Property decorators with dynamic models

cgiuliano — Tue, 11 Feb 2014 13:17:34 GMT

Hi everybody,I'm in the middle of testing dynamic model deployment, that sounds to be very easy for fast changes during the design and development phases!I've found an issue about property decorators: I cannot add my decorated property to the list of category decorators, just because I don't know wh

Hello,

there is currently no support for dynamic Spring configuration in Alfresco (except what is possible using subsystems).
You might want to check if <a href="https://addons.alfresco.com/addons/dynamic-extensions-alfresco">the Dynamic Extensions addon</a> can help you here. That would be the only potential way to go that I know of.

Hi Axel,
That extension sounds interesting.

Actually I've worked the issue around by defining a minimal model in the file system (including just the namespace and the property to be decorated) and then extending it to the full model by uploading the full definition into the Data Dictionary.
I know it is a very unclean approach…, although it seems to be effective.

I'll have a look at the extension you mentioned.

Thanks a lot!

Carlo

Or you can bypass namespace check by implementing your own category property decorator.
You can do it like this
1. copy org.alfresco.repo.jscript.app.CategoryPropertyDecorator and rename it(for example MyCategoryPropertyDecorator)
2.override setPropertyName method like following


    @Override
    public void setPropertyName(String propertyName)
    {
        propertyNames = new HashSet<QName>(1);        
        propertyNames.add(QName.createQName(propertyName));
    }
‍‍‍‍‍‍‍‍

3.config your MyCategoryPropertyDecorator in spring file.


<bean id="my.categoryPropertyDecorator" parent="categoryPropertyDecorator" class="**.MyCategoryPropertyDecorator" >
   <property name="propertyName" value="{http://www.example.org/model/content/1.0}category" />    
</bean>
‍‍‍‍‍

But This is not an ideal solution.

Kaynezhang,
thanks a lot for your suggestion.

If I got it well, it will perfectly run as long as I don't use the namespace prefix for the decorated property, won't it?
That sounds good!

Thank you,
Carlo

The default implementation 's setPropertyName method's defination is like following(defined in setPropertyName.BasePropertyDecorator)


   public void setPropertyName(String propertyName)
    {
        propertyNames = new HashSet<QName>(1);        
        propertyNames.add(QName.createQName(propertyName, namespaceService));
    }
‍‍‍‍‍‍‍

QName.createQName(propertyName, namespaceService) will call namespaceService to check and calculate namespace URI.

after override this method like following


    @Override

    public void setPropertyName(String propertyName)

    {

        propertyNames = new HashSet<QName>(1);        

        propertyNames.add(QName.createQName(propertyName));

    }
<bean id="my.categoryPropertyDecorator" parent="categoryPropertyDecorator" class="**.MyCategoryPropertyDecorator" >

   <property name="propertyName" value="{http://www.example.org/model/content/1.0}category" />    

</bean>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

you will provide namespace URI directly to property decorator and bypass namespace URI check.
