How can I set component / tag id inside user interface: repeat

I am trying to assign idfor a component inside <ui:repeat>as follows:

<ui:repeat value="#{bean.columns}" var="column">
    <h:panelGroup layout="block" id="column_#{column.id}" 
        styleClass="#{column.id} dashboard_column">

The fact is that the value is #{column.id}correctly placed inside the value styleClassbut is not set inside the attribute id. All that is set inside the attribute idis idmy hard-coded value automatically generated using JSF + column_.

If I am column_hard-coded column_I get an exception:

java.lang.IllegalArgumentException: component identifier should not be a zero-length string in

Any ideas?
