I'm experimenting with Shindig -- the PHP version, since the Java version
won't install properly under JBoss 5, and I don't have the patience to
start downloading various Java app servers and see which will work.
I've noticed that the SVN trunk version fails with even basic gadgets. The
issue appears to be the order in which the JavaScript is included. Namely,
auth-init.js is included before config.js (both in
features/src/main/javascript/features/core.*), but auth-init.js contains
the line (28):
shindig.auth = new shindig.Auth();
which, in turn calls (auth.js line 159):
gadgets.config.register("shindig.auth", null, init);
The problem is, of course, that gadgets.config doesn't exist yet (it's
defined later in config.js). As a result, we get the JavaScript error
"Result of expression 'gadgets' [undefined] is not an object" (Safari) or
"Error: gadgets is undefined" (FireFox).
If someone can provide me with a pointer to the area of the code where the
order of including these pieces of JavaScript are, I'd be much obliged. I
will provide a patch if I can fix it. Incidentally, both Safari and
FireFox seem to abort processing the JavaScript processing in the HTML
head block at that point, leaving 'gadgets' wholly undefined at that
point.
Here's a gadget that demonstrates the problem:
<?xml version="1.0" encoding="UTF-8"?>
<Module>
<ModulePrefs title="Hello" description="An example of a simple
gadget" author="James McIninch"
author_email="[email protected]" />
<UserPref name="firstname" display_name="Your name"
datatype="string" default_value="stranger" />
<Content type="html" preferred_height="50" preferred_width="200">
<![CDATA[
<script type="text/javascript">
var prefs = new gadgets.Prefs();
var name = prefs.getString("firstname");
document.getElementById("placeholder").innerHTML =
name;
</script>
Hello, <span id="placeholder">name goes here</span>!
Er, did that work?
