Hi Ernesto,
I have it like as following.
@Override
public void onSubmit(final AjaxRequestTarget target,
Form<?> form)
{
// The veil and the activity indicator are
already on when the code gets
here
String backupFileNameOnServer = null;
try
{
backupFileNameOnServer =
startBackup(parentPage);
}
catch (Exception e)
{
BackupTabPanel.logger.error(e);
parentPage.getSession().error(e.getMessage());
target.add(parentPage.getFeedback());
}
// setup for file download
File sourceFile = new
File(backupFileNameOnServer);
String downloadFileName = "backup_config_" +
getServerName() + "_" +
getTime() + ".tar";
backupFileDownLoadBehaviour.initiate(sourceFile, downloadFileName,
target);
// after this the
AjaxFileDownloadBehaviour#onResponse is called
// then AjaxFileDownloadBehaviour#downloadFile
(overridden in the
local instance) is called
// The veil and the activity indicator are gone
by the time code hits
AjaxFileDownloadBehaviour#onResponse.
}
I did not need to use another thread. Please let me know if you see any
issues with this. Or a better way of doing this.
Much appreciate your help.
Thanks.
