Adianti does an autoload, lookups at its translation table, and creates a class alias in run time. Sadly this can't be handled by the PHP Editor in general, since it does not know that for example TPage is an alias to Adianti\Control\TPage. (the namespace is a part of the class name in PHP, we can't simply ignore it)
We could implement a "smart" mechanism that would recognize Adianti, but it would take some time for us to do.
I can suggest two workarounds for now:
I hope it helps. And we'll look into better support of Adianti in the future update.
