Seam no longer compatible with facelets 1.0.14?

[andrew.rw.robinson]

I just tried to upgrade Seam from 1.1.0 to 1.1.6 and I can no longer deploy our EAR/WAR. We are running facelets 1.0.14 and cannot switch to 1.1.x at this time due to compatibility breaking changes in 1.1.x. Seam is now throwing:

10:44:47,253 ERROR [[/OSoft]] Exception sending context initialized event to listener instance of class org.jboss.seam.servlet.SeamListener

It looks like there was an undocumented compatibility breaking change in Seam of requiring 1.1.x of facelets. Is this true? If so, what is the latest version of Seam that can run on facelets 1.0.x? Also, is there any way to find out these types of non-backwards compatible changes in Seam releases (it was not in the release notes that I saw)?

Also would it be possible to fix this in 1.1.7 so that only facelets 1.0.x is required instead of 1.1? 1.0.14 is considered a stable production facelets release and IMO should be supported if possible.

Thank you

Just tried 1.1.1, and it looks like the problem is there as well. This is unfortunate as 1.1.1 has bug fixes for bugs that are affecting us.

[andrew.rw.robinson]

It looks like the problem is:

org/jboss/seam/ui/facelet/FaceletsRenderer.java

I don't see any code referring to this class or any configuration referring to it (including the @Name("renderer")). What is the purpose of this class?

It is used for rendering email.

My recommendation is to update your facelets version.

[andrew.rw.robinson]

We cannot upgrade facelets due to the fact that 1.1 breaks backwards compatibility.

I deleted that class and rebuilt the jars for 1.1.6 and it seems to work. Is email the only thing that will be broken without that class?

[gavin.king]

yes
