Reloading a tab from another tab in the same TabPanel

[April Pilis]

Hi,

I have this problem that should have a simple solution, but I just don't seem to find it, so maybe you can help.
Is there a way to reload a tab from another tab in the same TabPanel?
Or is there a way to execute a method in another TabScreen class?
(Yes, I am new.)
Any solution would be good, that would help me adjust content of another tab, when changes were made in the current tab.
I would have a click handler of a button in one tab reload (part of) the content of another tab.

Thanks in advance!
