inputFileUpload issue when file does not exists
I am using the inputFileUpload Tomahawk component to upload files.
Everything works great except when the user types the file path and file
name directly into the input field. If the file path is wrong or the file
does not exists, there is no error messages displayed. I would like to
display a message to the user that the file does not exists. Is there a way
to validate if the file exists?
<h:form id="form1" enctype="multipart/form-data">
<h:panelGrid columns="2" columnClasses="label,value" styleClass="form">
<h:outputLabel value="* File:" for="fileupload"
styleClass="formLabel"></h:outputLabel>
<h:panelGroup>
<t:inputFileUpload id="fileupload"
accept="image/*"
value="#{fileBean.uploadedFile}"
storage="file"
styleClass="fileUploadInput"
required="true"
maxlength="180"></t:inputFileUpload>
<h:message id="msgFile" for="fileupload" showDetail="true"
errorClass="errorMessage" infoClass="infoMessage" fatalClass="fatalMessage"
warnClass="warnMessage"/>

Maybe it is a "feature" of IE, haha. Thanks a lot Martin, I will definitely

Re: inputFileUpload issue when file does not exists

Hi jorge,
the HTML file-upload behaviour in IE is severely flawed. What you
could do is what Gmail is doing: just not display the file-entry-field
at all, display a link which allows the user to choose the file,
internally connect the link with the hidden file-input field via
JavaScript, then the interaction becomes a lot better...
regards,
Martin

Re: inputFileUpload issue when file does not exists

Actually, the behavior is different when I use FireFox. Silly me, I’ve only
been using IE to trace this issue. When I use FireFox and have an invalid
path or file name, the inputFileUpload field is bank out then I get “This
field is required” error since I require that field. Which is a much better
behavior that what I get using IE.
I did install the Live HTTP headers module in FireFox and I can see that the
filename field is indeed clear out before it is sent to the server. Is there
anything I can do for the IE users about this issue?
thanks,
Jorge

are you sure you don't any message in that case? do
you have a <h:messages /> in your page?
try to set showDetail="true" and showSummary="true"
for the h:messages and see if you get anything.

Does the browser actually send anything back to the server in that case?
If not, then there is nothing that can be done about that on the server
end...
For firefox, you can check this by installing the excellent
"live-headers" addon, and seeing what data (if any) the browser sends to
the server. Tracking that info down for other browser types is a little
more difficult..

Yes, but the problem is that my uploadAction method in my backing bean does
NOT get executed when the file name is invalid or the file does not exist.
Nothing happens when I click on the command button.

Re: inputFileUpload issue when file does not exists
Posted by Nitin Deshmukh <de...@yahoo.com>.
why don't you check if the file is null in the action
method of the Bean. and if it is null or its size is
zero, then add a Faces message for this component.
e.g.
in your jsp
<t:inputFileUpload id="fileupload" accept="image/*"
value="#{fileBean.uploadedFile}" storage="file"
styleClass="fileUploadInput" required="true"
maxlength="180"></t:inputFileUpload>
<h:message for="fileupload" />
<h:commandButton action="#{fileBean.uploadAction}" />
Now in your fileBean, add the action method
public String uploadAction() {
if (uploadedFile == null || uploadedFile.getSize()
== 0) {
FacesContext.getCurrentInstance().addMessage(="fileupload",
new FacesMessage(FacesMessage.SEVERITY_ERROR, "File
null", "Please specify a not null file."));
return null;
}
}
I hope it helps.

Matthias,
Thanks for your reply. The problem is that my validator is not being
executed. By the way I am running myfaces 1.1.5. Has anyone run into this
issue?

Re: inputFileUpload issue when file does not exists
Posted by Matthias Wessendorf <ma...@apache.org>.
Hi,
I only know that Trinidad creates a 0 byte file, when there is an
"invalid" file,
so a validator would work in Trinidad that way.

Re: inputFileUpload issue when file does not exists
Posted by jorge08 <jo...@gmail.com>.
I've added a validator attribute to the inputFileUpload component, but it is
not fired unless I have a valid file specified. Here is what I have:
<t:inputFileUpload id="fileupload"
accept="image/*"
value="#{fileBean.uploadedFile}"
storage="file"
styleClass="fileUploadInput"
required="true"
validator="#{fileBean.validateFileExistance}"
maxlength="180"></t:inputFileUpload>
And in my backing bean I have:
public void validateFileExistance(FacesContext context, UIComponent
toValidate,Object rcvRecord)throws Exception{
FacesMessage message = new FacesMessage("Inside validateFileExistance");
FacesContext facesContext = FacesContext.getCurrentInstance();
facesContext.addMessage(toValidate.getClientId(context),message);
...
}
Any ideas?

that can solve the issue, but only when you are not interested in
empty file (such as "flag files").

You could add a custom validator that check the length of the uploaded file?
