Method Details

getProblem

public Problem getProblem()

Extends the default behaviour of getProblem to return either the problem the error was created with, or will concoct one from the message the exception was created with. This is a half-way house - ultimately all the binding code should be changed to use problems and i18n instead of anonymous messages in exceptions, but this at least allows code to start using ParameterBindingException.getProblem instead of getMessage

Overrides:

getProblem in class RiskscapeException

Returns:

the problem associated with this exception, or null if there is none

getModelParameter

public Parameter getModelParameter()
