            Description

            When adding the mapping between the property and the decorator bean, it can only be added to the OTB applicationScriptUtils bean. Adding custom beans breaks Alfresco (ie the custom bean overwrites the OTB bean).

                jottley Jared Ottley added a comment -

                Addition background:

                I'm adding a decorator to pass back if the current user has synced the node to dropbox or not (maintained in an association to a node with the specific dropbox metadata for the current user).

                I've added a custom property to my model

                <property name="db:isSyncedToDropbox">
                <type>d:boolean</type>
                <default>false</default>
                <index enabled="false"/>
                </property>

                I've defined a class to decorate the property

                @Override
                public Serializable decorate(NodeRef nodeRef, String propertyName, Serializable value)

                { Map<String, Serializable> map = new LinkedHashMap<String, Serializable>(4); boolean synced = dropboxService.isSynced(nodeRef); map.put("userIsSyncedToDropbox", synced); return (Serializable)map; }

                And I've added the bean to context file

                <bean id="syncedToDropbox" class="org.alfresco.dropbox.repo.jscript.app.SyncedToDropbox">
                <property name="dropboxService">
                <ref bean="dropboxService"/>
                </property>
                </bean>

                The last thing to do is map the customer decorator bean to the model property

                If you define your own custom instance of the bean to do the mapping, you get the exception thrown

                <bean id="dropboxApplicationScriptUtils" parent="baseJavaScriptExtension" class="org.alfresco.repo.jscript.ApplicationScriptUtils">
                <property name="decoratedProperties">
                <map>
                <entry key="db:isSyncedToDropbox">
                <ref bean="syncedToDropbox"/>
                </entry>
                </map>
                </property>
                </bean>

                So the only option is to overwrite the OTB bean definition in script-services-context.xml

                <bean id="applicationScriptUtils" parent="baseJavaScriptExtension" class="org.alfresco.repo.jscript.ApplicationScriptUtils">
                <property name="extensionName">
                <value>appUtils</value>
                </property>
                <property name="serviceRegistry">
                <ref bean="ServiceRegistry"/>
                </property>
                <property name="decoratedProperties">
                <map>
                <entry key="cm:creator">
                <ref bean="usernamePropertyDecorator"/>
                </entry>
                <entry key="cm:modifier">
                <ref bean="usernamePropertyDecorator"/>

                <entry key="cm:workingCopyOwner">
                <ref bean="usernamePropertyDecorator"/>
                </entry>
                <entry key="cm:lockOwner">
                <ref bean="usernamePropertyDecorator"/>
                </entry>

                <entry key="cm:taggable">
                <ref bean="tagPropertyDecorator"/>
                </entry>
                <entry key="cm:categories">
                <ref bean="categoryPropertyDecorator"/>

                </entry>
                </map>
                </property>
                <property name="userPermissions">
                <list>
                <value>CancelCheckOut</value>
                <value>ChangePermissions</value>
                <value>CreateChildren</value>
                <value>Delete</value>
                <value>Write</value>
                </list>
                </property>
                </bean>

                Now everything is copacetic.

                Following Mike Hatfield's suggestion we have something that works: map merging the decoratedProperties.

                Example:

                <bean id="dropboxApplicationScriptUtils" parent="applicationScriptUtils">
                <property name="decoratedProperties">
                <map merge="true">
                <entry key="db:isSyncedToDropbox">
                <ref bean="syncedToDropbox"/>
                </entry>
                </map>
                </property>
                </bean>

                So in short create a custom bean where the parent is the applicationScriptUtils bean. Add a single property: decoratedProperties. In the map tag add the attribute merge="true". Add the entries you want merged to the OTB decoratedProperties property map.
