I have a similar problem with popoups and loosing the connection to the selection. I am wondering if you can shed some light on the problem...

basically, I have two popups (Category and SubCategory). If the user changes the Category, the action method then goes off to the backend to get the list for the subcategory.

this is a copy of what I sent to the email@hidden mail list.:

any chance this looks similar....?

++++++++

I am still having a bear of a time with some popups. I have objects ContactCategory and SubCategory

one ContactCategory many SubCategory(s)

My ContactCategory.java has setters and getters for an array of subcategories

public NSArray<SubCategory> theSubCategories() {
   return _theSubCategories;
}

public void setTheSubCategory(NSArray<SubCategory> theSubCatArray) {
   this._theSubCategories = (NSMutableArray<SubCategory>) theSubCatArray;
}

I read the Categories with:

contactCategoryList = ContactCategory.fetchAllContactCategories(contactEC);

then:

for (int i=0; i<contactCategoryList.count(); i++) {

  EOQualifier qual = SubCategory.CONTACT_CATEGORY.eq(contactCategoryList.objectAtIndex(i));
  NSArray<SubCategory> subCatArray = (NSArray<SubCategory>)SubCategory.fetchSubCategories(contactEC, qual, null);

  contactCategoryList.objectAtIndex(i).setTheSubCategory(subCatArray);
}

My popup buttons are bound like this:

CategoryPopUpEE : WOPopUpButton {
list = contactCategoryList;
id = "categoryEEPopUpID";
displayString = categoryObjectForPopUp.categoryTitle;
item = categoryObjectForPopUp;
selection = current.contactCategory;
}

CategoryPopUpEEObserveField : AjaxObserveField {
   updateContainerID = "SubCatEEDiv";
   observeFieldID = "categoryEEPopUpID";
   fullSubmit = false;

}

SubCategoryEEUpdateContainer : AjaxUpdateContainer {
   id = "SubCatEEDiv";
}

SubCategoryPopUpEEField : WOPopUpButton {
list = current.contactCategory.theSubCategories;
id = "subCatEEID";
displayString = subCatObject.subCatTitle;
item = subCatObject;
selection = current.subCategory;
}

My problem:
When I view a record, I can change the CategoryPopUpEE and saveChanges or I can view a record and change the SubCat however, if I change the CategoryPopUpEE and the subCategoryPopUp list changes I can select a new subCat but the selection is not updating the selection binding.

I even tried to add an observeField that was watching the SubCategoryPopUpEEField with an action. If I view a record, then change the subCategory I get joy. However if I change the Category the observed action method does not fire when I change the SubCategoryPopUpEEField.

Help please.

What else can I send to help me through this dilemma?
