component with an area map.

The map should be updated every time the image is generated.

The problem is the map is rendred _before_ the actual image is rendered and loaded.

So I need some callback to refresh my map after the image is loaded. Please suggest a proper way to to this.

<a4j:mediaOutput usemap="#myMap" element="img"

                         cacheable="false" session="false"

                         createContent="#{imageMapBean.paint}"

                         value="#{graph.connections}"

                         mimeType="image/jpeg">

</a4j:mediaOutput>

<a4j:outputPanel id="mapGroup">

        <map name="myMap">

            <a4j:repeat value="#{imageMapBean.imageMapAreaList}" var="area">

                <area shape="rect"

                      coords="#{area.bounds.x}, #{area.bounds.y},#{area.getRightX()},#{area.getBottomY()}"

                      onclick="openLink('#{area.blockId}');return false;" href="#"/>

            </a4j:repeat>

        </map>

</a4j:outputPanel>
