Button Addon: inst.state[pane] is undefinined during _load() when called from layout() #21
Description
When using jquery.layout 1.4.3, upon initial page load on Firefox 38.6 or later, the _load() method within the jquery.layout.buttons.js is caught by Firefox 38.6 with Firebug 2.0.19 as having an undefined 'inst.state[pane]'.
The 'pane' value is 'n' in my scenario and there isn't a code path from calling 'layout()' on the main jquery.layout which initializes the inst.state[pane] properly.
Note: Firefox + Firebug cause this where Chome and IE didn't.
inst.state[pane].pins = [];
