Hi Christoph,
I have embedded my xhtml code with the form tag, but now I got the
following error
which I always get when I use the form tag:
You should never nest HTML-forms. This leads to unpredictable behaviour in all
major browsers. You can use multiple forms on a page, but they may not be
nested!If you need to disable this check (on your own risk!) set the param
org.apache.myfaces.VALIDATE in your web.xml context parameters to false
I don't understand exactly what nested meens.
Does this meen I mustn't put more than one html tag in a form tag?
Do you think I should change the param. in the web.xml?
Thx Wolfgang
Hi Wolfgang,
make sure that the surrounding h:form has enctype="multipart/form-data".
cheers,
christoph

Hi,
I tried to upload a File but I always got a NullPointerException,
because the uploadFile.getBytes(), uploadFile.getContentType() and
uploadFile.getName()) are null.
I don't understand why?!
Cheers!
