In Touch UI dialog's, the dynamic dropdownlist are loaded through data sources, sometime we may need to get the current page URL from where the dialog is opened to load the dropdownlist data.
String path= request.getParameter("item");
Returns the content path with out jcr:content, e.g /content/test/en/home
String path = (String) request.getAttribute(com.adobe.granite.ui.components.Value.CONTENTPATH_ATTRIBUTE);
Returns the path with jcr:content, e.g /content/test/en/home/jcr:content
