Description Cedric Brun CLA 2011-11-10 04:24:46 EST 
From this :


[template public id(t: Task)]
[t.ancestors()->filter(Task).position()->sep('-')/]-[t.position()/]
[/template]

[template public position(obj : OclAny)]
[precedingSiblings()->size()/]
[/template]

I get a NPE :


java.lang.NullPointerException
