Passing Database Server To Digital Metaphors Report Builder Server

Question

I'm using Report Builder (Server) to run my reports. We currently host the component in a windows service, now the web tier we have is passing some information through to the server, the usual stuff like the report to run etc, but also the database server on which to run the report.

We seem to be able to pick up these properties in the data component but halfway through the processing the server seems to delete the data component and create a new one without re-calling any of the events. This means that all the data connections on the component revert to their designer set connection strings rather than the ones passed in.

Is there any way to get these settings pulled through.
