Radu Cotescu updated SLING-9783:
--------------------------------
Description:
SLING-9696 introduced a side-effect into the HTL compiler, which doesn't
correctly check if an attribute should be displayed or not when the evaluated
expression returns a {{null}} value.
The following code example will generate a NPE:
{code:html}
<a href="${pojo.null @ context='unsafe'}>Click</a>
{code}
if the {{pojo.null}} actually returns {{null}}, since the {{unsafe}} context
will return the original passed value.
