Hi Jianwu, I just checked, and indeed it is possible to open a model, run it, and while it is running, open and run other models.
I verified this by opening and running the PN Nondeterministic Merge demo and then opening other demos, including the SDF Sound Spectrum demo. Every thing worked, which is what I hoped for, but had not checked recently. If Josep Maria can open a second workflow inside an already existing Kepler process, than that would help avoid the hsqldb issue. _Christopher Jianwu Wang wrote: > Hi Christopher, > > Thanks for your explanation.
