5.2. Workflow patterns
Workflow patterns are predefined blocks of Process elements that allow you to reuse once defined combination of Process elements: they include multiple nodes that are connected and form a common executable pattern that can be reused in a Process model.
Workflow patterns are available in the Shape Repository stencil set and can be drag-and-dropped on the canvas just like any other elements. To attach a pattern to an element on the canvas, select the element and then drag-and-drop the pattern from the palette onto the canvas. The pattern will be automatically connected to the element.
Multiple predefined workflow patterns are provided by default and you can define your own workflow patters as necessary. The definitions are defined as JSON objects in the
$JBOSS_HOME/standalone/deployments/business-central.war/org.kie.workbench.KIEWebapp/defaults/patterns.json file.
5.2.1. Defining workflow patterns
To define custom workflow patterns, do the following:
- In the stencil set of the Process Designer, locate the workflow pattern that resembles most to and that will use as base for your workflow pattern.
- Open the
$JBOSS_HOME/standalone/deployments/business-central.war/org.kie.workbench.KIEWebapp/defaults /patterns.jsonfile in a text editor. - Locate the JSON object with the description property set to the base workflow pattern name (for example,
"description" : "Sequence Pattern"). - Copy the JSON object and modify its elements as needed. Note that all the JSON objects are nested in a pair of square brackets and are comma separated.
