ICEsoft.org Forums: ICEfaces, ICEmobile, ICEpdf

When I try to integrate ICEfaces with my Seam + SunRI application I get the NullPointerException listed below.

The problem can be reproduced using the "icefaces" example bundled witih SEAM 1.1.GA. Reproduction steps are detailed here on the JBoss Seam forum.

This thread mentions that 1.5.2 will address a bunch of Seam integration issues. Any chance this one is included?

Thanks.

This appears to be a JSF 1.2 compatibility issue; we'll reproduce the configuration and investigate (although JSF 1.2 is not yet officially supported with ICEfaces).

Adding the constructor as mentioned on the JBoss forum appears sufficient to get the application running (other fixes present in ICEfaces 1.5.2 are likely also required).
