Hi

I am open multiple intances of same window with different bindings.  
This works fine but I would like to also swap window to another one and still keeping other instances open.  
It seems to be working but some times it closes all same name windows = all instances.  
Is there any way to avoid this?

Yes, there is a way to avoid this issue. Take a look at this thread that talks about the issue more:

[http://www.inductiveautomation.com/forum/viewtopic.php?f=70&t=5208&p=13671&hilit=instance#p13671](http://www.inductiveautomation.com/forum/viewtopic.php?f=70&t=5208&p=13671&hilit=instance#p13671)

Basically, the openWindowInstance returns a window object you can store to swap or close later. Hope this helps.
