rich:columns throws Exception when value is null
------------------------------------------------

                 Key: RF-7524
                 URL: https://jira.jboss.org/jira/browse/RF-7524
             Project: RichFaces
          Issue Type: Bug
    Affects Versions: 3.3.1
         Environment: Windows Vista, Java 6, JBoss 4.2.2.GA, JBoss Seam 2.1.1.GA
            Reporter: Markus Merder
            Priority: Trivial


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.toForEachIterator(SimpleForEachIterator.java:135)
	at org.richfaces.iterator.SimpleForEachIterator.supportedTypeForEachIterator(SimpleForEachIterator.java:98)
	at org.richfaces.taglib.ColumnsHandler.prepare(ColumnsHandler.java:304)
	at org.richfaces.taglib.ColumnsHandler.apply(ColumnsHandler.java:489)
	at com.sun.facelets.tag.CompositeFaceletHandler.apply(CompositeFaceletHandler.java:47)
        ....
because supportedTypeForEachIterator(Object o) in SimpleForEachIterator is called with null.
