Hi Nagma,

What does this line of your code signify? String propList = attr.getValue(PropertyConstants.PROP_LIST).toString(); What is the attr object? From where are you retrieving it?

If am not wrong, you want to get all lists and their values which are used in any P3 attribute of all available subclasses in your system, right?

Based on my understanding of your requirement, here is a small code snippet which you may like to leverage to build up your program:

IAdmin admin = session.getAdminInstance();
IAgileList list;
for(IAgileClass ac : admin.getAgileClasses(IAdmin.CONCRETE)){
      System.out.println(ac.getName());
      for(IAttribute at : ac.getAttributes()){
           if(at.getFullName().startsWith(“Page Three”)){
                 list = at.getAvailableValues();
                 if(list!=null && list.getAdminList() != null){
                     System.out.println(at.getFullName()+” –> “);
                     if(list.getAdminList().getValues().getChildNodes() !=null){
                         for(Object tn : list.getAdminList().getValues().getChildNodes()){
                              System.out.println(((IAgileList)tn).getValue());
                         }
                     }
                 }
            }
      }
}
session.close();
Runtime.getRuntime().exit(0);

You asked a simple question that requires a fairly complex answer, because one must account for static and dynamic lists, as well as flat and cascading lists. 
The code below is a functioning groovy example of collecting list values for a given subclass and cell.
It works. i’m sure it can be improved, (i’m interested in any improvements to it).  it runs on Agile 9.3.6

// given:
// sdk – the agile session
// subclassName – the agile subclass name
// apiName – a given cell apiname
// return:
// the list of values, if any.

subclass = sdk.getAgileClass(subclassName)
attribute = subclass.getAttribute(apiName)
listName = attribute?.getProperty(‘List’)?.getValue()
list = sdk.getAdmin().getListLibrary().getAdminList(listName as String)

println “subclass|$subclass|attribute|$attribute|list|$list”

items = []

// STATIC LISTS
if( list.isEnumeratable() ) {

        // STATIC NON-CASCADED LISTS
        if( !list.isCascaded()) {
                items = list.getAdminList()?.getItems().findAll{it.isObsolete() == false} as String[]
        }
        // STATIC CASCADED LISTS
        else {
                items = []
                adminList = list.getAdminList()
                adminList.getItems().findAll{ it.isObsolete() == false}.each {
                        if (it.parentItemID == 0) {
                                it.children.each { items.add( “${it.name}|$it” )}
                        }
                }
        }

} else { // DYNAMIC LISTS — Use the list’s query to get its items.

        adminList = list.getAdminList()
        criteria = sdk.getAdmin().getNode( adminList.getCriteria().getProperties()[‘ID’] )
        QCLASS = (criteria) ? criteria.getCriteriaClass() : list.getListAgileClass()
        QQUERY = (criteria) ? criteria.getCriteria() : “”

        items = sdk.query( QCLASS, QQUERY ).collect { row ->

                value = row.getCells()[0]
                // you could handle special cases here, for example: 
                if( QCLASS.toString() == ‘Users’) {
                        fname = row.getValue(‘firstName’)
                        lname = row.getValue(‘lastName’)
                        uid = row.getValue(‘userID’)
                        value = “$fname $lname ($uid)”
                }
                return value
        }
// done.
}
println “items:(if any)”
items.each {println it}
