Running queries in af:query panel dirties current transaction?

Question

Hi,
I've met the following issue (JDev 11g, build 5188): I'm using a custom action handler for the Back button in my pages that checks whether there are uncommitted changes before navigating back to the previous page. If the transaction is dirty, the user is sent a confirmation dialog that asks whether to commit or rollback changes before leaving the edit form.
To identify a dirty transaction, it uses the following code snippet as suggested by Steve Muench:
BindingContext bc = BindingContext.getCurrent();
boolean txnDirty = bc.findDataControlFrame(bc.getCurrentDataControlFrame()).isTransactionDirty();Now this normally works fine, until I added an af:query panel to the page itself, with ResultComponentId set to my edit form. Now, the search runs fine too, however when performing a search and then leaving the page, the transaction is dirty and I get the confirmation dialog even if no data were modified at all.
That is, I just open the page, run a search and leave the page, no edits whatsoever. This makes txnDirty=true for some reason. Why is running a search through af:query marking my data as modified? Can I disable this behaviour?
I tried with a custom query listener which does suspendTransaction() for the current datacontrol frame, runs the query invoking "#{bindings.MyViewCriteriaQuery.processQuery}", then resumeTransaction(), but nothing changes.
Suggestions, anyone?
thanks,
RickyS

Hi am using the following code (javascript) -- Jdev(11.1.1.3)
function preventUserInput(evt){   
var eventSource = evt.getSource();
var popup1 = eventSource.findComponent("showGlassPanePopup");
if (popup1 != null){
AdfPage.PAGE.addBusyStateListener(popup1,handleBusyState);
evt.preventUserInput();
//JavaScript call back handler
function handleBusyState(evt){ 
var popup = AdfPage.PAGE.findComponentByAbsoluteId('r3:0:r1:0:showGlassPanePopup');
if(popup!=null){
if (evt.isBusy()){
popup.show();
} else if (popup.isPopupVisible()) {
popup.hide();
AdfPage.PAGE.removeBusyStateListener(popup, handleBusyState);
... End of Code..
This line .. (popup.isPopupVisible()) removes the Popup , if popup is visible...
