Dear Group,
I have two "probably simple" questions for using DatePicker in CellTable:
*1. In case, no date had been specified yet, Is it possible to show a empty
Datepicker field?*
I get NPE if date is null, which is probably fine. At this moment, I
populate the date field with current date, which works but is wrong.
I would like to show a message "not specified" and to pop-up a DatePicker
when user clicks on it. ... How do I do this?
*2. I ask user to confirm the new date before it is changed in the DB. How
do I set date shown in the DatePickerCell back to the old one?*
Basically what happens is that the new date shown in the DatePickerCell is
changed to the new date as soon as user chooses a new date from the
DatePicker.
I ask via: Window.confirm() if he is sure to change the date to the new
one, and in case NO, I would like to set the date shown in the CellTable
back to the old one. ... How do I do this?
Thank you in advance for your help:
Nermin B.
Here is my code. The blue marked part is concerned with Question1 and Red
part with Question2.
//=== JobOffeer VALID UNTIL COLUMN
DatePickerCell jobOfferExipreDateCell = new
DatePickerCell(DateTimeFormat.getFormat("dd.MM.yyy hh:mm"));
Column<JobProxy, Date> jobExpireDateColumn = new Column<JobProxy,
Date>(jobOfferExipreDateCell) {
@Override
public Date getValue(JobProxy object) {
if(object.getExpireDate() == null) {
return new Date();
} else {
return object.getExpireDate();
}
}
};
jobExpireDateColumn.setFieldUpdater(new FieldUpdater<JobProxy,
Date>() {
@Override
public void update(int index, JobProxy currentJob, Date
changedExpiredDate) {
if(Window.confirm("Do you want to change expire date to
"+DateTimeFormat.getFormat("dd.MM.yyy").format(changedExpiredDate)+"?")) {
//update job
JobRequest jobRequest =
cp.getRequestFactory().jobRequest();
JobProxy editedJob = jobRequest.edit(currentJob);
//Set New Date
editedJob.setExpireDate(changedExpiredDate);
//(1)Receiver
Receiver<ProcessResponseProxy> receiver = new
Receiver<ProcessResponseProxy>(){
@Override
public void onSuccess(ProcessResponseProxy
response) {
cp.getEventBus().fireEvent(new
LoadDataRequestEvent(LoadDataRequestType.LOGIN_USER));
}
};
//(2) Fire
jobRequest.update().using(editedJob).fire(receiver);
} else {
//ToDo: Reset DatePicker back to
currentJob.getExpireDate();
}
}
});
