ConstraintViolationException in initial content loading

L.S.,

After a few months of radio silence, we are picking up the Sling-based 
console for ServiceMix again.  With the 2.0.2-SNAPSHOT release of Sling, 
we managed to create a bundle to install the initial content for our 
application, which looks like this:
/apps
  /servicemix
    /dashboard/html.esp
    /exchanges/html.esp
    /navigation/html.esp
/content/servicemix.json

The JSON file contains something like
{
   "jcr:primaryType":"nt:unstructured",
   "sling:resourceType":"servicemix/dashboard",
  
   "exchanges":{
      "jcr:primaryType":"nt:unstructured",
      "sling:resourceType":"servicemix/exchanges"
   },
  
   "navigation":{
      "jcr:primaryType":"nt:unstructured",
      "sling:resourceType":"servicemix/navigation"
   }
}

If we deploy the bundle on Sling now (built from trunk this morning), we 
get this exception:
org.apache.servicemix.smx-sling.servicemix-sling-console (42)] 
org.apache.sling.jcr.contentloader.internal.Loader Cannot load i
nitial content for bundle 
org.apache.servicemix.smx-sling.servicemix-sling-console : no definition 
found in parent node's node type for new node: no matching child node 
definiti
on found for {}servicemix 
javax.jcr.nodetype.ConstraintViolationException: no definition found in 
parent node's node type for new node: no matching child node definition 
found f
or {}servicemix: no matching child node definition found for {}servicemix

I guess something has changed in between versions.  What has changed and 
what do we need to change to get this initial content loaded again?


Thanks,

Gert Vanthienen

+1

as probably everyone using Sling with the WebDAV development style
will run into the nt:folder vs. nt:unstructured issue

I'm wondering if we should create "sling:Folder" instead of an nt:folder 
by default?

Alex,

Thanks for your help!  We managed to get this working again by adding a 
.json file to specify the correct node types for the /content and /apps 
folder.

Regards,

Gert

Looks like the /content folder is just an nt:folder - and thus does
not allow an nt:unstructured child node such as servicemix. You could
add nt:unstructured as a mixin for the /content folder.
