Upgrading a project to dojo 1.7.2 from 1.6.0.  While I could simply point to the new version (it seems quite backward compatible), I think it’s time to switch to the new AMD compatible require / declare syntax.

Step 1.  Pointed at the CDN and set async to true:

<script type="text/<span class=">// <![CDATA[
// <![<span class="hiddenSpellError" pre="">CDATA</span>[
// ]]></script>
javascript" src="//ajax.googleapis.com/ajax/libs/dojo/1.7.2/dojo/dojo.js"
// ]]></script>
 data-dojo-config="async: true, parseOnLoad:true">
</script>

Immediately the async: true caused dojo is undefined errors from dojo.byId and dojo.require statements.

// A slide out tab
dojo.require("dojo.fx");
dojo.addOnLoad(function() {
    dojo.animateProperty({
        node:"slideOutBox",
        properties: {
            height: 0
        }
    }).play();
});

The fix was pretty easy

Step 2. Change dojo.require to require and move dojo.addOnLoad into

require([“dojo”,”dojo/fx”, “dojo/domReady!”], function(fx){
});

Upgrading custom dojo build to 1.7.2

First build overwrote dojo.js, oops, which gave this unhelpful error,

js: uncaught JavaScript runtime exception: ReferenceError: "require" is not defined.

Note: I should have finished this post a year ago when I was doing the upgrade.  There were a few more issues I ran into but it’s a bit fuzzy now.
