Field Detail

PROPAGATION_LIMIT_KEY

public static final java.lang.String PROPAGATION_LIMIT_KEY

Key of a context value specifying a limit for the number of problems propagated up the view model hierarchy from any given control. Values are either a positive Integer for a propagation limit or "*" for unlimited propagation. The default is unlimited propagation, so the use cases for the "*" value should be few in number.

If this value is to be injected into the context by a client application, it is recommended to do so via the factory APIs that accept an initial map of context values, for example, ViewModelContextFactory.createViewModelContext(VElement, EObject, Map). For applications that are not in control of the editor's context lifecycle, an alternative approach is to set context values in the initialization of a global ViewModelService registered at a priority less than the ValidationService priority (which by default is 1.0. This ensures that the service setting the context value is initialized before the validation service, so that the context value can be put before the validation service picks it up.
