Composition of exterior wall

I just started a small remodeling project, converting the Sun Room into a Dining Room. Anyway after removing one wall that attaches directly to the house I noticed that there is not any plywood under the foam board. Is this normal? Shouldn’t there be some sort of plywood sheeting then a vapor barrier then the foam board then the exterior siding? Did I make any sense?

As strange as it seems, many houses are built that way, and it meets code. Some areas only require solid sheathing on the corners of the building. If it's a "sunroom" that wasn't originally meant to be living space, even that may not apply- it's hard to say.
