s:fileupload validation

[sbozdag]

Hi,

I am trying to make sure that user specified a file to upload. @NotNull did not worked. I have then read something on SeamProblemsFAQ (http://wiki.jboss.org/wiki/Wiki.jsp?page=SeamProblemsFAQ) about a @NotNull issue.

I am now using required attribute for s:fileupload . But it did not worked for me..

 <h:form id="fileUploader" enctype="multipart/form-data">
 <h:panelGrid columns="2">
 <h:outputLabel for="file">File:</h:outputLabel>
 <s:fileUpload id="file" data="#{fileUploader.resultsFile}"
 contentType="#{fileUploader.contentType}"
 required="true"
 requiredMessage="You must specify a file"/>
 </h:panelGrid>

 <!-- Buttons and other stuff -->
 ...
 </h:form>

Thank you

Don't push the data directly into an entity, use an action component instead - probably the one you already have for the submit action. Then validate it in the submit action method manually.

Thanks for replying. Yes, I am using an action component already. Annotations are really easy to use and maintain. That was the reason I would like to put them in.

Anyway, I will make validation manually for data.
