ADF 11.1.2 rollback again

I have an editable list with a child editable list and wanted all my list to retain there position on rollback so I wrote some code.

Had to be slightly tweaked from what I user to have.
The first method saves all current iterator binding positions to a IteratorPosition class (just a pojo with range start etc getters and setters - nothing fancy)
The second method restores those positions to the iterator bindings and all is now working as I want.

Also remember this button is a toolbarbutton with the following: partialSubmit="false" immediate="true"
and a resetactionlistener - without these things it may not work correctly.


public static Map saveBindings() {   Map returnValues = new HashMap();   ArrayList list = ADFUtils.getDCBindingContainer().getAllIterBindingList();   for(Object listItem : list) {     if(listItem instanceof JUIteratorBinding &&
      !"listIter".equalsIgnoreCase(((JUIteratorBinding) listItem).getName())) {       JUIteratorBinding bondage = (JUIteratorBinding) listItem;       Row row = bondage.getCurrentRow();       int rangeSize = bondage.getRangeSize();       int rangeStart = bondage.getRangeStart();       int currentRowIndexInRange = bondage.getCurrentRowIndexInRange();       if(row != null && rangeSize > 0) {         IteratorPosition pos =
          new IteratorPosition(rangeSize, rangeStart, 
            currentRowIndexInRange, bondage.getCurrentRowKeyString(), row);         returnValues.put(bondage.getName(), pos);       }     }   }   return returnValues; } public static void restoreBindings(Map bindings, boolean isDelete) {   if(bindings != null) {     ArrayList list = ADFUtils.getDCBindingContainer().getAllIterBindingList();     for(Object listItem : list) {       if(listItem instanceof JUIteratorBinding) {         JUIteratorBinding bondage = (JUIteratorBinding) listItem;         IteratorPosition pos = bindings.get(bondage.getName());         if(pos != null) {           if(isDelete) {             ViewObject vo = bondage.getViewObject();             bondage.setCurrentRowIndexInRange(pos.getCurrentRowIndexInRange());             vo.setRangeStart(pos.getRangeStart());             if(!pos.getCurrentRow().isDead()) {               Row[] rows = vo.findByKey(pos.getCurrentRow().getKey(), 1);               if(rows != null && rows.length == 1) {                 int ridx = vo.getRangeIndexOf(rows[0]);                 if(ridx != -1) {                   vo.scrollRangeTo(rows[0], ridx);                   vo.setCurrentRowAtRangeIndex(ridx);                 }               }             }           } else {               bondage.setRangeSize(pos.getRangeSize());               bondage.setRangeStart(pos.getRangeStart());               bondage.setCurrentRowIndexInRange(
                pos.getCurrentRowIndexInRange());           }         }       }     }   } }
