currentNode object gives NullPointerException

In my component's JSP, if I want to reference the current node using currentNode object, it throws a NullPointerException and the whole component then throws a ScriptEvaluationException

My component JSP does have the global.jsp included at the top. I guess currentNode object is created by the global.jsp

Strangely, the component throws these exceptions only in a particular site. It works fine in others.

What possible could be the reason for this ? In what conditions does the currentNode object be NULL ?

Solution

  • Maybe your component is a synthetic resource? If you have include tag like this:

    <cq:include path="mynode" resourceType="myapp/components/somecomponent" />

    and mynode doesn't exist, the included component will be renderer, however you can't referer to the node properties in somecomponent code.

    In this case resource variable will be a SyntheticResource and currentNode will be null.

    Update:

    If you don't really need the currentNode but QueryManager object (as your comment says), you can use resourceResolver object to get it:

    resourceResolver.adaptTo(Session.class).getWorkspace().getQueryManager()
