I have a workflow that queries table and when there is available data it calls another workflow and retrieves the relevant data and then pushes it to a web service. This is supposed run every 2 minutes.
Previously I had some test data in my variable bar, but I have long since removed it. Yet that data is getting pushed to the webservice constantly.
Why is the workflow still using the old test data?
Flowgear caches sub-workflows on first encounter when they execute from a parent workflow. If you've modified a sub-workflow and re-saved it, that change won't take effect in the calling workflow until you restart it.
