Improve user experience on JxLoginDialog
i noticed that some users of my app try to authenticate without username and password which of course results in a login error.
To avoid this i would like to disable the login button unless the username and password field contain at least a character - but i found no way to access the according components.
Would it be possible to get access to the components or to fire an event if the contents change ?
PS: My current workaround is to check the contents at the LoginService, but in my opinion would be nice to prevent the login action.
