FEEL Engine Legacy Behavior
If you come from a Operaton version $\leq$ 7.12.x and already use FEEL, it might be that you need to migrate your DMN models. To do this, please check out the [Migration Guide], where we've documented all breaking changes.
If you don't want to migrate your DMN models right now, you can also restore the legacy FEEL behavior by flipping a config flag:
- To see how this legacy behavior can be enabled again in Operaton, please see the dmnFeelEnableLegacyBehavior engine configuration property.
- To enable this behavior in a standalone DMN Engine setup, please refer to the
DefaultDmnEngineConfigurationenableFeelLegacyBehavior and [setEnableFeelLegacyBehavior][feel flag setter] methods
Heads Up!
By using the legacy FEEL Engine, the Operaton DMN Engine only supports FEEL for
Input Entries of a decision table – this corresponds to FEEL
simple unary tests.
