Hi Christoph,
I tried to get the upload running since 2hours...
Now I used this example:
http://www.irian.at/myfaces/fileupload.jsf
I copied it one by one, but I had to remove some stuff, because I got
some errors.
But the stuff I removed was just outputtext...
I got the same nullpointer exception as ever :(
But I think it can't be too hard to set up just a "simple" upload field.
Given that I can't find any other good examples via google, I want to ask
if you know a good website which shows step by step the creation of such
a upload field?
Thanks Wolfgang
Hi Wolfgang,
this means that you already have a h:form-tag in your page,
surrounding the one with id "upload".
You can either remove this form and switch the enctype on the outer one.
Or if the form is included in a template, and you don't want to have
the enctype "multipart/form-data" for all your views you can set the
enctype dynamically via a binding.
public HtmlForm getForm(){
HtmlForm form = (HtmlForm)
getApplication().createComponent("javax.faces.HtmlForm");
String currentViewId =
FacesContext.getCurrentInstance().getViewRoot().getViewId();
if(currentViewId.equals("/some_upload_form.xhtml")) {
form.setEnctype("multipart/form-data");
}
return form;
}
cheers,
Christoph

Hi sorry forgot to put the new html code inside.
Here it is:
<h:form id="upload" enctype="multipart/form-data">
<t:inputFileUpload
id="myUploadedFile"
storage="file"
accept="image/*"
styleClass="myStyle"
value="#{ home.uploadFile}"/>
<h:commandButton
actionListener="#{home.upload}"/>
</h:form>
