Subject [jira] Commented: (AXIS2-632) get errors trying to parse valid response

Chuck Williams commented on AXIS2-632:
--------------------------------------

Ajith,

It seems just about everybody agrees that xsi:type is a feature request, and certainly not
a blocker, so I agree with your proposal.

Did you notice the whitespace issue buried in the discussion and patched in the attachment?
 I think that is an important bug fix for 1.0.

Simon noted on the mail list:  "If ADB doesn't support extension, that it should flag this
during the WSDL2Java stage, and not throw cryptic errors at runtime."  However, it appears
ADB does support extension and compiles code for the extension types correctly.  The issue
is that it does not support xsi:type at runtime.  We could add a check for xsi:type in the
attribute parsing code and throw a more meaningful exception there rather than dying when
the base type parser sees properties only on the subtype.  However, I would not deem this
an essential fix for 1.0, as there are likely other constructions that are similarly not handled
and not detected.
