If there are no more pending it starts the installed deployments<br/><span style="color: #204a87; font-size: 10pt; ">(12:40:15 AM) </span>tdiesler: yes, if I had access to the notion of DeploymentSet I could associate lifecycle with the set<br/><span style="color: #204a87; font-size: 10pt; ">(12:41:29 AM) </span>tdiesler: some other form of SetContext.start/SetContext.end would also do<br/><span style="color: #cc0000; font-size: 10pt; ">(12:42:48 AM) </span>bstansberry: I'll think about how the DeploymentSet could be managed. The ServerDeploymentManager knows there is a plan, so could associate a DeploymentSet with each individual update.<br/><span style="color: #cc0000; font-size: 10pt; ">(12:43:00 AM) </span>bstansberry: and the set could be attached to the DeploymentUnitContext<br/><span style="color: #204a87; font-size: 10pt; ">(12:43:09 AM) </span>tdiesler: right on<br/><span style="color: #cc0000; font-size: 10pt; ">(12:44:00 AM) </span>bstansberry: but something would need to trigger the fact that all the updates in the set have been processed<br/><span style="color: #204a87; font-size: 10pt; ">(12:44:06 AM) </span>tdiesler: I would need to be able to associate state with the set<br/><span style="color: #204a87; font-size: 10pt; ">(12:44:15 AM) </span>tdiesler: perhaps attach stuff to it<br/><span style="color: #cc0000; font-size: 10pt; ">(12:44:17 AM) </span>bstansberry: ok<br/><span style="color: #204a87; font-size: 10pt; ">(12:45:12 AM) </span>tdiesler: callback on the set?<br/><span style="color: #cc0000; font-size: 10pt; ">(12:45:44 AM) </span>bstansberry: yeah<br/><span style="color: #204a87; font-size: 10pt; ">(12:45:57 AM) </span>tdiesler: merci (f)</p></div>
