Dynamic Generation of Back URL

Question

I opened a tar on the dynamic generation of a back URL because the information on the forums has been incomplete and without solid examples for my needs. They provided the following information:
"So far I have found a few methods to achieve what you are wanting to do....
With the plsql web toolkit there is a function called owa_util.get_cgi_env. You can use this to grab many different parameters. You could use this function to reconstruct the actual url that you are on.
For example, request_protocol, server_name, server_port, script_name, and path_info could all be concatenated to create the original url.
Or you can also use the owa_util.get_cgi_env function in the called screen to grab the url of the calling url. So essentially the url you want to go back to. This parameter value is called HTTP_REFERER and it contains the complete url. The only issue with this one is that you can not reference it until you are already in the second page. Therefore you could not pass it to that second page when building the page.
Documentation on the above is included in the 9iAS documentation set since it is part of the plsql toolkit and not specific to Portal. The url to this documentation is:
http://otn.oracle.com/docs/products/ias/doc_library/1022doc_otn/apps.102/a90101/toc.htm
I will continue searching for anything specific to Portal and its api's but up to now I have not seen anything specific to this."

Dear Kishore,
Write the following code in the wdDoModifyView(...) method..and replace YourModelNode with actuals
if (firstTime) {
// Get the reference to the UI rool elemnet
                      IWDTransparentContainer rootElement = (IWDTransparentContainer) view.getRootElement();
// Set the layout manager to MatrixLayout
     rootElement.createLayout(IWDMatrixLayout.class);
// Get the metadata of the node
     IWDNodeInfo nodeInfo = wdContext.getYourModelNode().getNodeInfo();
     for (Iterator iter = nodeInfo.iterateAttributes(); iter.hasNext();) {
          IWDAttributeInfo attributeInfo = (IWDAttributeInfo) iter.next();
          IWDLinkToURL LinkToURL=(IWDLinkToURL) view.createElement(IWDLinkToURLclass,attributeInfo.getName() +"LinkToURL");
          LinkToURL.setText(attributeInfo.getName());
                                          LinkToURL.setReference(attributeInfo.getReference());
          LinkToURL.createLayoutData(IWDMatrixHeadData.class);
          // Add the LinkToURL to the UI
          rootElement.addChild(LinkToURL);
Hope it helps!
Warm Regards
