Hi

  1. I have list page created MVVM Design.
  2. On Click of EDIT, i am passing the selected record to the modal window where user will be able to edit.
  3. The modal window has both Save and Exit button.
  4. When i modify the values in the modal window and close the window, i refreshed the list.
  5. But the problem is, when i change some thing and click the exit button, that time also the list is refreshed.

How we can avoid this ?

One thing i can suggest you that rather than using PostGlobalCommand you can use below code..

Binder bind = (Binder) view.getParent().getAttribute("binder");
        if (bind == null)
            return;
        bind.postCommand("doColumnReordering", params);

It will call doColumnReordering method of parentView Model

And i thing rather than passing selected object directly you can pass a new coy of this object because you bind the object and may be you also bind the model object in listbox so if any change will done in object variable it will automatically reflect in Listbox as well so in your childModel window rather than passing elected object directly pass a copy of this object

replace @bind(vm.selectedSchool.code) with @load(vm.selectedSchool.code) @save(vm.selectedSchool.code,before='saveSchool')
