Hi all, We have some code that uses the following: | @In(required = false, value = "#{uiComponent['XXX']}") | Some methods in our bean are called when component XXX does not exist in the ViewRoot, which is why we use required = false. However, this fails now in Seam 2, because the Sun RI throws an IllegalArgumentException from UIComponentBase:588. I imagine it worked with MyFaces because it returned null for invalid components rather than throwing exceptions. I think Seam should catch this exception if doing uiComponent injection and required is set to false. thanks, Daniel.
