ADF Master Table, Inline Detail Table - How to Scroll Range/Disclose Row

Question

JDev 10.1.3.2 ADF/BC
I really need some help here. I've tried as many things as I could think of and I still cannot get this to work.
Scenario: I have query/result page. User clicks a link in the result table to take him to another page. This page has a Master table, Inline detail table component (bound to a tree in the pageDef). Before the page renders, all I want to do is scroll the Master table to the current row (based on the previous query/result via invokeAction in pageDef) and disclose the inline detail. Simple, right? In addition, I'll need to scroll the inline detail to the current row as well.
I would like to do this prior to the components rendering but would be interested in any coding to scroll and disclose.
Thanks in advance,
Tom

I've come up with a solution to my problem. Unfortunately I'm not able to manipulate the table prior to rendering but this solution is probably the closest I'm going to get. Here is my code:
I set up a af:poll component to fire once on my jspx.
    public void poll_PollListener(PollEvent pollEvent) {
        if (this.getFromProcess("unitRowKeyValue") != null) {
            int curIndx = this.getIteratorBinding("UnitsIterator").getRowSetIterator().getCurrentRowIndex();
            this.getUnitTree().setFirst(curIndx);
            if (this.getFromProcess("systemRowKeyValue") != null) {
                this.getUnitTree().setRowIndex(curIndx);
                DisclosureEvent de = new DisclosureEvent(this.getUnitTree(), true);
                this.getUnitTree().queueEvent(de);
            this.storeOnProcess("renderPoll", false);
    }The setFirst method scrolls the table to the index specified. If the user, in my case, has selected a detail item (system), I want to disclose the detail. First I need to setRowIndex to the current index and then I fire a disclose event.
    public void unitTreeDisclosureListener(DisclosureEvent disclosureEvent) {
         if (disclosureEvent.isExpanded()) {
             CoreTable coreTable = (CoreTable)disclosureEvent.getSource();
             RowKeySet rks = new RowKeySet();
             Object test = coreTable.getRowKey();
             rks.getKeySet().add(coreTable.getRowKey());
             coreTable.setDisclosureState(rks);
      }If I don't set the rowKey via the setRowIndex method above, the getRowKey does not return a valid rowKey. In my case, I only want one master row to be disclosed at a time.
This all works great except for a bit of flicker to process the PPR request for the component.
Next step is to see if I can scroll the Inline Detail table to the detail row selected in the Query/Result page.
