When you validate a model or modeling diagram, errors
and warning messages are displayed in the Problems view.
You can navigate directly to the violation in the Model
Explorer view, which is helpful when a model is large
and contains many model elements.
There are three levels of model validation
severity:
- An error is a critical violation that is not
allowed.
- A warning is less severe than an error; it indicates a rule
violation that is allowed, but that results in your model being
semantically incorrect.
- An informational message is the least severe form of violation;
it indicates a rule that is inconsistent with Unified Modeling Language
(UML) standards but that does not need to be corrected.
You
must have validated a model or modeling diagram.
To view the subject of a validation error or warning,
in the Problems view, right-click an error
or warning; then click Go To.
The involved model elements are selected in the Model
Explorer view.
Note: The list of validation
errors is also displayed in the Alerts and Action Items section
of the UML Model Editor.
After you view the validation errors and warnings, you
can repair them.
