Composite component required attribute throws exception in Mojarra 2.0.3

Question

I\'ve been playing around with JSF 2.0 composite components but I\'m a bit confused as to what the require attribute in the composite:attribute tag is meant to

Answer 1

We have simular issues with required="true" in combination with @ViewScoped bean.

I our case the bean no longer behaves like a @ViewScoped bean (new constructor call every time).

Your problem might be that because the bean looses its scope the variabels are null again?

Either case the only awnser I can give you is to not use required="true" or use a @SessionScoped bean.

(Possibly this relates to the problem of Mojarra not being able to handle bindings to properties in @ViewScoped beans)
