Ok. So now I can add and edit without error or duplicates. Solution
was...
If it breaks something else i'll post it but so far this worked for
me. Please not that I am saving the product with transfer and the call
the function below, passing through the saved transfer object as
object and form has a hidden field in it which contains the id of the
productcategory, or shelf as i call it.
<cffunction name="setRelationships" access="public"
returntype="Struct">
<cfargument name="object" type="Struct" required="true">
<cfargument name="form" type="Struct" required="true">
<cfset shelf =
transfer.get("basic.Shelf",ARGUMENTS.form.shelfidfk)>
<cfif NOT shelf.containsProduct(ARGUMENTS.object)>
<cfset shelf.addProduct(ARGUMENTS.object)>
<cfset transfer.save(shelf)>
</cfif>
<cfreturn ARGUMENTS.object>
</cffunction>
