I'm trying to bind a workflow input to a Date so that the Date picker can be used when the UI runs. As part of the workflow I need to update the date so I try to bind the input parameter to an existing Date instance. I've noticed that binding does not seem to work for Date. This is vRO 7.6. I also tried binding to an action that returns a Date object after converting a string to a Date. That also does not seem to work.
On a related note, I've noticed that the object returned by the date picker has the toISOString() method but the object returned by Date() does not support it. Are there two Date types in vRO?
