Subject: Re: [wsbpel] Issue - 32 - Link Semantics in Event Handlers
Yuzo, in the specified example, each message creates a new instance of the flow activity. Whenever a message arives, an instance of the appropriate OnMessage event handler is created and the enclosed activities are carried out. There are no restrictions on the number of created instances for event handlers nor are there any restrictions for the number of created instances for a particular OnMessage event handler.

The problem is that the specification itself allows at least two interpretations. I raised this issue to clarify which is the right one. After the discussion and the issue/requirementprocess mature, I probably propose a motion to pick one iterpretation.
