How to remove ! symbol from the URL fragment while using Vaadin Navigator.

Hi,
I am currently working on a Vaadin application, where I am using Navigator class. But the after navigation the URL looks something like this : http://localhost:8081/myapp/#!/accounts
I want to remove the ‘!’ symbol from the URL fragment as per our client requirement. Please somebody help me if it is possible.

Thanks,

Hi, you just need to write a custom NavigationStateManager by extending UriFragmentManager and overriding the getState and setState methods like this:

public void setState(String state)  {
    setFragment(state);
}
public String getState() {
    return getFragment() != null ? getFragment() : "";
}

Then just pass an instance of your custom manager to the Navigator constructor that accepts a NavigationStateManager.

You can also try to explain your customer
why there is the exclamation mark
in the URL, it may or may not be relevant in your case.
