I'm trying to upload files with the upload script to a space I created (Incoming Files). I want to know how many children this space already has, so I can generate a unique prefix to avoid double names.
However, I get a null pointer exception when I try to access the children property of the space I created. I can access the children property of already existing space with no problem (eg Guest Home). See he code below:

  incoming1 = companyhome.childByNamePath("Guest Home");
  incoming2 = companyhome.childByNamePath("Incoming Files");
  logger.log("incoming 1: " + incoming1.properties.name);
  logger.log("incoming 2: " + incoming2.properties.name);
  logger.log("incoming 1 children: " + incoming1.children.length);
  logger.log("incoming 2 children: " + incoming2.children.length);

This gives the following output:

16:33:34,919 DEBUG [org.alfresco.repo.jscript.ScriptLogger] incoming 1: Guest Home
16:33:34,929 DEBUG [org.alfresco.repo.jscript.ScriptLogger] incoming 2: Incoming Files
16:33:34,939 DEBUG [org.alfresco.repo.jscript.ScriptLogger] incoming 1 children: 2
16:33:34,939 DEBUG [org.alfresco.repo.jscript.RhinoScriptProcessor] Time to execute script: 101ms
16:33:34,939 INFO  [org.alfresco.web.scripts.DeclarativeWebScript] Caught exception & redirecting to status template: Failed to execute script 'D:\alfresco220dev\tomcat\webapps\alfresco\WEB-INF\classes\alfresco\extension\templates\webscripts\cayman\upload.post.js': Failed to execute script 'D:\alfresco220dev\tomcat\webapps\alfresco\WEB-INF\classes\alfresco\extension\templates\webscripts\cayman\upload.post.js': Wrapped java.lang.NullPointerException (AlfrescoScript#43)

The null pointer exception is at line 43, which is: logger.log("incoming 2 children: " + incoming2.children.length);

Accessing incoming.properties.children.length gives a null pointer exception in both cases (line 42), as does incoming.properties["cm:contains"].length.

This is all inside the upload.post.js script, which works fine except or this.

After deleting the whole repository (drop and create database, delete storage directory) the children property works again. Strange….
