Changing Java class variable of RunAction2 inside of index.jelly

[Nozim Islamov]

Hello, everyone. I have this problem where I want to change the value of Java class variable that is being used for index.jelly, is there any possibility to do so from index.jelly by  calling setter?

Here is the link to github: https://github.com/M1ZoN/manualBuildPromotion

I have a button and a dropdown to change value to. 

Thanks for any help.

The problem was that <bind> works incorrectly with empty classes, i.e. classes without Descriptor, therefore I implemented another class StaplerProxy, and pushed changes to git if someone needs it
