I have a application created using vaadin, a list of button A, button B, button Ceach button will opened a Tab.
The problem is if I open the application in different computer. the tab that already open will not be opened again
example. computer 1 opened click button A . it will opened and display Tab A
computer 2 cannot opened Tab A
if computer 2 click button C, as long it is not opened in computer 1, Tab C will be opened and display
computer 1 try to click button C, it will not opened Tab C.
it seem theirs only one instance running in the server.
