styleClass attribute on t:column having no effect when columnClasses attribute is present on t:dataTable

[Matt Hughes]

If you have a dataTable as such:

<t:dataTable
   columnClasses="colClassOne, colClassTwo, colClassThree"
   value=".." >
   <t:column styleClass="editMode"></t:column>
   <t:column styleClass="viewMode"><t:column>
</t:dataTable>


The rendered HTML only has the style classes specified in the 
columnClasses attribute.  Is this the desired effect?  I was not able to 
find any documentation specifying what was supposed to happen if you had 
both of them.  I believe that the styleClass attribute on the t:column 
element should be *added* not ignored.  So the resulting HTML *should* 
IMHO look like this.

<table>
   <tr>
   <td class="colClassOne editMode"></td>
   <td class="colClassTwo viewMode"></td>
   <td class="colClassThree"></td>
   </tr>
</table>

Instead of:

<table>
   <tr>
   <td class="colClassOne"></td>
   <td class="colClassTwo"></td>
   <td class="colClassThree"></td>
   </tr>
</table>
