Re: AppCacheBuster and cross application access?

I declare the other application in the bootstrap resource roots:

data-sap-ui-resourceroots='{
"own.app": "./", 

"other.app": "../App2/"
}'

and I also declare it for the AppCacheBuster:

data-sap-ui-appCacheBuster='["./", "../App2/"]'

Then i would list the module from App2 as a dependency for the module which wants to use it.

sap.ui.define(["other/app/CommonUtils"],
   function(CommonUtils) {

  CommonUtils.doSomething();

}

That's how I think it should work. Didn't try it yet though.
