    • initSelection

      public void initSelection()
      Try to determine which model should be used as initial selection. First, retrieve the model that represents the actual selected node and see if it is valid. If so, select it and return, if not, see if a last visited model is set and if so select it and return. If not, see if a default model is set, if so, select it and return. If not, fallback to the model currently in the selectionModelReference. TODO: We should try and see if the last-visited model is visible in the browser, if not, go on to default model

    • getBaseModel

      protected org.apache.wicket.model.IModel<Node> getBaseModel()
      A hook that allows subclasses to specify a default location.
      Returns:
      An model used as default initial selection

    • getSelectedModel

      public org.apache.wicket.model.IModel<Node> getSelectedModel()

    • getInitialModel

      protected abstract org.apache.wicket.model.IModel<Node> getInitialModel()
      Return the initially selected model
      Returns:
      The model that is initially selected

    • onSelect

      protected void onSelect(boolean isValid)
      This method is called when a new model is selected.
      Parameters:
      isValid - If the model is considered a valid selection model, value will be true, otherwise false.

    • isValidSelection

      protected boolean isValidSelection(org.apache.wicket.model.IModel<Node> targetModel)
      This method determines the validity of the selected node in context of this dialog. Null values are always considered invalid. Validity is based on whether the nodetype is allowed and if the node is linkable.
      Parameters:
      targetModel - The model providing the node to be validated.
      Returns:
      If the provided node is a valid dialog selection.

    • isLinkable

      protected boolean isLinkable(Node node) throws RepositoryException
      Determine if the provided node is of nodeType["mix:referenceable"] and if it's not a hippo:document below a hippo:handle.
      Parameters:
      node - Node to test for linkability
      Returns:
      If this node is linkable
      Throws:
      RepositoryException - Something went wrong in the repository

    • isValidNodeType

      protected boolean isValidNodeType(Node node) throws RepositoryException

      Determine if the node type of the provided node is valid. In case a handle is passed, it will use the nested hippo-document node, or, if none found (in case of a delete), return false.

      By default, only documents are considered valid. To use more fine-grained validation, like for example, only allow document types "foo" & "bar", or allow folders as well, a list of allowedNodeTypes can be set during construction of the dialog.

      Parameters:
      node - The node to be validated. If it is of nodeType["hippo:handle"], the first childNode with the same name will be used instead.
      Returns:
      If the node type is considered valid.
      Throws:
      RepositoryException - Something went wrong in the repository

    • getLastVisitedFromPreferences

      protected org.apache.wicket.model.IModel<Node> getLastVisitedFromPreferences()
      Check the IPreferencesStore for a last visited location (a node path) and if found, return it in a new JcrNodeModel, otherwise return null.
      Returns:
      A new JcrNodeModel pointing to the last visited location (a node path) or null

    • getFolderModel

      public org.apache.wicket.model.IModel<Node> getFolderModel()
