Situation

Imagine the following dataset:

{
	value: '1st level value', 
	context: {
		value: '2nd level value'
	}
}

Applied on this template:

<p>{{value}}</p>
{{#context}}
	<p>{{value}}</p>
{{/context}}

This output is produced:

1st level value
1st level value

Reasons

That happens, because the 'value' of the global context is rendered in the whole template before the context section gets rendered due to the order of processing in renderRecursive. So after renderVariables, the template looks like this:

<p>1st level value</p>
{{#context}}
	<p>1st level value</p>
{{/context}}

Evaluation

An advantage of this behavior is, that static values referring to an upper context inside big lists only have to be rendered once. The disadvantage is, that names can't be re-assigned inside sections.

Solutions

Option 1

Change order of processing in renderRecursive. This has to be checked for undesired side-effects.

Option 2

Introduce backwards-context with a double-dot like this:

{{#context}}
	<p>{{value}}</p>
	<p>{{..value}}</p>
{{/context}}

This should then produce the following output:

2nd level value
1st level value
