I have a JSF page home.xhtml with some JSF components / view and let's say it is currently loaded in a (Firefox) browser popup window named test-popoup-win. Now I try to access the same page/url, home.xhtml?query=JSF, with additional url parameters, from another (Firefox) browser window, which is supposed to load different/new set of components, based on new search context (?query=JSF). And this loads home.xhtml in the same browser popup window, named test-popup-win, overriding the previous JSF components / view. In the backend servlet code, I am actually redirecting to the same page, home.xhtml?query=JSF.
But instead of showing the new view, it throws the following error. The log shows that a property was not found. I can confirm that the property not found, belongs to the old view / bean. But if I click continue on my custom error page, I get the new view without any issue.
Please help/advice, by suggesting a way which could clear previous view cleanly and load the new view or any other way for issue fix. Let me know if I am missing any inputs. Thank you very much.
Is there any good way to debug this kind of JSF issue ?
Update: One may-not-be-good temporary workaround (I dont even call it solution) could be to ignore the exception in FacesErrorHandlingServlet class. I am still trying/looking for a good solution, please share if you have one

Make sure you don't invoke unexisting getter/setters on your beans, or make sure all beans share the same basic properties (inheritance) or wrap your components (which try to access your getters) with
rendered="#{myBean.typeOfBean eq 'theOneWithThatProperty'}"or something like that...
