Answer 1

This is exactly what I'm looking for...I just can't make it work. I have 2 tables (database and schema). They are related via a database_id column. My code is below if you are willing to help.
HTML Header
<script>
function get_select_list_xml1(pThis,pSelect){
var l_Return = null;
var l_Select = html_GetElement(pSelect);
var get = new htmldb_Get(null,html_GetElement('pFlowId').value,
'APPLICATION_PROCESS=CASCADING_SCHEMA',0);
get.add('P7_DATABASE',pThis.value);
gReturn = get.get('XML');
if(gReturn && l_Select){
var l_Count = gReturn.getElementsByTagName("option").length;
l_Select.length = 0;
for(var i=0;i<l_Count;i++){
var l_Opt_Xml = gReturn.getElementsByTagName("option");
appendToSelect(l_Select, l_Opt_Xml.getAttribute('value'),
l_Opt_Xml.firstChild.nodeValue)
get = null;
function appendToSelect(pSelect, pValue, pContent) {
var l_Opt = document.createElement("option");
l_Opt.value = pValue;
if(document.all){
pSelect.options.add(l_Opt);
l_Opt.innerText = pContent;
}else{
l_Opt.appendChild(document.createTextNode(pContent));
pSelect.appendChild(l_Opt);
</script>
Application Process
BEGIN
OWA_UTIL.mime_header ('text/xml', FALSE);
HTP.p ('Cache-Control: no-cache');
HTP.p ('Pragma: no-cache');
OWA_UTIL.http_header_close;
HTP.prn ('<select>');
HTP.prn ('<option value="' || 0 || '">' || '- All Schemas -'
|| '</option>'
FOR c IN (SELECT schema, schema_id
FROM (SELECT schema, schema_id, database_id
FROM schema_lookup
WHERE database_id = :cascading_selectlist_item_1)
LOOP
HTP.prn ('<option value="' || c.schema_id || '">' || c.schema || '</option>');
END LOOP;
HTP.prn ('</select>');
END;
P7_DATABASE_ID Form Element Attribute
onchange="get_select_list_xml1(this,'P7_SCHEMA_ID');
P7_SCHEMA_ID LOV
select SCHEMA d, SCHEMA_ID v from SCHEMA_LOOKUP
where DATABASE_ID = :P7_DATABASE_ID
order by 1
