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
