Subject: RE: [wsbpel] Issue - 123 - Matching <reply> with <receive>


Hello Yuzo,

the problem with giving two receives the same MEP (or the same id) is, that it is hard/impossible to statically analyse the situation, and decide if it is a valid usage of reply. With the unique solution, one can be a bit more safe.

Of course there  are more runtime errors which can happen, so it might not be too interesting to avoid this particular. However, I am not sure if the case of different receives with a single reply is very common.

One possible option to MEP elements would be to have the variable holding the received message to have a special meaning, so you can "reply" to the request variable. That would be essentially the MEP name, without the need for a new construct. However it would require some variables to be "special".

Mit freundlichen Grüßen
