Kaleo Designer

With the proper permissions, users can publish assets. Even if your enterprise has the greatest employees in the world, many of the items they want to publish must still be reviewed, for a variety of reasons. The Kaleo Designer lets you design workflow definitions so your assets go through a review process before publication.

With Kaleo Designer, you develop workflow definitions using a convenient drag and drop user interface. You don’t need to be familiar with writing XML definitions by hand. Some of the features can be enhanced, however, if you’re familiar with Groovy, a supported Java-based scripting language. All that is to say, don’t be scared off when you come to a block of code in these articles. Just decide if you need the feature and find someone familiar with Java or Groovy to help you out.

Note: By default, only one workflow definition is installed: the Single Approver Workflow definition. What you might not know is that you have access to several others too. Look in [Liferay_Home]/osgi/portal/ and find the com.liferay.portal.workflow.kaleo.runtime.impl-[version].jar. Open it up and then look in META-INF/definitions. You’ll see the following workflow definitions:

category-specific-definition.xml
legal-marketing-definition.xml
single-approver-definition.xml
single-approver-definition-scripted-assignment.xml

To work with any of these definitions in Kaleo Designer, extract them from the JAR file first. Once you have the XML files locally,

1. Add a new workflow. Go to Control Panel → Configuration → Workflow, and click the Add button ().

2. Go to the Source tab.

3. Click import a file and upload the XML file.

4. Name the definition appropriately, and click either Save (to save it as a draft) or Publish (see below for more information on saving and publishing).

Now you can begin exploring or modifying the definition.

It’s time to start exploring the Kaleo Designer and its features.
