Hi Simon, I just created a Jira to keep track of this issue: https://issues.apache.org/jira/browse/TUSCANY-2281
Besides using multiplicity="1..n", the interface Crawler is also Conversational. As mentioned in document "Java Common Annotations APIs", conversations are created when - a @Reference to a conversational service is injected - a call is made to CompositeContext.getServiceReference() and then a method of the service is called So the only way of having multiple conversations in parallel on the same Service from one client is to create multiple ServiceReferences. So if I use a injected reference, then I can not have multiple conversations on this reference. Or are there any other options to achieve this ? A workaround for my project could be - to use "Factory" classes for each Crawler. So in my client I could use a multiplicity reference to 1..n CrawlerFactories and in each CrawlerFactory a single 1..1 reference to a Crawler service. Then in the CrawlerFactory it would be possible to create ServiceReferences. - to simply don't use SCAs conversation mechanism but implement my own conversation handling. Any suggestions ?
