I have a custom template. Let it be called T1.  
It can be used on different windows in containers with different paths

inside T1 there is a template canvas TC1

Inside the canvas there is a template T3

What is the best way to access the parameters and functions of the template T1 from the template T3?

As far as I understand, the .parent link does not work for the transition from T3 to CT1  
I can access the root container of the current window, but the path to the T1 template inside this window is not known beforehand

Use more than one `.parent` dereference. There is more than one Swing layer in between.
