Updating cell values in a Row Editable Grid

[sasadorian]

Hello,

My goal is to update a non-editable cell value once a row gets saved.
This is for a Row Editable Grid (http://www.sencha.com/examples/#Exam...oweditablegrid)

This is the code I am trying to get to compile (snippet posted by jtaekema here: http://www.sencha.com/forum/showthread.php?199387-Gxt3-store.getModifiedRecords()-not-actually-returning-modified-records), but having trouble with it:

Replaced X with Staff (which is the type that I am using for my store):

Collection<X> modified = new ArrayList<X>();
for (Store<X>.Record record : store.getModifiedRecords()) {
  X model = record.getModel();
  for (Change<X, ?> change : record.getChanges()) {
     change.modify(model);
  }
  modified.add(model);
}

I have a compilation error for the following line:

for(Store<Staff>.Record record : store.getModifiedRecords()) {

Error states:
Type mismatch: cannot convert from element type Store<Staff>.Record to Store

Any idea why?
If you have another way of getting the changed cell/value so I can apply the changes to a non-editable cell, please let me know.

Thank you.
