[jira] [Commented] (SLING-8170) Allow Sling servlets to declare a resource super type

["Julian Sedding (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLING-8170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16719976#comment-16719976 ] 

Julian Sedding commented on SLING-8170:
---------------------------------------

[~radu.cotescu] The proposal sounds reasonable, and I like that it brings servlets and scripts on par in this respect.

Contrary to your proposal, for the reason of consistency, I suggest to call the new registration property {{sling.servlet.resourceSuperTypes}} (i.e. plural). All other registration properties (except "prefix") are already using plural and allow multiple values. I assume that would require the implementation to register the servlet for each combination of resource-type and resource-super-type (+ selectors, extensions etc).

> In Sling scripts and servlets are equal [0]. However, currently a servlet cannot declare a resource super type property, in order to allow delegation / overlaying at runtime to another servlet, similar to how component scripts can do it through the {{sling:resourceSuperType}} optional property.
> Adding support for another registration property - {{sling.servlet.resourceSuperType}} - that accepts a String as value would allow to introduce a backwards compatible overlaying and inheritance capability. This property should only be considered for the registration together with the {{sling.servlet.resourceTypes}}.
