Specifications

it is not strictly true for all data types; for example a file path becomes invalid when the target
file is removed.
Properties that contain a variable or a script expression are validated while the flow is running,
since their value cannot be determined at design time. Just before each invocation of the
jobArrived entry point, Switch performs run-time validation for all properties of the flow element
that contain a variable or a script expression. If a property value is invalid, Switch fails the job
with an appropriate error message.
Note that there is NO run-time validation before calling the timerFired entry point (or any of the
other entry points). Using non-static property values from those entry points is risky anyway
since there is no job context (and referencing job context from a script expression or variable in
those circumstances has undefined results).
Validation at design time
Validation of a particular property value is performed at design time if isPropertyValueStatic()
returns true for that property.
The following table describes the standard design-time validation for values entered by a
particular property editor. Note that all property values are of data type string or string list.
