Multi_select filter not working in AA 1.0.0.pre1 about activeadmin-select2

[jamesrward]

Trying to solve my own problem and it looks like this fork should have solved these issues:
https://github.com/atroppmann/activeadmin-select2/tree/activeadmin-1.0.0

But when I search through the gem it looks like these changes are already incorporated.
I tried changing my gemfile to the following and reinstalled all the gems but it does not appear to make any difference:

gem 'activeadmin-select2', github: 'atroppmann/activeadmin-select2', branch: 'activeadmin-1.0.0'

Having the same issue. It seems that even selecting an option when using :select2_multiple as a filter doesn't work.

Seems like the project is no longer active. not sure how to get this fixed. Right now multiple select doesn't work at all. @mfairburn are you able to look into this?

So sorry for not dealing with this; flooded with work :(

It appears to be working fine on Pre2 so closing this; please re-open if still having issues

Hi

I'm using AA pre4 but get the following problem:

filter :countries, as: :select, collection: proc { Country.all }, label: "Implementation Country"

works fine!

filter :countries, as: :select2_multiple, collection: proc { Country.all }, label: "Implementation Country"

says, "undefined method `countries' for #Ransack::Search:0x007fc4155967b8"

Any idea why @mfairburn? Help much appreciated!
