To apply this new features in an exixting page you must remove all the code of the old version and re-apply the extension. This because in this new release I modify the code inserted in the page to add new parameters and in this case DW don't recognize the old code and is unable to detect the extension in the page.

To apply this new features in an existing page you must only double-click on the extension label in the server behavior panel, and after the extension panel is open click on the Ok button. This will update all the files in the dwzTreeView folder and the new features will be available.
