client side vs server side deliver pre-condition advice
I have a question about client side vs server side deliver pre-condition, that a customer asked and I want to confirm that my understanding is correct.
My customer wants to implement a control on new files being created. The work occurs in the RTC client. 1/ Is there a way now to trigger processing at check-in ? That would be the best place to do it, so that the control would be performed as early as possible. 2/ the control that the customer wants to do might be expensive in some cases. I understand that precondition running on the server side run in the context of a transaction. Delaying the commit of the transaction is not good for other transactions. In this case, is it safer to run this control as a client-side deliver pre-condition (if check-in is not available) ? Thanks, Nicolas |

Hi Nicolas,
as far as I know there is no extension point for check in. I have no solution to that. You would maybe want to make sure that not more than on file goes into a change set and I think you can't. All you could do is check that at deliver. In general you want to have server based operational behavior, rather than client side, because it is much easier to deploy and maintain (only on the server). Client side behavior is only needed if the information it acts on is only available on the client. E.g. a syntax checking program or something like that. I don't think you gain anything in the transaction department, since the transaction spans the client as well as the server. Comments

Custom client side operational behavior only works in the Eclipse based clients. We don't have a way to extend the other clients. So you would have to make sure it is installed everywhere and fails if not.
Thanks Ralph for the answers.
The whole point of a pre condition/advisor is to be able to prevent the transaction from finishing. I don't know all the glory details, but if the advisor fails, the transaction is not performed. Again, a pre-condition is to control behavior and not to change the data of the item.
