Comment 2 for bug 1808268

Thanks, Jane!

I pushed a sign-off branch that includes a minor tweak commit:

http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/berick/lp1808268-eg2-grid-disable-toolbar-action

The extra commit renames the "disabled" attribute to "disableOnRows" to avoid any confusion that might arise from "disabled" typically being a boolean variable instead of a function returning bool.
