How to verify transaction state under a tab in Dynamic Tabs UI Shell?

Question

Hi,
I'm using Dynamic Tabs UI Shell to load taskflows under dynamic tabs. If a particular taskflow under a tab becomes dirty, upon close I should warn the user. What is the best way I could check if this particular taskflow has become dirty?
Thanks,
Pramod Gujjeti

Hi Pino,
Thanks for the reply.
The given URL only handles scenarios assuming a region from a flow has no flow embedded within it. And it seems to be not a generic approach to handle dynamic tab close.
I'd worked on a similar but more generic approach which could of use to this thread watchers, hence posting the code:
In the method that is invoked on tab close:
boolean isTransDirty = false; // holds the transaction state of the dynamic tab content for which close event is fired
try{
DCBindingContainer dcBindingContainer = (DCBindingContainer) AdfUtils.resolveExpression("#{bindings}");
dcBindingContainer = (DCBindingContainer)dcBindingContainer.getExecutableBindings().get(this.getSelectedTabIndex());
if(dcBindingContainer != null){
for( Object exeBinding : dcBindingContainer.getExecutableBindings() ) {
isTransDirty = isTransDirty(exeBinding);
if(isTransDirty){
break;
System.out.println(" is Trans Dirty : " + isTransDirty);
}catch(Exception e){
e.printStackTrace();
// method isTransDirty(Object ..)
private boolean isTransDirty(Object exeBinding){
boolean isDirty = false;
try{
if(exeBinding instanceof JUIteratorBinding ){
JUIteratorBinding juIteratorBinding = (JUIteratorBinding) exeBinding;
System.out.println(" Iterator : " juIteratorBinding.getName() "\t" + "D.C : " + juIteratorBinding.getDataControl().getName());
isDirty = juIteratorBinding.getDataControl().isTransactionDirty();
if(isDirty){
System.out.println(" Dirty because of " + juIteratorBinding.getName());
return isDirty;
}else if(exeBinding instanceof DCTaskFlowBinding){
DCTaskFlowBinding dcTaskFlowBinding = (DCTaskFlowBinding) exeBinding;
for( Object taskflowExeBinding : dcTaskFlowBinding.getExecutableBindings() ) {
isDirty = isTransDirty(taskflowExeBinding);
if(isDirty){
return isDirty;
}else if(exeBinding instanceof JUFormBinding){
JUFormBinding jUFormBinding = (JUFormBinding) exeBinding;
for( Object juFormIterBind : jUFormBinding.getIterBindingList() ) {
isDirty = isTransDirty(juFormIterBind);
if(isDirty){
return isDirty;
for( Object juFormExeBinding : jUFormBinding.getExecutableBindings() ) {
isDirty = isTransDirty(juFormExeBinding);
if(isDirty){
return isDirty;
}catch(Exception e){
e.printStackTrace();
return false;
}
