>                 URL: https://issues.apache.org/jira/browse/SLING-4754
>             Project: Sling
>          Issue Type: Improvement
>          Components: Scripting
>    Affects Versions: Scripting Sightly Engine 1.0.2
>            Reporter: Jörg Hoh
>            Priority: Minor
>
> When content references a sightly component, which is not available, it throws a SightlyException with the message "Unable to generate Java class for template /apps/.../foobar.html".
> Which is correct, but in case the referenced component is just not there, the error handling could be improved to something like "Unable to resolve template %s in the repository".  
> It took me a look in the sourcecode to find the actual root cause, when I got a stacktrace of the generic SightlyException in UnitLoader.java, line 151.
