> Since Richfaces Version 3.3.1.GA an exception is thrown, when value of rich:columns is null. 
> For example:
> <rich:columns value="#{someList[0].years}" var="year" index="index" rendered="#{not empty someList[0].years}">...</rich:columns>
> throws: 
> javax.servlet.jsp.JspTagException: FOREACH_BAD_ITEMS

> 	at org.richfaces.iterator.SimpleForEachIterator.supportedTypeForEachIterator(SimpleForEachIterator.java:98)
> 	at org.richfaces.taglib.ColumnsHandler.prepare(ColumnsHandler.java:304)

> 	at com.sun.facelets.tag.CompositeFaceletHandler.apply(CompositeFaceletHandler.java:47)
>         ....
> because supportedTypeForEachIterator(Object o) in SimpleForEachIterator is called with null.
