Project: Seam
Issue Type: Bug
Affects Versions: 2.1.2.GA
Reporter: Julien Kronegg

When having a <s:selectItems value="#{myList}"/> , a NullPointerException

java.lang.NullPointerException

From the referenced forum thread and from UISelectItems.java:73, it
turns out that the var attribute is not specified.
Instead of an ugly NPE, Seam should fail gracefully by one of these solutions:
1) throwing a comprehensive exception message
2) having a property "var" as mandatory
