I was going through the VSphere5 documentation there it's mentioned that "OGNL expressions in workflow presentations is not supported in releases of Orchestrator later than 4.1."
Is there is any alternative to OGNL expression to support dynamic input parameters during workflow?
vCO 5.5.x Release Notes say otherwise - "The use of OGNL expressions in workflow presentations is supported." So I guess the message is a little bit confusing for the customers.
At the moment, there is no alternative to OGNL. Perhaps in some future version...
