"If an option is required, it is a static error to invoke the step without specifying a value for that option." Section 6.1 Static Errors defines the meaning of static error. "[Definition: A static error is one which can be detected before pipeline evaluation is even attempted.] Examples of static errors include cycles and incorrect specification of inputs and outputs. Static errors are fatal and must be detected before any steps are evaluated." Invocation of a step is typically something performed during evaluation. Therefore either this error should be a dynamic error, or it should be redefined to avoid use of "invoke", e.g. "If an option is required, it is a static error to specify the invocation of a step without specifying a value for that option." Test case "Test for err:XS0018 - 002" illustrates an example where this error condition can only be detected at run time - when options are not supplied when invoking the top-level pipeline. It is only when the host language fails to pass an option which is required that the invocation will fail. 83802 1 vojtech.toman 2013-02-27 14:14:54 +0000 Good observation. The simplest solution probably is to remove the test err-s0018-002 (and replace it with err-s0018-003). 84903 2 tim 2013-03-24 21:55:47 +0000 Having read the minutes of the WG teleconference, might I suggest adding new dynamic error codes to cover the case of (external) initiation of a pipeline, analogous to those in XSLT for initiating a transformation. 100869 3 ndw 2014-02-19 10:24:46 +0000 In 5.7.2 p:option, replace the first paragraph after the first p:option syntax diagram with: An option may be declared as required. If an option is required, it is an error to invoke that step without specifying a value for that option. For steps invoked within a pipeline, it is a static error (err:XS0018) to specify an invocation without specifying a value for a requried option. For pipelines invoked directly by an external environment (informally, top-level pipelines), this error cannot be detected statically. It is a dymamic error (err:XD????) to invoke a pipeline without specifying a value for a required option. 100870 4 tim 2014-02-19 10:26:22 +0000 Thanks.
