[Trinidad] How to show a FacesMessage inside a custom UploadFileProcessor?
Hi all,
We are trying to implement a custom UploadFileProcessor to be able to show a
message to the user when the file he wants to upload is too large to be
handled by Trinidad.
By now, Trinidad throws an EOFException, but it can not be handled in
anyway, isn't it? How could we show a FacesMessage to the user telling what
the problem is without propagating the exception?
Thanks in advance,
- - Rafa

Hi Matthias,
I have been trying to override the validate method for a custom component,
but I have been facing problems of configuration and trinidad is still using
the CoreInputFile. Because of deadlines of the project I am working in, I
can not spend more time in this solution. I hope in the future I will have
time enough to solve it this way.
Anyway, we have a custom phase listener and have created a custom
UploadedFileProcessor to catch the EOFException. In the afterPhase() of the
phase listener, we look for a key in the requestMap that is set in the
processFile() if this exception occurs. Less elegant, I know, but at least
it was easy to make it work :)
Thank you for your tips!!

I am traveling to the rest of the week;
But, I can try to do a "prototype" in Trinidad next week.
Like provide a *modified* input-file comp.
I haven't really spent time on it, but there is this bug:
http://issues.apache.org/jira/browse/TRINIDAD-607
and we are aware of the related issues;

Thanks for your help Matthias. I will try to override the validate() for the
component on Monday

or better, override the validate()
of the component, to check for a key.
b/c not really a conversion error, more
validation

I haven't looked into this particular thing, but we already have a bug
for it in our jira.
Perhaps it is worth to check this:
the size-check is done in UploadedFileImpl.load()
catch that exception and return null from processFile().
when there is an exception store a "flag" in the requestMap.
currently the SimpleInputFileRenderer.getSubmittedValue()
reads the UploadedFiles map, and does this:
get(clientId) (to get the file)
you could provide your own renderer for that,
and in check for the error
@Override
public Object getConvertedValue(
FacesContext context,
UIComponent component,
Object submittedValue)
{
//check for the error
}
let me try this on our side as well.
