Why do I get the error message:
Error: [$interpolate:noconcat] Error while interpolating: '{{ content.src }}'
Strict Contextual Escaping disallows interpolations that concatenate multiple expressions when a trusted value is required.
with this syntax:
<div id="content" class="content">
<ng-include src="'{{ content.src }}'"/>
</div>
And the model is
$scope.content = {};
$scope.content.src = "content.html";
