3.2.2.4. Validation

Argument Validation

• RequiredArgument

If the InArgument is a required argument and no data is filled, a validation error will appear in the Workflow Designer panel.

• Property Validation

Validation is made upon the property value, whether is not null or empty. If it is empty, a validation error is thrown.

Another example is when an undeclared variable or argument is used on a certain parameter. A validation error is thrown.


Runtime Validation
If the execution of the workflow / snippet is started and there are validation warnings and errors, when click on Start button, an Error window opens warning the user about the error .
