@In(required = false, value =

[jazir1979]

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.

It looks like this could be fixed with a very simple patch to org.jboss.seam.faces.UIComponent to catch the IllegalArgumentException and return null.

BTW- I'm using the workaround of looking up the components myself via the FacesContext ViewRoot in the methods that require it.
