When a modal window is open, pressing back in browser can change the url and the application state beyond the modal window.

A lot of tickets have been left hanging in the issue tracker through the years. Some of them are still relevant, some of them have been fixed a long time ago and some are no longer valid. To get a better look on what is important and still relevant, we are closing old tickets which have not been touched in a long time.

No further work will be done on this ticket unless someone indicates that it's still relevant.

If this ticket is still relevant to you, please reopen it.

Vaadin Version 7.4.1. Problem still exists. When an modal window is open, it will stay open, and the application state in the background changes.

I succeeded in preventing this by using a custom UriFragmentManager.

Here's the code:

public class TestnavigatorUI extends UI {
	@WebServlet(value # "/*", asyncSupportedtrue)
	@VaadinServletConfiguration(productionMode # false, uiTestnavigatorUI.class)
	public static class Servlet extends VaadinServlet {
	}

	@Override
	protected void init(VaadinRequest request) {
		Navigator navigator = new Navigator(this, new CustomUriFragmentManager(getPage()),
									new Navigator.SingleComponentContainerViewDisplay(this));
		
		navigator.addView("", new MyView("view 1"));
		navigator.addView("test2", new MyView("view 2"));
		navigator.addView("test3", new MyView("view 3"));
	}

	class MyView extends VerticalLayout implements View {
		public MyView(String caption) {
			addComponent(new Button(caption, e -> {
				Window window = new Window();
				window.setModal(true);				
				UI.getCurrent().addWindow(window);
			}));
		}
		
		@Override
		public void enter(ViewChangeEvent event) {}
	}
	
	private boolean isModalWindowShown() {
                return getWindows().stream().anyMatch(Window::isModal);
	}
	
	class CustomUriFragmentManager extends UriFragmentManager {
		private String uriFragment = Page.getCurrent().getUriFragment();
		
		public CustomUriFragmentManager(Page page) {
			super(page);
		}
		
		@Override
		public void uriFragmentChanged(UriFragmentChangedEvent event) {
			if (!isModalWindowShown()) {
				uriFragment = event.getUriFragment();
				super.uriFragmentChanged(event);
			} else {
				Page.getCurrent().setUriFragment(uriFragment, false);
			}
		}
	}
}

Hello there!

It looks like this issue hasn't progressed lately. There are so many issues that we just can't deal them all within a reasonable timeframe.

There are a couple of things you could help to get things rolling on this issue (this is an automated message, so expect that some of these are already in use):

• Check if the issue is still valid for the latest version. There are dozens of duplicates in our issue tracker, so it is possible that the issue is already tackled. If it appears to be fixed, close the issue, otherwise report to the issue that it is still valid.
• Provide more details how to reproduce the issue.
• Explain why it is important to get this issue fixed and politely draw others attention to it e.g. via the forum or social media.
• Add a reduced test case about the issue, so it is easier for somebody to start working on a solution.
• Try fixing the issue yourself and create a pull request that contains the test case and/or a fix for it. Handling the pull requests is the top priority for the core team.
• If the issue is clearly a bug, use the Warranty in your Vaadin subscription to raise its priority.

Thanks again for your contributions! Even though we haven't been able to get this issue fixed, we hope you to report your findings and enhancement ideas in the future too!
