Configuration problems (loading the wrong richfaces-version?

[alex#richfaces1970]

hi,
yesterday I updated the application I am working at and all of a sudden the gui just fades away and leaves me with weird method-not-found errors from the richfaces-library;

thus I have reason to belive that the problem is caused by a library conflict because a few days ago our library-constellation changes the following way:

we migrated from:
richfaces 3.1.4 to richfaces 3.2.0

some other importaint libraries regarding jsf are:
jsf 1.2_04
jsp-api 2.1
jstl 1.1.2

for local testing I deploy the project in Tomcat 6.0.16 webserver, where it wont work (but for some strange reasons with Jetty 6.1.7 it seems to work?)

could you please give me a brave advice why this constellation is making trouble
Thank You

thanks for your effort,
but I guess found the the very reason for the problem. The bug has been caused by eclipse loading-troubles. The automatic deployment of the application didn't work perfectly, so some beans hasn't been upgraded. After not just cleaning the project-build but also closing the project and reopening it, the bug disappeard as fast as it had arrived,
