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.

    It would be helpful if you could share your code so we can see what you are trying to do. – JimRae May 29 '14 at 19:48
  • what you are describing sounds like standard visual-workflow functionality. When you enter a flow, or pass between one to another, the page refreshes. This makes it challenging if trying to gather information in an apex:form AND from a workflow, but like @JimRae mentioned, without code it is difficult to offer better comments or answers – Tezyn May 29 '14 at 20:07
  • Do you pass the variables as input/output parameters within your flows? And are the variables itself set to input AND output? – westerforce Apr 20 '15 at 6:52

If the issue is related to the page render, I would suggest you add a rerender tag on your interview lines and just update the panel you have the flows running in.

Thanks for sharing your code. I'm trying to run it to compose a solution for you. The component code is missing the /apex:component closing tag, so I don't know how much was cut off the end, but it won't save in its current state. There is no code provided for the Visualforce page, and the Class needs some custom objects, e.g. asset_in_meal__c, before it will save. Then, the flows are missing, as well...

Consider reducing your sample to the minimum required to illustrate the problem, and provide the complete package. Short of that, we can only speculate vs. provide a working solution.

  • The calling VisualForce page only calls this component, headers and sidebar. The full code is quite large and does incorporate both custom and standard objects. The issue I'm having is flows within flows are not passing data via variables. I'm not sure how to post what the flows are. – MarcoC Jun 1 '14 at 10:43
