The present invention discloses a method for manipulating the presentation of an AJAX tree using an array representing the hierarchical path of a tree node. Such a method can begin with the receipt of a user-request to expand a selected tree node of an AJAX tree in a Web page. Next, it can be determined if the tree node is present in the existing path array. When the tree node is present in the existing path array, the existing path array can be modified for the selected tree node. A new path array can be requested from the AJAX engine when the tree node does not exist in the existing path array. A path array handler can be invoked to expand the AJAX tree using the existing path array.

Technique that enhances the manipulation of an HTML tree presentation by using an array representation of the hierarchical path of a tree node

Embodiments of the present invention provide a method, system and computer program product for hierarchical access control administration preview of access control rights for hierarchically organized content. In an embodiment of the invention, a method for rendering a hierarchical access control administration preview of access control rights for hierarchically organized content can be provided. The method can include rendering a view of hierarchically organized content in connection with corresponding access rights and proposing explicitly assigned access rights for selected content in the hierarchically organized content. The method also can include re-rendering the view to reflect both the proposed explicitly assigned access rights for the selected content and also implicitly resulting assigned access rights for the children of the selected content.

Hierarchical access control administration preview

Embodiments of the present invention address deficiencies of the art in respect to access control and provide a method, system and computer program product for access control and entitlement determination for hierarchically organized content. In an embodiment of the invention, a method for access control and entitlement determination for hierarchically organized content can be provided. The method can include selecting a node in hierarchically organized content, inferring entitlements for direct descendants of the selected node based upon expressly conferred permissive access rights amongst ancestors and descendants of the selected node and expressly conferred impermissive rights amongst descendants of the selected node. Finally, the method can include applying the inferred entitlements in a view to the hierarchically organized content.
