Re: binding with tranformer question

two classes.
vendorcategories and vendorinfo (with two array
controllers)

vendorinfo has instances of:
vcode, vname, vaddress, vstate, vzip, vcategory (with
setters and getters)

vendorcategories has instances of:
vendorcategoryname, vendorcategorycode (with setters
and getters)

I create an array of vendorinfo from a database query.
so my array is

vendorinfo0
vendorinfo1
vendorinfo2

and I get an array of vendorcategories

vendorcategories0
vendorcategories1
vendorcategories3   etc.


my popup is popuplated from vendorcategories and the
selectedObject is bound to vendorinfo. however
vendorinfo only has the code (I guess I could
de-normalize the database to get the project moving
but I want to figure this out) ... I want to display
the name from the code.

All the binding is done programatically so I thought I
could create a valuetransformer and pass it an array
of vendorcategories so it could transform the display.


1. I can't figure out how to pass this array to the
transformer (and it is conceivable that the  array
could change while the app is running)

2. I don't even know that this is the 'best' solution.
