Enabling workflow

Liferay’s Kaleo workflow engine can be installed for both CE and EE versions of Liferay. The web plugin’s name is kaleo-web and is bundled in the Kaleo Forms EE and Kaleo Workflow CE apps on Liferay marketplace. Installing the plugin adds a number of new options to the control panel:

• My Workflow Tasks

• Workflow Configuration

• My Submissions

• Workflow

There is one workflow that comes bundled with the kaleo-web plugin: Single Approver Workflow. This workflow requires one approval before an asset can be published. One of the conveniences of using Liferay’s workflow engine is that any roles specified in the workflow definition are created automatically when the definition is deployed. This provides a level of integration with the portal that third party engines cannot match. The Single Approver Workflow contains three roles each with different scopes. The scope of each role can be deduced by their names: Site Content Reviewer, Organization Content Reviewer and Portal Content Reviewer.

Let’s jump right in and create a workflow process definition.
