Subject: Re: [wsbpel] Issue 103 - How to write a propertyAlias for a messageType?
Hi, How do we write a propertyAlias for a messageType? Now that we have passed the proposal for Issue 103 with $var.part (or $var_part) amendment, a property alias query can not contain anything to specify a part. Probably we need something here to fix the problem. Below are some ideas: A. Introduce a special variable "source" (or other proper name.). Bind $source to the data from which the property value is derived. Eg. <propertyAlias propertyName="a:prop" messageType="b:msgTyp"> <query> $source.part1/some/element/here </query> </propertyAlias> B. Add messagePart attribute to propertyAlias element. Eg. <propertyAlias propertyName="a:prop" messageType="b:msgTyp" messagePart="part1"> <query> /some/element/here </query> </propertyAlias> (Must a query start with "/"?) With B, query can be applied only to one part. With A, you can write something like concat($source.part1/some/element, $source.part2/another). I prefer A. Yuzo Fujishima NEC Corporation
