[xwiki-users] Accessing nested document in velocity

Hi guys, I'm having a hard time accessing the fields of an application (prepared via App Within Minutes) document from another document. I have those 2 documents: 1. XApp / Data / 123456789 2. Test / Testscript I try to prepare an event listener to rename new documents according to some of their fields. For example I have the field 'ddlCategory' and I want the name of all new documents of the XApp application to be "XP-<category>-DateTime". To get the doc before accessing the objects of the class I tested retrieving XApp.WebHome: #set($docRef = $services.model.createDocumentReference('', 'XApp', 'WebHome')) #set($document = $xwiki.getDocument($docRef)) "$document.getContent()" shows me the content. Now I want to get the nested Data space (where the documents are stored and which contains the livetable): #set($docRef = $services.model.createDocumentReference('', 'XApp.Data', 'WebHome')) #set($document = $xwiki.getDocument($docRef)) "$document.getContent()" is not replaced, the resulting page shows "$document.getContent()" so it can't find the XApp.Data.WebHome. In the reference I tried different things (ie "Xapp\.Data") but it also fails. So how to retrieve a nested document in velocity? Thanks in advance, Dennis
