By the way:
I have other selectOneMenus/valueChangeListener methods, where invoking one valueChangeListener method doesn't affect any other valueChangeListener method, although I also modify other selectOneMenu values in the valueChangeListener method invoked. I always call FacesContext.getCurrentInstance().renderResponse() at the end of each valueChangeListener method, and this causes the lifecycle to continue with the render response phase after the valueChangeListener method is left. But in the one case described, a second valueChangeListener method is invoked after the first, and not renderResponse. > -----Ursprüngliche Nachricht----- > Von: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Auftrag > von Matthias Kahlau > Gesendet: Mittwoch, 14.
