Invalid recursion selector value 'autoComplete'

Hi,

I registered a Sling-Servlet to generate JSON when a resource of the resource type "my/resource/type" is called with the selector "autoComplete" and the extension "json":

@Service @Component() @Properties(value = { @Property(name = "sling.servlet.resourceTypes", value = "my/resource/type"), @Property(name = "sling.servlet.selectors", value = { "autoComplete" }), @Property(name = "sling.servlet.extensions", value = { "json" }), @Property(name = "sling.servlet.methods", value = "GET") })

When I call: http://localhost:4502/content/xyz/global/corporate/en/search.autoComplete.json?searchText=ro        

(which resource is of the correct resource type) I get the following exception:

Invalid recursion selector value 'autoComplete' Cannot serve request to /content/xyz/global/corporate/en/search.autoComplete.json in org.apache.sling.servlets.get.DefaultGetServlet 0 (2015-01-07

For some reason it seems that my "AutoCompleteControllerServlet" is never called. The Problem seems to be the "json" extension. As soon as I specify this the DefaultGetServlet seems to handle the request.

When I specify "html" as the extension my Servlet is called but the following HTML comment is appended to the JSON response generated in my Servlet, which renders the JSON invalid.

<!--cq{"decorated":false,"type":"xyz/pages/search","path":"/content/xyz/global/corporate/en/search/jcr:content","selectors":"autoComplete","servlet":"AutoCompleteControllerServlet","totalTime":13,"selfTime":13}-->

1. Why isn't my servlet called when I specify "json" as extension?

2. Is there a way to tell CQ not to add the HTML comment when I specify "html" as extension?

To use the json extension would be my prefered solution.

Any hint to get regarding this problem is appreciated,

Ronald

    HI Ronald,

    Have [1] handy always.

      /content/xyz/global/corporate/en/search is of type page your servlet never pickup.  If needs to pickedup you need to write proxy.jsp   Instead using /content/xyz/global/corporate/en/search/jcr:content/<component node name which of type  my/resource/type>.autoComplete.json?searchText=ro will work.

    Hi Sham,

    thanks a million for your answer and also for reminding me of the Sling Script Resolution Cheetsheet.

    You are right: The resource "/content/xyz/global/corporate/en/search" does not have a resource type but only has the "jcr:primaryType" of "cq:page" whereas "/content/xyz/global/corporate/en/search/jcr:content" is of the resource type "my/resource/type".

    Therefore when I call "http://localhost:4502/content/xyz/global/corporate/en/search/jcr:content.autoComplete.json?searchText=ro" everything works like a charm.

    Thanks again,

    Ronald
