CQ5 - Masquage d'un onglet à l'intérieur d'une boîte de dialogue de composant en fonction du groupe d'utilisateur?

Ceci peut être accompli avec un servlet et une boîte de dialogue de l'écouteur d'événement.

La fonction écouteur fait une demande à la servlet, en passant l'ID de l'utilisateur courant et le groupe de votre choix. La boîte de dialogue de l'onglet peut être masqué basé sur la réponse de servlet.

Voici un exemple dialog.xml pour un CQ5 composant:

<?xml version="1.0" encoding="UTF-8"?>
<jcr:root 
    xmlns:cq="http://www.day.com/jcr/cq/1.0" 
    xmlns:jcr="http://www.jcp.org/jcr/1.0"
    jcr:primaryType="cq:Dialog" 
    xtype="dialog">
    <listeners jcr:primaryType="nt:unstructured"
        loadcontent="function(dialog) {
            var url = '/bin/member.json';

            //check if current user belongs to administrators group
            url = CQ.HTTP.addParameter(url, 'userId', CQ.User.getUserID());
            url = CQ.HTTP.addParameter(url, 'groupId', 'administrators');

            var result = CQ.HTTP.eval(url);

            if (!result.isMember) {
                //hide "tab2" if user is not an administrator
                dialog.findByType('tabpanel')[0].hideTabStripItem(1);
            }
        }" />
    <items jcr:primaryType="cq:WidgetCollection">
        <tab1 jcr:primaryType="cq:Widget" title="Text" xtype="panel">
            <items jcr:primaryType="cq:WidgetCollection">
                ...
            </items>
        </tab1>
        <tab2 jcr:primaryType="cq:Widget" title="Image" xtype="panel">
            <items jcr:primaryType="cq:WidgetCollection">
                ...
            </items>
        </tab2>
    </items>
</jcr:root>
