Inline variable initialization in Ode 1.3.2
Hello again. I have a question about using the inline from-spec for
variable initialization
(http://cwiki.apache.org/confluence/display/ODExSITE/WS-BPEL+2.0+Specifi
cation+Compliance#WS-BPEL2.0SpecificationCompliance-Initialization).
It's not working for me and I was hoping someone could tell me if I'm
doing something wrong. Here is a very simple example in which I try to
assign data to and from a variable that has an inline initializer. I
get a selectionFailure at runtime.
--------------- Begin TestInlineInitialization.wsdl ---------------

According to http://issues.apache.org/jira/browse/ODE-236 it looks like
this has only been fixed on the 2.0 version.

RE: Inline variable initialization in Ode 1.3.2
Posted by Jonathan Coogan <Jo...@Attachmate.com>.
Hi Bill. I remember reading that at some point in the past. I thought
that inline initialization was a new feature in Ode 1.3 but maybe it
wasn't added after all.
The compliance page needs to be updated in either case. I guess the
question now is whether inline initialization is supposed to work in
1.3.2.
Thanks.

Hi Jonathan,
An interesting bit was pointed out to me on the specification
compliance page
(http://ode.apache.org/ws-bpel-20-specification-compliance.html). It may
just be old information but under <assign> activity there is a line
stating "Inline assignment as part of the variable declaration isn't
currently supported." I recall that at some point in time it was not
supported but it would be nice to get this clarified: should inline

Hi Jonathan,
An interesting bit was pointed out to me on the specification
compliance page
(http://ode.apache.org/ws-bpel-20-specification-compliance.html). It may
just be old information but under <assign> activity there is a line
stating "Inline assignment as part of the variable declaration isn't
currently supported." I recall that at some point in time it was not
supported but it would be nice to get this clarified: should inline
initialization work?

RE: Inline variable initialization in Ode 1.3.2
Posted by Jonathan Coogan <Jo...@Attachmate.com>.
Hi Bill. Good suggestion. Even when I echo the inline initialized
variable back to the response it does not work. I created a simpler
example that uses an initialized variable of type string. When I assign
to to the response I get an AssignmentFault saying that the variable is
uninitialized.

Hi Jonathan,
The inline initialization looks fine in regard to the spec. A
selectionFailure could also come from a problem with the query used in
the assign. If you just echo the inline initialized variable back to the
response does the expected structure get returned? If so then the
problem is the query used in the assign.
