AMP/AMP model dependency

[stephenl]

Hi,

I'm just wondering if there's a way to have two AMPs and have a custom model in one dependent on a custom model in another? Using Eclipse I have previously built my root amp and have it sat in a dependency folder when I build and deploy my child AMP:

 <build>
        <plugins>
            <plugin>
          <groupId>org.alfresco.maven.plugin</groupId>
          <artifactId>alfresco-maven-plugin</artifactId>
          
          <extensions>true</extensions>
          <executions>
             <execution>
               <id>install-amps</id>
               <goals>
                   <goal>install</goal>
               </goals>
               <phase>package</phase>
             </execution>
          </executions>
          <configuration>
            <ampLocation>libs</ampLocation>
          </configuration>
        </plugin>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

This all seems to work fine for the availability of the webscripts in the root AMP (at run-time) but not for referring to the root model even though it is declared as imported in the child model:

<imports>
  <!– Import Alfresco Dictionary Definitions –>
  <import uri="http://www.alfresco.org/model/dictionary/1.0" prefix="d" />
  <!– Import Alfresco Content Domain Model Definitions –>
  <import uri="http://www.alfresco.org/model/content/1.0" prefix="cm" />
  
 <import uri="http://someurl/othercomponent/content/1.0" prefix="rootmodel" /> 
 </imports>
‍‍‍‍‍‍‍‍‍‍

But I always get errors stating that rootmodel cannot be found.

Edit:Basically, what I'm aiming for is the ability to derive a child custom content type from one defined in the root AMP's custom content model.


Thanks a lot.

Hi,

Sounds like you're just having problems controlling the order that your amps are being loaded by the system at startup.  The module.properies file has an available option called module.depends.* which allows you to specify that your module depends on (a particular version/minimum version/version range of) another amp.

E.g. module.depends.RootAmp.1.0.0

Have a look at http://docs.alfresco.com/5.1/concepts/dev-extensions-modules-module-properties.html for some examples of what you can do.

Hi Steven,

Thank you for a detailed answer, I was unaware of the module.properties file contents and I have added in the dependency as you suggest. Although I don't think this immediately solved the problem it will still be required as the child amp will require the root project to be in place. Ultimately I had to modify {project.id}-model-context.xml in the extension folder of my child project to be dependent on the root project:

<!– Registration of new models –>
   <bean id="child.dictionaryBootstrap" parent="dictionaryModelBootstrap" depends-on="root.dictionaryBootstrap">
      <property name="models">
         <list>
            <value>alfresco/extension/model/childModel.xml</value>
         </list>
      </property>
   </bean>
‍‍‍‍‍‍‍‍‍‍

The depends-on="root.dictionaryBootstrap" seems to have solved it but module.properties still needs modifying to ensure the root's existence.

Thanks,
Stephen
