I'm updating a double value in a datagrid to using a custom parser on an
EditTextCell. If the parser throws an error, then I'm trying to put the
original value back by redrawing the row. But, the erroneous value stays
in place. Stepping through the code, I do see it going through
HasDataPresenter's setRowData method, and even see the original value in
the row object. But, that value doesn't get drawn.
If I now click on the cell again, then click away without editing, then the
original value does get written into the cell. That led me to try a
deferred command, which didn't work, hence code below with a ridiculous
delay before redrawing (which, needless to say, also doesn't work).
If it makes any difference, I'm using a SingleSelectionModel.
Am I doing something wrong here? Or is there a better way to check the
values as they're being entered?
@Override
public void update(final int index, R item, String value)
{
double doubleValue = 0.0;
boolean needsRedraw = false;
try
{
if (value != null && !value.isEmpty())
{
doubleValue = MyFormat.PARSER.parse(value);
needsRedraw = true; // added
}
item.setAmt(doubleValue);
thisCell.clearViewData(item);
}
catch(Exception e)
{
needsRedraw = true;
}
if (needsRedraw)
{
//grid.redrawRow(index);
Scheduler.get().scheduleFixedDelay(new
Scheduler.RepeatingCommand() {
public boolean execute() {
grid.redrawRow(index);
return false;
}
}, 1000);
}
}
});
