New Alfresco tutorial on implementing custom behaviors
I’ve written a follow-on article to “Alfresco Developer: Working with Custom Types”. This one is on implementing custom behavior. In the new article (with accompanying source code), I build on the SomeCo Whitepapers example by adding support to the content model for user-contributed ratings of whitepapers. The custom behavior is used to calculate the average rating for each piece of rated content.
My plan is to follow on shortly with an article that shows how to use Alfresco’s new REST-based Web Script framework to enable the front-end to rate (and get the rating of) content in the Alfresco repository.
So take a look and let me know what you think.
More about the Alfresco Developer Series.
[...] Jeff Potts from Optaros has published another excellent tutorial, this time on adding custom behaviors to Alfresco to support “rating/scoring” of content. [...]

Hi Jeff,
Thanks a lot for such great article.
I like to have useful samples of Alfresco usage and customization.
I would ask you how the performance of the rating sample would be improve, if the sc:rateable aspect stores the current sum and count of existing sc:ratings children ?
The computeAverage() method won’t have to rescan all the children and will update the rating more efficiently.
Hope to see your next article soon
Cordialement,
David

@David…Agreed. Storing the sum and count as well as the average as part of the aspect would be an improvement. Thanks for the feedback. Glad the article was valuable.

@Luis — I’m glad you have found it valuable. I’m hoping to post it by the end of this week. After that, I’m thinking of doing one on advanced workflow with JBPM but I’m open to suggestions.

[...] Alfresco behaviors can be very useful when you need to perform some system-level action as part of an operation on a node. For example, let’s say whenever an instance of my custom type is created, I want to generate a unique id value and record it in a custom attribute on the new node. I can register a behavior that handles the onCreateNode event, bind it to my custom type, and then I can provide a simple Java method to do the work of generating the id value and setting the property. If you’re new to behaviors, Jeff Potts provides an in-depth discussion and tutorial. [...]

Hello Jeff and thanks for that wonderful tutorial!
I’m trying to implement the javascript one. Since you stated “In this example the scripts are going to reside as part of the web application rather than being uploaded
to the repository. Nothing requires that this be the case” I tried to remake it with the scripts in the repository.
I guess I have to modify the “location” property but I couldn’t find how. Do I have to write my own java class extending org.alfresco.service.cmr.repository.ScriptLocation ?
