I spent two days for this error.
Everything works just fine in Firefox.
It doesn't in IE.
When I had found the cause of the problem I remembered how often my mom told me to be attentive.
Compare the Javascript code:
var root = {
name: "hello world",
}
with this one:
var root = {
name: "hello world"
}
See the error?
Can you imagine such a mistake in a large file?
I like JavaScript a lot, but I hate how much it is (and me) error prone.
I hope I have learned the lesson.
