I am getting the following js error on the grid:

this.grid.selModel has no properties
grid-min.js (line 65)
grid-min.js (line 65)
grid-min.js (line 68)
grid-min.js (line 4)
grid.html (line 99)
event-min.js (line 1)

I have YUI 0.11.3 and just running the example grid.

These are my includes:

<script type='text/javascript' src='/base/lib/yui/yui/build/yahoo/yahoo-min.js'></script>
<script type='text/javascript' src='/base/lib/yui/yui/build/event/event-min.js'></script>
<script type='text/javascript' src='/base/lib/yui/yui/build/dom/dom-min.js'></script>
<script type='text/javascript' src='/base/lib/yui/yui/build/dragdrop/dragdrop-min.js'></script>
<script type='text/javascript' src='/base/lib/yui/ext/yui-ext.js'></script>
<script type='text/javascript' src='/base/lib/yui/ext/build/grid-min.js'></script>
<script type='text/javascript' src='/base/lib/yui/ext/build/element-min.js'></script>
<script type='text/javascript' src='/base/lib/yui/ext/build/yutil-min.js'></script>
<link rel='stylesheet' href='/base/lib/yui/ext/resources/grid.css'>

I can not find where selectModel is defined. this.selModel = selectModel

Thanks for your help. This looks like a great lib.
