Alfresco: Property Decorators — cont.
In my post on Property Decorators I pointed out that there was an issue adding a customer property decorator: you couldn’t create a custom bean to perform the mapping and had to overwrite the out of the box bean. Well Mike Hatfield has found a solution which is just awesome: Map Merge.
It is possible to merge maps of a child bean to a parent bean. Here is how it is done: Create a new bean, where the parent is the
applicationScriptUtils bean. Add a single property of
decoratedProperties and define a map in the property. When you define the map add the attribute
merge="true". Finally, add your custom property to decorator bean mappings. Done!
Here is an example:
<bean id="customApplicationScriptUtils" parent="applicationScriptUtils"> <property name="decoratedProperties"> <map merge="true"> <entry key="alf:propertyHolder"> <ref bean="customDecoratorBean"/> </entry> </map> </property> </bean>
