rich:dndParam and s:graphicImage

[x-files]

Indicator displays properly image only first time.

<rich:dragIndicator id="indicator">
 <f:facet name="single">
 {dragImage}
 </f:facet>
</rich:dragIndicator>

<a:outputPanel layout="block">
 <rich:dragSupport dragIndicator="indicator" dragType="pic"
 dragValue="#{file}" >
 <rich:dndParam name="dragImage" >
 <s:graphicImage value="#{imageUtils.scaleImage(file.data)}"/>
 </rich:dndParam>
 </rich:dragSupport>
 <s:graphicImage id="img" value="#{imageUtils.scaleImage(file.data)}"/>
</a:outputPanel>

If uses h:graphicImage instead of s:graphicImage example works fine.

<rich:dndParam name="dragImage" >
 <h:graphicImage value="/some_img.gif"/>
</rich:dndParam>
