judo-runtime:validation-rules

JUDO validation can pass unexpectedly if the validation context skips invalid values or bypasses required fields. Inspect metamodel constraints and enable DEBUG logging on the judo-validator package to verify the exact flow.

Debug nested validation errors in JUDO by inspecting the validation results object and checking traversal depth settings in your validation context. Use metamodel inspection to verify constraints are applied correctly to nested attributes.

JUDO provides built-in validators like PatternValidator for regex enforcement, and validators for maxLength and precision constraints. These enforce metamodel rules on data payloads during the validation flow.

Configure the JUDO validation context to control traversal depth, required field validation, and invalid value skipping. These context options determine how strictly the validation flow enforces constraints on nested data structures.

Precision validation failures in JUDO occur when data values exceed the precision constraint defined in the metamodel. Inspect the attribute's precision settings and verify the input data matches the expected decimal scale.
