SCXMLParser: Should the parser throw an exception on a parsing error?
---------------------------------------------------------------------
Key: SCXML-80
URL: https://issues.apache.org/jira/browse/SCXML-80
Project: Commons SCXML
Issue Type: Improvement
Affects Versions: 0.8
Reporter: Ingmar Kliche
I noticed that the SCXMLParser::DigestSrcAttributeRule() function only logs a
message (and returns to continue parsing at next element) in case there is
trouble in resolving the src-Attribute (i.e. to source in content from other
SCXML documents). The particular use case is a wrong fraction of the
src-Attribute of the <state> tag, i.e. if the state which was refered to using
the url fraction does not exist in the target document.
Thus when using the parser it is not possible to know whether the parsing was
actually successful. In the above given use case the parser returns a valid -
but incomplete - statemachine. And this is a severe problem.
Hence, shouldn't the parsing error bubble up, e.g. using an exception?
