I have a schema of an Object, let's call it cus:object. User can create an Object instance or modify existing one selected in folder using the Form cus:object.
There is also another schema - cus:provider - where the data of Providers (external systems) are stored.
Object and Provider has no logical links - they are not using each other in real world.
So cus:object and cus:provider don't have a link (<element type="link"... />) to each other also.
Provider is a piece of information obtained from a CSV file importing to AC on a daily basis - so if it was existing yesterday it might be deleted today and vice versa.
What I need right now is a button on the Object's form which will call the SOAP method and pass an array of Providers that user have selected. There is no need to store the combination of "Object-Provider" after.
I'm wondering if I can define something like a temporary schema inside cus:object form just to use linkList input, or, what might be better, - if I could create something like a subform using cus:provider as a schema and returning the selection to parent form as a /temp/selection xpath?
