How to make the application temporarily stop (pause)

Question

Hi,
I'm using Jdev 11.1.2.3.0
My use case is:
+ I have index.jsf: load list of regions (List<TaskFlowBindingAttributes>)
+ in an action of one region (For ex: A-flow.xml), i will add another region to the list of regions
addDynamicRegion("B-flow);  
+ My requirement is: all codes after <<addDynamicRegion("B-flow); >> will be wait util the app finish adding B-flow.xml and get out of B-flow
+  this action is the same with : Call_Form Built-in of Oracle Forms
P/s: my addDynamicRegion is just simple :
public void addDynamicRegion(String flowId) {
RunForm runForm = (RunForm)JSFUtils.getManagedBeanValue("runForm");
TaskFlowBindingAttributes taskAtt = new TaskFlowBindingAttributes();
String flowName = flowId.replace("-", "_");
taskAtt.setId(flowName);
taskAtt.setTaskFlowId(new TaskFlowId("/WEB-INF/" + flowId + ".xml", flowId));
runForm.getTfBindingAtts().add(taskAtt);
UIComponent form = getFormComponent(FacesContext.getCurrentInstance().getViewRoot());
AdfFacesContext.getCurrentInstance().addPartialTarget(form);
Thank you very much

Hi,
  this action is the same with : Call_Form Built-in of Oracle Forms
no, its not because a call form navigates to the called form module, which is comparable to a task flow call activity and not a region.
http://imdjkoch.wordpress.com/2010/07/23/open_form-vs-call_form-vs-new_form/
"Runs an indicated form while keeping the parent form active. Oracle Forms runs the called form with the same Runform preferences as the parent form. When the called form is exited Oracle Forms processing resumes in the calling form at the point from which you initiated the call to CALL_FORM."
(Note: I appreciate any ADF vs. Forms comparison if technically its done correctly)
The regions in a view load according their af:region tags and as such you wont be able to pause loading unless you use the activate condition to point to a managed bean property that returns false so that the region is not initialized.
This is from the JavaDocs of the Class TaskFlowBindingAttributes.
"Set of attributes that define a TaskFlowBinding object. The taskFlowList attribute of the multiTaskFlow element of the page definition uses a list of object of this type to describe each taskflowBinding that the multiTaskflow binding contains. The order of this list defines the order of the region objects in the multiTaskflow binding. "
So adding a region does not give you a chance to stop further loading and you will have to work with not activating not yet loaded regions, which then you need to load manually.
