Ah ok so you do a redirect from abc:null to abc:1 and do not want the redirect to appear in the history.
You could try to implement a custom Historian<http://google-web-toolkit.googlecode.com/svn/javadoc/2.3/com/google/gwt/place/shared/PlaceHistoryHandler.html#PlaceHistoryHandler(com.google.gwt.place.shared.PlaceHistoryMapper, com.google.gwt.place.shared.PlaceHistoryHandler.Historian)> by implementing the interface or extending DefaultHistorian (thats the class that interacts with the History class) and set it to your PlaceHistoryHandler. Your custom Historian implementation could then check for these special cases and just do not call History.newItem() if its ask to put abc:null to the history. Maybe you could also just treat abc:null as "select the first entry in the list or select nothing if list is empty". Imagine you have a list with items whose ids are 3,1,2. If you go to abc:null you would select 3 as its the first entry. If the user then selects 1 you would have abc:1. Now the user selects 3 again and the url would be abc:3. So you have two urls/tokens that would result in the same selection and the back button should work like expected. The only downside is that its probably not useful if you can add items to the list (what happens if you insert a new item at the first position? When hitting the back button you would select the wrong item once you reach abc:null again). -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
