POdust.js losing 'this' context in handlers?
text
Body
copied!<p>I have a [seemingly] trivial dust.js template. The context object I am using to render the template contains a handler which references another item in the context object. I also include a toString handler, which also references another item in the context object.</p> <p>Template:</p> <pre><code>{error} <pre> {#error.getStackTrace} {.}{~n} {/error.getStackTrace} </pre> </code></pre> <p>Context:</p> <pre><code>{ error: { st: ['a','b','c'], msg: 'This is an error message', getStackTrace: function () { return this.st; }, toString: function () { return this.msg; } } } </code></pre> <p>Rendered:</p> <pre><code>This is an error message<pre></pre> </code></pre> <p>If I reference <code>{#error.st}</code> directly, it renders correctly:</p> <pre><code>This is an error message<pre>a b c </pre> </code></pre> <p>If I inspect 'this' inside of the getStackTrace() handler, it is pointing back to DOMWindow. It is interesting, however, that invoking toString() implicitly, it is scoped correctly. If I explicitly invoke toString() <code>{error.toString}</code>, then the scope jumps back to DOMWindow.</p> <p>The only reason this is a problem, (why I cannot access <code>error.st</code> directly) is because the st array is actually stored in a Qooxdoo property, and I only have access to the generated getter. The above example mimics the actual object as simply as I can.</p> <p>Is this a bug in dust.js? Is it losing the correct scope in handlers? Or am I missing something in the dust.js docs to retain scope?</p>
