I've created a visualforce page that has a "popup" (aka outputpanel that is rendered when the flow is called). This works fine for Flows that don't reference another flow.
I've created a flow that has another flow embedded in it, but it will not show the second flow on my visualforce page. What appears to be happening is when the second flow is called the visualforce page is being called again, thus running the constructor in the custom controller. By default the popup is set to rendered=false, so the second flow never runs.
As part of debugging I've set the popup to always render. I can see the data pass bewteen the inital flow and the one being called. The first three flows work just fine.
All I can think of is to set a flag in an object to indicate that the flow is still active, so when the inital flow calls others the outputpanel continues to render.
