Expression Editor

The expression editor is a productivity tool that can be used to create expressions when defining the logic in the DMN Expression window.  This diagram shows a simple model with a decision with an expression type of Boxed Context that uses a Business Knowledge Model element. We will look at how we can use the intellinsense otherwise knows as a code completion to

The expression Editor dialog is used for setting expressions in the Boxed content, Invocation and Literal Expression element types. It provides Intelli-sense support for constructing expressions based on the FEEL grammar, as well as the code languages that can be used for the code generation of the model.

This diagram shows the multi-purpose Expression window that is used to define the input data that, as you will see from the diagram, provides input data for the Application Risk Score decision. We will see in the next few steps how Enterprise Architect makes these data items available to the expression editor through intelli-sense. The next illustration shows how to launch the Expression Editor.

With the editor open, the modeler detailing the expression and logic can utilize this productivity tool and reduce the logic errors by accessing the data items with intelli-sense that makes the input data available in a list.
