[ http://issues.apache.org/jira/browse/JAXME-47?page=comments#action_57622 ] Jochen Wiedmann commented on JAXME-47: --------------------------------------
This is how a union converts a string at runtime: For any possible type, in the order specified by the schema, it attempts to convert the string into the requested type. If no exception occurs, then the result is taken. If an exception occurs, then the next possible type is attempted. Finally, an exception is thrown, if no type was successfull. The UnionTypeSG does this, by invoking all the types in order and let them create code. The returned code is surrounded with exception handlers. In other words, the right thing to do for default values is as follows: The UntionTypeSG should invoke the internal SG's in order and let them convert the string. The result of the first one, that produces no error, is taken. If they all throw errors, then the value is invalid. > When using default values initialization of vars doesn't work for all types > --------------------------------------------------------------------------- > > Key: JAXME-47 > URL: http://issues.apache.org/jira/browse/JAXME-47 > Project: JaxMe > Type: Bug > Components: JaxMe Core > Reporter: Nacho G.
