Hello Benoît,
In the past similar problems like the one reported by you was related to the prepend
mechanism.
Please check if the file application-j2ee-engine.xml of your dpu which contains the phaselistener has the following reference:
<!-- JSF 2 Implementation --> <reference reference-type="hard" prepend="true"> <reference-target provider-name="sap.com" target-type="library">wec~frw~tc~jsf~lib</reference-target> </reference>
If you want, you can send me the ear file of your dpu project for further investigation.
My email is sascha.scherer@sap.com
Best regards,
Sascha
