-----------------------------------

             Summary: [htl] data-sly-use should not raise an exception where 
resource doesn't exist
                 Key: SLING-6637
                 URL: https://issues.apache.org/jira/browse/SLING-6637
             Project: Sling
          Issue Type: Bug
          Components: Scripting
            Reporter: Feike Visser


Following code: 

{code}
<sly data-sly-use.x="${ 'x/y/z' }"/>
{code}

You get now the following exception:
{code}
org.apache.sling.scripting.sightly.SightlyException: No use provider could 
resolve identifier x/y/z
{code}

In practice you want to have a null-value assigned to x, now developers will 
make a lot of checks to make sure the resource does exist.
