I have found the reason for this....

In older version, the setter of the backing bean (for the UploadedFile field) was not \
called if the value is null. So the value in the backing bean which was stored when \
previewed was not overwritten.

In new version the setter is being called even if the value (the file path and name) \
in the inputfile control is null, and hence the value(the contents of UploadedFile) \
in the backing bean are being overwritten when called the setter with null.

I don't which behavior is correct. I guess the bug is in the older version, because \
for all other controls the setters were called even if the values are null.

Thanks
Srikanth

Subject: Issue with file upload after upgrading from 1.0.6 to latest
(6/21 build)


I am finding some issues with the new version... fixing one by one.... Then next one \
is...

I have a file upload component to upload a picture. The user picks a picture from the \
file dialog and  hits open. Now the user has two choices..

  1) Submit the form, in this case it works as desired (the selected picture is shown \
to the user).  2) The user can preview before submitting the form by clicking a \
preview button. When user clicks it, he/she will see the selected picture on the form \
and then submits. It was working fine in the old version, but with the new version, \
the preview works fine but after submitting the form the user is not seeing the new \
picture he/she selected. After user previews the selected picture the file path and \
name is gone from the text box of upload control (same in the old version). If I put \
the file path and name back into the text box before submitting  the form it works \
fine. So it seems that the control is looking for value in the text box in the new \
version.

What is the difference between old and new versions, is this a bug or do I need to do \
something different in new version ?

TIA
Srikanth

If you use the x:message/x:messages tags, you get meaningful names as
a present along the way ;)
