[Idiot] Having a bit of trouble with the GUI after the update.

[TerraPrimal]

So I was few versions behind (1.1.3) and I have updated and added the new InventoryManager, however I still can't get it to work.
The GUI loads fine and doesn't override the borders (thanks for that) but there is no response from the icons or the pagination prev, next.
I guess I am missing something obvious and need it spelt out for me -_-.

I had added a .gif below and a snippet of code (just basic pagination).

And this is my main class

The SmartInvs-1.2.1.jar is in my plugins folder as well as depend: [SmartInvs]
The above method throws this error: https://pastebin.com/DGGdutXU

Hi, you must call the invManager.init() method before using it :p

Of bloody course, in my code I am registering my listener class PRIOR to init the InventoryManager... ofc it throws an error...

Thank god this moment of idiocy isn't publicly view-able, for like... ever :D
