   Uncaught Error: Assertion Failed: The metamorph tags, metamorph-28-start and metamorph-28-end, have different parents. The browser has fixed your template to output valid HTML (for example, check that you have properly closed all tags and have used a TBODY tag when creating a table with '{{#each}}')

code snippet:

<div class="panel-body">
 <div class="row">
    {{#each}}
      <div class="col-xs-3">
        <label class="control-label">{{fieldname}}</label>
      </div>
      {{#if fullcolumn}}
          <div class="col-xs-9">
            <input type="text" class="form-control" placeholder="full">
          </div>
      {{else}}
          <div class="col-xs-3">
            <input type="text" class="form-control" placeholder="half">
          </div>
      {{/if}}
      {{#if newrow}} 
          </div>
          <div class="row">
      {{/if}}
    {{/each}}
  </div>
 </div>
