Hi,
Suppose there is some problem or exception in the file download. Let's say
in the following method:
protected IResourceStream getResourceStream() {
return new AbstractResourceStreamWriter() {
public void write(Response output) {
WebResponse response = (WebResponse)output;
byte[] buffer = new byte[256];
try {
int read;
while((read = is.read(buffer)) != -1) {
response.write(buffer, 0, read);
response.flush();
}
response.close();
} catch (Exception e) {
response.write(e.toString().getBytes());
response.close();
}
}
};
}
And I want to show the error in the feedback panel for the page. How can I
do that? The AjaxRequestTarget is not available here. I tried to do
something like the following but it did not work:
parentPage.getSession().error(error);
WebApplication app = (WebApplication)getComponent().getApplication();
AjaxRequestTarget target = app.newAjaxRequestTarget(parentPage);
target.add(parentPage.getFeedback());
I also tried saving the AjaxRequestTarget passed in the initiate method as a
member variable of the class and use it later for posting the error. Well,
for one it did not work. For second, I got the non serializable error for
the target in the log.
Thanks
