import a custom model inside another custom model to inherit

[dmralfing]

I´ve created in Alfreso two new custom models, father and child. I have to put in the XML child file that imports the model father, but I don´t know how I have to do it. For example if I inherit from cm:content, it´s very easy and typical, I put <import uri="http://www.alfresco.org/model/content/1.0" prefix="cm"/>. But if I inherit from a custom type, what should I have to put?. In the father namespace i put <namespace uri="aaa.bbb.father" prefix="fat">, so I though that I have to put in the child file <import uri="aaa.bbb.father" prefix="fat">, so I guess I´m wrong because it doesn´t works…
what I have to do??

Hi,

Your description looks fine, so for further insight
maybe you could provide some error message or exception trace from the logs?

Also make sure to first load the parent model. Sometimes you have to force it using a spring depends-on.

the parent model loads OK when I reboot, so I´m sure it´s right configurated
it says:
Caused by: org.alfresco.service.namespace.NamespaceException: URI aaa.bbb.father cannot be imported as it is not defined (with prefix fat
   at org.alfresco.repo.dictionary.CompiledModel.createLocalPrefixResolver(CompiledModel.java:203)
   at org.alfresco.repo.dictionary.CompiledModel.constructDefinitions(CompiledModel.java:128)
   at org.alfresco.repo.dictionary.CompiledModel.<init>(CompiledModel.java:88)
   … 48 more
I´m sure I´m referencing bad the father. I repeat: the father namespace is <namespace uri="aaa.bbb.father" prefix="fat">, and I import in the child writing exactly the same ULR: <import uri="aaa.bbb.father" prefix="fat">. I don´t know if is necesary to include a reference tothe father in the child-context.XML, but if I do it, it doesn´t works too.
  I only want to configurate an inheritance, it should be easy!!
Thanks

It looks like the parent model is not loaded before the child model and is therefore unknown.
Try to make the child model loading bean depends-on the parent model loading bean.

my working example:

<model name="ecm4uChild:ecm4uChildModel" xmlns="http://www.alfresco.org/model/dictionary/1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.alfresco.org/model/dictionary/1.0 modelSchema.xsd">
   <version>1.1</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"/>
      <import uri="http://ecm4u.de/model/parent/1.0" prefix="ecm4uParent"/>
   </imports>
   <namespaces>
      <namespace uri="http://ecm4u.de/model/child/1.1" prefix="ecm4uChild"/>
   </namespaces>
   <types>
      <type name="ecm4uChild:InfoDoc">
         <title>InfoDoc</title>
         <description/>
         <parent>cm:content</parent>
         <mandatory-aspects>
            <aspect>ecm4uParent:InfoAspect</aspect>
         </mandatory-aspects>
      </type>
   </types>

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

child dict-bootstrap bean depends-on parent bootstrap bean

<bean id="ecm4u.child" parent="dictionaryModelBootstrap" depends-on="ecm4u.parentBootstrap">
      <property name="models">
         <list>
            <value>ecm4uChildModel.xml</value>
         </list>
      </property>
   </bean>

I´ve resolved my problem, I did something bad in the context files, it´s so easy.
Thanks!

Details object is associated as child with parent type.Its working fine. You just need to define models in context file separately.
