Trouble Refreshing Child VO

Question

I am using Jdevelper 11.1.1.6.
In my use case I have a screen that lists a databound table of rows (parent row of a parent/child relationship). Each parent row can have 1 to many children. The table has 4 columns, the first 3 columns come from the Parent table. The 4th column is a count of how many rows are associated to it in the child table. The user can select a row and click the edit button. The edit popup form is displayed. It displays the 1st 3 columns as read only text fields. A 4th object is in the form. This object is a listbox listing the assigned children. I have some instances where the listbox doesn’t always display all of the assigned children because the children are updated via external Stored Procedures while I am in the application. Here is the backing bean code that I have implemented. I need to find a way to get a fresh copy of the Child Iterator before doing “lParentRow.getChildren()”. Do you have guidance on how I might be able to do this.
public void onEditPopupFetchAction(PopupFetchEvent pPopupFetchEvent) {
try {
DCIteratorBinding lDciter =
(DCIteratorBinding)getBindings().get("Parent1Iterator");
ViewObject lParentVO = lDciter.getViewObject();
ParentVORowImpl lParentRow = (ParentVORowImpl)lParentVO.getCurrentRow();
RowIterator lAssignedChildren =
lParentRow.getChildren();
String lAssignedChildren = "";
while (lAssignedChildren.hasNext()) {
ChildVORowImpl lChildRow =
(ChildVORowImpl)lAssignedChildren.next();
lAssignedChildren +=

Hi,
the method only shows the part that accesses the children. It does not show anything beyond (e.g. how the value is returned). I don't recommend accessing the View Object from the client and instead expose the method as a client interface on the View Object to be accessed from a method binding in ADF. This is if you want to follow ADF best practices.
To solve your problem try
lParentRow.refresh(Row.REFRESH_CONTAINEES);

Ps.: Please consider moving the code to the ViewObjectImpl for best practices
