Why this works: Meteor-Blaze #with and data context? -

i wonder why following thing outputs 'hello' instead of 'bye'???

template:

<template name="example">     {{#with datacontext}}         {{say}}     {{/with}} </template> 

template helper:

template.example.helpers({     datacontext: function() {         return {             say: 'bye'         };     },     say: function() {         return 'hello';     } }); 

(meteor 1.1.0.2)

the shortest answer helpers have preference on data context.

if rename 1 of them else should solve problem.

the order lookup goes is:

1. the data context (if contains .). {{say}} not.
2. the template's helper. {{say}} has helper say.
3. a template
4. a global helper such defined template.registerhelper.
5. the data context

so if first isn't found, goes down list until finds something
