I have also took a look at the jsf phases in a JSF portlet application with 2
portlets on a page in Liferay. I have a phase listener in each backing bean of
the portlets implemented an anonymous class printing information at each phase
with this strucutre: <portlet-name> <faces-context-hash-code> <phase>
<bean-hash-code> <bean-class-name>
On the first invokation of the page (no user action), only the following is
done:
Navi Portlet 3775490 : Before Phase: RENDER_RESPONSE(6)
Bean: 3243465 .PDNAVBean
Navi Portlet 3775490 : After Phase: RENDER_RESPONSE(6)
Bean: 3243465 .PDNAVBean
I don't understand this, because my seconde portlet (details) is rendered also.
Now the user has clicked a link in the navi portlet which stores a session
variable which is read from details portlet:
Navi Portlet 32053749 : Before Phase: RESTORE_VIEW(1)
Bean: 3243465 .PDNAVBean

Why is the RENDER_RESPONSE phase called so often ? ..and with different
FacesContext objects ?

Betreff: Re: PhaseListener getting called multiple times
Are you sure that the phaseListener is not more than one time configured?
Put a log statement in the Constructor to see how many instances are created.
