Hi,
I have a form, where I need to disable some items (the user can't modify
it, but he can see the fields values)
When the user submits the form, before validating it, I set the initial
values for the disabled fields, so this way I can be sure, that
a) The user can't modify any of the disabled fields values
b) The fields get their values (if a field is disabled, then zend_form
won't see its value)
This way everything was fine, until I needed a file upload field. When it
is disabled, I get the following error during form validation:
Fatal error: Uncaught exception 'Zend_File_Transfer_Exception' with
message '"newFile" not found by file transfer adapter' in /jail/web/

I suppose the file upload fields value also doesn't get submitted, but I
don't think setting some value for it before validation will work in this
case.
Do you have any suggestions about dealing with this problem?
Your generic problem is that you can't set the value of a file element.
The value of a file element is the content of the file itself, the user
wants to upload.
So when you want to render the user the filename of a uploaded file you must
use a text element instead of a file element.
You may also want to use the latest release as several issues have already
been fixed since ZF 1.7.
