    • loadChildNodes

      public abstract void loadChildNodes()
      This method is called prior to calling getChildNodes() by the Expression Explorer. you need to create the childe node instances and add them to m_childNodes. This method is called when the user toggles a node - at this point of time the next level of nodes is read.

    • getImage

      public String getImage()
      You may specify a special image for this node - otherwise default images are used. Pay attention: the image must refer to the editor's web application - this is the one where images are loaded from by the tool environment. A valid image name e.g. is "/editor/images/icons/lightning.png". Check the corresponding directory of the editor web application in order to see what images are available.
