>The only way I see passing the values of from UI to BIZ to DA is by passing them as parameters when instantiating BIZ class and respectively DA class. But the number of this properties/parameters would be too many and kludgy. So I am looking for a better way.

No, there's only one parameter - the object itself.

You'll need something like this (in metacode):

*-- the new object's .init
lparameters toParent
n=amembers(aPr, toParent, "UC")
for i=1 to n
   lcProp=aPr[i]
   do case
      case inlist(lcProp, "name" ... and any other property we want to skip)
*-- do nothing
      case {any other exception}
*-- do nothing
      case pemstatus(this, lcProp, 5)
         this.addproperty(lcprop, getpem(toParent, lcProp))
   endcase
endfor

Not eactly sure of the aPr array, may need to look at what exactly does aMembers do for various parameters - this is just to get you started, but shouldn't need much work.
