Hi Hani,

i think this is a performance issue but i found a solution:

<tc:column id=3D"barChart" sortable=3D"false" align=3D"left">
  <tc:panel>
    <f:facet name =3D"layout">
      <tc:flowLayout />
    </f:facet>
    <tc:image value=3D"#{item.gauge.resourcePath}"
                    width=3D"#{item.gauge.width}"
                   height=3D"16" />
  <tc:panel>
</tc:column>

this works in the demo.

Regards,
  Volker
