Subject: RE: [wsbpel] Issue - 111 - Proposal For Vote
Hi Danny, You could write it that way but if your readers are setup to find them at the activity layer like sources and targets then they wouldn't find them. Plus it will be inconsistent for example: <flow> <links><link name="l1"></links> <receive ...> <target linkName="l1"/> </receive> <receive ...> <target linkName="l1"/> <ns1:assert>...expression...</ns1:assert> </receive> <extensionActivityWrapper> <source linkName="l1"/> <ns2:call process="ns:name"> <ns1:assert>...expression...</ns1:assert> <ns2:call/> </extensionActivityWrapper> </flow> Notice how standard elements will be with the wrapper but my extended standard elements are not. - Chris -----Original Message----- From: Danny van der Rijn [mailto:dannyv@tibco.com] Sent: Friday, July 22, 2005 1:27 PM To: chris.keller@active-endpoints.com Cc: 'Francisco Curbera'; 'wsbpeltc' Subject: Re: [wsbpel] Issue - 111 - Proposal For Vote In Paco's proposal, you would simply write that: <extensionActivityWrapper> <ns2:call process="ns:name"> <ns1:assert>...expression...</ns1:assert> <ns2:call/> </extensionActivityWrapper> Chris Keller wrote: >Hi Paco, > >I still have the one issue I mentioned in the last meeting.
