Template is not rendered for null value in array

[pamelafox]

I have many templates like this:

<script id="stats-table-foodtypes-data-tmpl" type="text/x-jquery-tmpl">
{{#each dates}}
  {{#if data}}
   {{=$data}}
  {{else}}
    ?
  {{/if}}
{{/each}}
</script>

They expect an array of values, and they render one thing if the value is there and another thing if it is not. This worked in jQuery templates, but in jsRender, it appears that it does not call the template code at all for a null value. Is this the expected behavior?

This is not currently supported, (in part because of the design for the behavior discussed in #7)

if you model your data to have an array of objects with properties (which may be undefined), rather than simply an array of strings that may be undefined as in ["a",,,"b"]) then you can get something close to your scenario:

{{#each languages}}
    {{#if name}}
        {{=name}}
    {{else}}
        NO
    {{/if}}
{{/each}}

languages: [
    { name: "English" },
    {},
    { name: "French" }
]

Thanks for confirming that. I'll go through and change my data/templates accordingly.

This behavior has been changed, and null or undefined elements in an array are rendered.
