Subject: Re: [wsbpel] Issue - 131 - revisiting section 9.3.1 "Type Compatibilityin Assignment"



Memory overflow here ... :-)
Yup,  Yaron, you are right. After re-reading the description of Issue 51 
emails, Issue 131 would be a duplication of Issue 51.

Peter, could you please close this issue as a duplication of Issue 51. 
Sorry for creating this manual work for you.


Regards,
Alex Yiu
