Still not sure I completely understand. I think you mean that you want two
columns in your table, and that each row could be either a B or a C. Is that
correct? If so, that would certainly work, but the property names of each bean
would have to be the same, so that they match the column names. For example,
let's say the column names are "foo" and "bar". Then your B and C beans can
define properties like this:
B : MyBean {
foo: A
bar: A
}
C : MyBean {
foo: A
bar: A
}
Does that help?
