Is this only necessary when using the PPR of Trinidad and if using ajax4jsf there is no need or is this a general "must-do" if using trinidad together with seam correctly. Could you give some more detail on the PhaseListener. Is it necessary to write an own PhaseListener that overrides the methods mentioned about or is it necessary to change code of the current PhaseListener provided with Seam? Afterwards: are there any settings that have to be done in the web.xml or faces-config.xml? Some more details would be greatly appriciated.
