Projectile cache remains empty

[syl20bnr]

In my attempt to lazy load projectile I wrapped some projectile functions which evaluates projectile-global-mode before executing the function [1].

It seems to work but the cache file remains empty, its content is always the same:

#s(hash-table size 65 test equal rehash-size 1.5 rehash-threshold 0.8 data ())

projectile-cache-file value is /home/sbenner/.emacs.d/projectile.cache.

Do you spot anything wrong ?

Found the issue.

First I had to explicitly enable projectile-enable-caching.
Then I had to explicitly call projectile-global-mode (even though I used projectile-commander autoload)
