How to define selectedRowKeys for a table?

Question

Hi,
I have a table defined in jsff page and it is not defined using searchResultsIterator. Instead it is defined using CollectionModel.
How can I define the selectedRowKeys attribute for this table?
Table code:
<af:table value="#{pageFlowScope.PipeProvidesListBean.pipeProvidesCollectionModel}"
var="row" emptyText="#{inventoryUIBundle.TABLE_EMPTY_TEXT_NO_ROWS_YET}"
selectionListener="#{pageFlowScope.PipeProvidesListBean.providesPipeSelectionListener}"
rowBandingInterval="0" id="t1"
rowSelection="#{pageFlowScope.PipeProvidesListBean.rowSelection}"
binding="#{pageFlowScope.PipeProvidesListBean.resultsTable}">
<af:column sortProperty="id" sortable="false" headerText="#{inventoryUIBundle.ID}" id="c5">
<af:commandLink action="summary" id="cl1" actionListener="#{bindings.openSubTaskForSummary.execute}">
<af:setActionListener from="#{row.oid}" to="#{objectId}"/>
<af:outputText value="#{row.id}" id="ot1"/>
</af:commandLink>
</af:column>
<af:column headerText="#{inventoryUIBundle.NAME}" id="c1">
<af:outputText value="#{row.name}" id="ot5"/>
</af:column>
</af:table>
Thanks

You can limit the number of rows using a trigger. Below is quick and dirty example that has not been fully tested.
test@ORCL> create table rowlimit (col1 number);
Table created.
Elapsed: 00:00:00.34
test@ORCL> create or replace trigger limit_rows
  2  before insert
  3  on rowlimit
  4  declare
  5    v_count number;
  6  begin
  7     select count(*)
  8     into v_count
  9     from rowlimit;
10
11     if v_count >= 4 then
12       raise_application_error(-20000, 'Table can have no more then 4 rows');
13     end if;
14  end;
15  /
Trigger created.
Elapsed: 00:00:00.09
test@ORCL> insert into rowlimit values(1);
1 row created.
Elapsed: 00:00:00.03
test@ORCL> insert into rowlimit values(2);
1 row created.
Elapsed: 00:00:00.00
test@ORCL> insert into rowlimit values(3);
1 row created.
Elapsed: 00:00:00.00
test@ORCL> insert into rowlimit values(4);
1 row created.
Elapsed: 00:00:00.00
test@ORCL> insert into rowlimit values(5);
insert into rowlimit values(5)
