I have the following CellTable
When the user clicks the Pay Min. CheckBox, it should copy the value from the Due Now column over to the Pay Today text field AND recalculate the total for the Pay Today column.
Here is the code for the CheckboxCell (Pay Min.) and the TextInputCell (Pay Today) columns:
private Column<AccountInvoice, Boolean> buildPayMin() {
columnPayMin = new Column<AccountInvoice, Boolean>(new CheckboxCell(true, false)) {
@Override
public Boolean getValue(AccountInvoice object) {
return object.isPayMinimum();
}
@Override
public void onBrowserEvent(Context context, Element elem, AccountInvoice object, NativeEvent event){
// Get event type
int eventType = Event.as(event).getTypeInt();
// See if this is a 'change' event
if (eventType == Event.ONCHANGE) {
String value = columnMinDue.getValue(object);
// Get the cell to copy the value from
TextInputCell cell = (TextInputCell) columnPayToday.getCell();
// Re-create the view data for the cell
TextInputCell.ViewData viewData = new TextInputCell.ViewData(value);
cell.setViewData(object, viewData);
// Refresh
cellTable.redraw();
event.preventDefault();
event.stopPropagation();
}
}
};
columnPayMin.setDataStoreName(columnPayMinHeader);
columnPayMin.setHorizontalAlignment(HasHorizontalAlignment.ALIGN_CENTER);
columnPayMin.setVerticalAlignment(HasVerticalAlignment.ALIGN_MIDDLE);
return columnPayMin;
}
// -----------------------------------------------------------
private Column<AccountInvoice, String> buildPayToday() {
columnPayToday = new Column<AccountInvoice, String>(new TextInputCell()) {
@Override
public String getValue(AccountInvoice object) {
return object.getPaymentAmount();
}
};
columnPayToday.setDataStoreName(columnPayTodayHeader);
columnPayToday.setFieldUpdater(new FieldUpdater<AccountInvoice, String>() {
@Override
public void update(int index, AccountInvoice object, String value) {
object.setPaymentAmount(value);
cellTable.redraw();
}
});
return columnPayToday;
}
I can get the value to copy over, but the total for the Pay Today column doesn't refresh. It seems to refresh only when a value is manually entered into the Pay Today text field. I even tried doing:
columnPayToday.getFieldUpdater().update(context.getIndex(), object, value);
which didn't help either.
Thanks for any help you might provide.
ViewData
represents a temporary value in your TextInputCell. When you call cellTable.redraw()
, the TextInputCell reverts to the original value (the one from getValue()
method for that column).
Do not redraw the table if you want to modify only the "view" state of TextInputCell, or call accountInvoice.setPayToday#
(or whatever method is there) to update the object and then call refresh() on your ListDataProvider (which is a more efficient way to update a table compared to redraw).
