I am on AEM 6.3.1.2.
If I use *data-sly-resource* w/ dynamic variable which is null or empty, I get
a *RecursionTooDeepException* runtime. The stack looks something like this

It seems like the resource include implementation is scanning the page's whole
resource tree. I think the behavior is similar to what's mentioned in the
thread [here|https://forums.adobe.com/message/9720147#9720147]
I can get around this by putting a *data-sly-test* in the same sly tag as the
*data-sly-resource* tag.
(This is a follow up on discussion
[here|https://twitter.com/sagarsane/status/999675314937778176])
Please let me know if I should add any more details.
Thanks!
