问题 Unfortunately, primefaces accordionPanel doesn't works well in version 2.2.1 if you are trying to create tabs dynamically. This is my case, I need to create accordions if the user clicks an add icon, and remove if he clicks on x icon. No problem, I've created my own composite component, like you can see here: <c:interface> <c:attribute name="titulo" default="" required="false" /> <c:attribute name="renderizar" default="true" required="false" /> <c:attribute name="width" required="false"

问题 This question may be more of the type "conceptual" or "I don't understand JSF". My scenario: I have a JSF Page ( index.xhtml ) where I use a p:accordionPanel (but I don't think it matters what component it is). What I want to do is to set the activeIndexes of it. <p:accordionPanel multiple="true" activeIndex="#{myController.getActiveIndexesForSections('whatever')}"> // bla bla... </p:accordionPanel> And the (simplified) method in the backing bean: public String getActiveIndexesForSections
