-====== Association Editor ====== +====== Selection List ====== 
-This sample demonstrates distinctive feature, dynamically linking objects. + 
 +**Selection List** is a [[SOLoist Sample Applications|SOLoist sample application]] that shows how persistent selections of a subset of objects linked over an association can be implemented by means of another (subsetting) association and the appropriate configuration of the //Element Component//. 
 + 
 +The intention is to enable selection of a subset of //Bank Advisers// that are linked to a particular object of //Person// by checkboxes. 
 + 
 +The particular object of //Person// whose //Bank Advisers// are shown in the list is fetched via a Service Access Point component. It provides the fetched object to its output pin that is wired to the input pin of the list box. 
 + 
 +The list box is configured to render all objects linked to the slot //myBankAdvisers//, but to edit the (subsetting) slot //successfulAdvisers//. 
 + 
 +This way, instead of using Boolean attributes as flags, a subsetting association is used to store the selection. The selection is inherently persistent.
