I mainly don't understand how to call this function:

QName.createQName("contracts.model", "metadata");‍

It seems on documentation that I need

createQName(java.lang.String prefix, java.lang.String localName, NamespacePrefixResolver prefixResolver)‍

but if I do this:

QName CUSTOM_ASPECT_QNAME = QName.createQName("contracts", "metadata", namespacePrefixResolver);‍

I get this error:

Caused by: java.lang.IllegalArgumentException: A Prefix Resolver must be specified‍

How do I use NamespacePrefixResolver??

any help?

You don't need to provider a namespacePrefixResolver.you got asked to provide a namespacePrefixResolver is because there is something wrong in your aspect namespace defintion .
You should define you aspect like this:


<?xml version="1.0" encoding="UTF-8"?>
<model name="contracts:contractsModel" xmlns="http://www.alfresco.org/model/dictionary/1.0">
   <description>Contract Metadata</description>
   <author>yangy</author>
   <version>1.0</version>
   <imports>
      <import uri="http://www.alfresco.org/model/dictionary/1.0" prefix="d"/>
      <import uri="http://www.alfresco.org/model/content/1.0" prefix="cm"/>
   </imports>
   <namespaces>
      <namespace uri="http://www.yourorganization.org/model/content/1.0" prefix="contracts"/>
   </namespaces>
   <aspects>
      <aspect name="contracts:metadata">
         <title>Contracts Metadata</title>
         <properties>
            <property name="contracts:masterID">
               <title>Master ID</title>
               <type>d:text</type>
            </property>
            <property name="contracts:companyName">
               <title>Company Name</title>
               <type>d:text</type>
            </property>
         </properties>
      </aspect>
   </aspects>
</model>

thanks but if I change the namespace URI, how would I reference contracts.model?

According to official Alfresco wiki here (http://wiki.alfresco.com/wiki/Data_Dictionary_Guide#Step_by_Step_Model_Definition) it is supposed to be just modelname.model?

Is the official Alfresco documentation wrong again?

Hi

I tried the suggested solution of changing the

<namespace uri="http://www.yourorganization.org/model/content/1.0"> ‍

and this is now the error:


Caused by: org.alfresco.service.namespace.NamespaceException: A namespace prefix is not registered for uri contracts.model
   at org.alfresco.service.namespace.QName.toPrefixString(QName.java:414)

Ok, so I have figured it out

This is the right URI for anyone having the same problem in the future:

 <namespace uri="http://www.yourorganization.org/model/yourmodelname/1.0" prefix="contracts"/> ‍
