Re: [bpel-dev] Xpath or BPEL validation error? 
hi Bryan
I also got many this kink of errors too, actually, there are much more bugs in validator than you list below, I have worked on a project that based on the Eclipse BPEL project for a long time, and have some patches for the BPEL Validator issues includes the bugs you list, I would like to report the bugs to Eclipse BPEL bugzilla and attach the patches, if some guys of BPEL team could take a look at it and apply it, it would be great ;) I hope I can help you a little bit if you would like to get any help of the validator.

Hi All,
I've been following the Eclipse BPEL Editor for quite some time. Since my project is finally moving from BPEL 1.1 to 2.0 with the ODE engine I can now begin to make use of, and hopefully contribute to, this tool and community.
I followed the tutorial hosted here (Thanks babelfish): http://babelfish.yahoo.com/translate_url?doit=done&tt=url&intl=1&fr=bf-home&trurl=http%3A%2F%2Fwww.se.uni-hannover.de%2Flehre%2Ftutorials%2FBPEL-ODE-Eclipse-Getting-Started.php&lp=de_en&btnTrUrl=Translate> <http://> 

Using Eclipse 3.4.2 J2EE distribution and the latest source from CVS.
The editor reports 3 errors and 1 info in the BPEL source generated by the addition of the Assign step. 


        <bpel:assign validate="yes" name="Assign">
<bpel:copy> -- Copy rule not checked - from-spec type-of "unspecified", to-spec type-of "<complexType>". 
                <bpel:from>
<tns:result></tns:result> 
</tns:HelloWorldResponse>
</bpel:literal>
                </bpel:from>
                <bpel:to part="payload" variable="output"></bpel:to>
            </bpel:copy>
<bpel:copy> -- The from-spec of "<complexType>" is not compatible with to-spec of "<complexType>" 
                <bpel:from part="payload" variable="input">
<bpel:query queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0"> <![CDATA[tns:input]]> -- XPath expression "tns:input" in <tns:input> is not a LocationPath expression. 
                    </bpel:query>
                </bpel:from>
                <bpel:to part="payload" variable="output">
<bpel:query queryLanguage="urn:oasis:names:tc:wsbpel:2.0:sublang:xpath1.0"> <![CDATA[tns:result]]> -- XPath expression "tns:result" in <tns:result> is not a LocationPath expression. 
                    </bpel:query>
                </bpel:to>
            </bpel:copy>
        </bpel:assign>
I am able to successfully deploy the HelloWorld process to ODE and it runs successfully without error. So this leads me to believe there is a bug in the validation, not the code generation. I cannot tell if the "from - to spec not compatible" error is a byproduct of the LocationPath expression errors or not. I would love to help provide a fix here to get my feet wet but I'd like a little help determining what's going on and where I might look in the code. 

Thanks!
