We are currently planning to extend our solution with typical maitenance workflows.
Today we have a registration workflow in place for a specific business entity, and now we need to control the change management process for this entity.
What is the best practice for launching such workflows with K2.NET and InfoPath forms? With webforms we could easily called upon a SmartForm and passed a entity ID as a querystring parameter, but launching the InfoPath based process is simply a reference to the xsn file.
Any best practices for doing this?

+1I've coded so that the XML document template in the XSN file is merged with each row from a SQL query (my driving data). Each XML document is passed into the K2InfoPathSchema field of the K2ROM.Connection Instance.
