I have to use the DYNAMIC-PROPERTY function in OpenEdge to get data out of a class.

So far this works just fine, but now I would like to know the data type of the values that was retrieved. This is required because the values are formatted based on the data type.

So for example:

CLASS Customer:
DEF PUBLIC PROPERTY Name AS CHAR NO-UNDO
GET.
SET.

DEF PUBLIC PROPERTY Email AS CHAR NO-UNDO
GET.
SET.

CLASS Invoice:
DEF PUBLIC PROPERTY Amount AS DECIMAL NO-UNDO
GET.
SET.

DEF PUBLIC PROPERTY Customer AS Customer NO-UNDO
SET.
GET.


In another procedure I would like to do something like this:

DEF INPUT PARAM oInvoice AS Invoice NO-UNDO.

DEF VAR theValue AS Progress.Lang.Object NO-UNDO.

theValue = DYNAMIC-PROPERTY(oInvoice, "Amount").

IF theValue:WHATS-THE-TYPE = "decimal" THEN
RETURN STRING(theValue, ">>>>>9.99").
ELSE
RETURN TRIM(theValue). // It is a character field


Since I don't know the type at runtime, I can't format the value.

In a later stage I would even want to get the property values of the customer.

IF theValue:WHATS-THE-TYPE = "Customer" THEN
RETURN DYNAMIC-PROPERTY(theValue, "Name").
