Subject [jira] [Commented] (SLING-6637) [htl] data-sly-use should not raise an exception when resource doesn't exist
Date Thu, 23 Mar 2017 13:16:41 GMT

    [ https://issues.apache.org/jira/browse/SLING-6637?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15938260#comment-15938260
] 

Feike Visser commented on SLING-6637:
-------------------------------------

This is also a block statement:
{code}
data-sly-test.x="${ prop.x }"
{code}

Re-reading the comments etc, I see both sides of this story.
So why did we not introduce data-sly-resolve?
It looks to me we are mixing things here, I agree with [~kwindszus] on his example.

> 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.
> In addition we can log warning message when this happens.
