Doesn't Work for ST 2.0.1

[neotericneoteny]

I need an accordion layout for a client project and really love this implementation. Unfortunately it doesn't appear to work with Sencha Touch 2.0.1 and upgrading to 2.2 won't take place for about 3 months or so. What needs to be done to support ST 2.0.1 (again)?

Thanks!
