Versions <= 1.2.9 are OK.
Versions >= 1.3.0 not working.

The layout.html is

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <title>AdminLTE 2 | Dashboard</title>
        ...

This index.html file works fine.

    <head>
        <title>Task List</title>
    </head>

And this one won't work.

<head><title>Task List</title></head>

Here is the error message.

Maybe this was caused by

            removeChildWithWhitespace << { child ->
                if (child) {
                    def children = delegate.children
                    def index = children.indexOf(child)
                    delegate.removeChild(index)
                    delegate.removeChild(index - 1)
                }
            }

But I'm not sure.

Thanks for the bug report! Your suspicions of the buggy code might be right - that thing guesses what the whitespace for a section is, but if there is none (like in your example template), then it errors.

I'll fix this in an upcoming patch.

Fixed with a simple index > 0 check. I've uploaded a 1.3.2-SNAPSHOT version of the layout dialect with this fix.
