Hi all,
I need some help on using tapestry's form component on GAE.
I am uploading a file & a beaneditor with a tapestry form component.
The problem is that when the file gets uploaded to GAE, I get an exception.
This exception occurs because, tapestry wants to create the file for me.
Is there a way of avoiding this automatic creation of file after uploading
the form?
GAE does not allow to create files!
And I must use the tapestry component form :)
Thanks,
Fernando
