ColumnClasses styles is ignored

I am using <t:dataTable> and I am using the attribute columnClasses. According to (http://myfaces.apache.org/tomahawk/tlddoc/t/dataTable.html) columnClasses - A comma separated list of CSS class names to apply to td elements in each column.

But this does not happen, when I define the columnClasses styles to be applied in each column only the very first class is rendered for all columns.

This is how I did it:
<t:dataTable id="myDetailDataTable" var="row" value="#

{myDetailList.rows}

" cellspacing="0" columnClasses="columnClassLock,columnClassUnlock" headerClass="headerClassTopLock" rowClasses="rowOdd,rowEven" styleClass="dataTable">
<t:columns value="#

{myDetailList.columns}

" var="currentColumn">
<f:facet name="header">
<h:outputText value="#

{currentColumn.name}

"/>
</f:facet>
<h:outputText value="#

{myDetailList.columnValue[currentColumn.name]} " style="#{myDetailList.columnValue[currentColumn.label]}" rendered="#{not myDetailList.columnValue[currentColumn.render]}" escape="false"/>
<h:inputText value="#{myDetailList.columnValue[currentColumn.name]}

" style="#

{myDetailList.columnValue[currentColumn.label]}

" rendered="#

{myDetailList.columnValue [currentColumn.render]}

" size="6" maxlength="15">
<f:converter converterId="javax.faces.BigDecimal"/>
</h:inputText>
</t:columns>
</t:dataTable>
