Hi All,
I am new to vaadin. In my current app, i should find whether any of the field (either TextField, or checkbox,Nativeselect) is modified or not in edit page.
if it is edited, I should display message like " Are you sure you want to save changes".
or else save changes directly.
Coming to the question, i tried 2 scnearious
- creating field group
private FieldGroup testFields = new FieldGroup();
String bindUname1=“Uname1”;
String bindUname2=“Uname2”;
final Field txtUname = new TextField(bindUname1);
final Field txtUname1 = new TextField(bindUname2);
testFields .bind(txtUname, bindUname1);
testFields .bind(txtUname2 , bindUname2);
//not working…
if(testFields.isModified()){
}
- directly calling txtUname.isModified()
none of them is working.
Is there any other option to find.
Thanks in Advance
