Hi, i have a listbox one column have a decimalbox, when i need to save data i loop the list and i set a custom constraint on each decimalbox, then i loop the listbox again to fire the constraints (set focus, get value). But sometimes the message constraint dissapear, simply doesn't show it, and the red rectangle no show either; i don't know the possible reason. Has anyone had a similar problem?
i'm using MVVM
If you call getValue() inside, that will throw WrongValueException and break the loop. So you will just trigger one error message in the end.
Hence, it's better to validate it and call decimalbox.setErrorMessage() to show errors for all decimalboxes.
If this is not your case, please show the code about how you trigger constraint errors.
@hawk thanks for your answer here the code:
for (Listitem fila:listbox.getItems()) {
if (fila.getChildren().get(3).getChildren().get(0) instanceof Decimalbox) {
Decimalbox dbox = (Decimalbox)fila.getChildren().get(3).getChildren().get(0);
dbox.setFocus(true);
}
}
button.setFocus(true);
for (Listitem fila:listbox.getItems()) {
Component comp = fila.getChildren().get(3).getChildren().get(0);
if (comp instanceof Decimalbox) {
Decimalbox dbox = (Decimalbox)comp;
try {
dbox.getValue();
} catch (WrongValueException e) {
LOGGER.error(e.getMessage());
throw e;
}
}
}
button.setFocus(true);
i don't why sometimes work, sometimes don't
