    <p>I'm having a problem uploading a file using spring webflow 1.0 and struts 1.3.</p> <p>The jsp is something like this:</p> <pre><code>&lt;html:form action="/flowAction" method="post" enctype="multipart/form-data"&gt; &lt;!-- snip --&gt; &lt;html:file property="file" name="attachDocumentsForm" size="50"/&gt; &lt;!-- snip --&gt; &lt;/html:form&gt; </code></pre> <p>The Form is something like this:</p> <pre><code>public class AttachDocumentsForm extends SpringBindingActionForm { // note, SpringBindingActionForm extends struts' ActionForm private FormFile file; //snip } </code></pre> <p>Now, my problem is that when I submit the form, the <code>file</code> field is always <code>null</code>. The other fields on the form are filled out properly, and if I dig through the <code>RequestContext</code>, I can find the file is buried deep some of the data structures there. </p> <p>Here is the <strong>horribly</strong> ugly way that I can get at the attachment:</p> <pre><code>// 'context' is the RequestContext ServletExternalContext servletExternalContext = (ServletExternalContext) context.getExternalContext(); ActionForm form = (ActionForm) servletExternalContext.getRequest().getAttribute("actionForm"); FormFile file = (FormFile) form.getMultipartRequestHandler().getFileElements().get("file"); </code></pre> <p>I've noticed that the <code>MultipartRequestHandler</code> on my form is <code>null</code>, and I suspect that this might be part of the problem, but I've tried populating it with an instance of <code>CommonsMultipartRequestHandler</code> to no avail.</p> <p>What do I need to do to let the <code>file</code> field be populated correctly?</p>

    1. COShouldn't you be able to get the file from the ActionForm accessor, using (FormFile) form.getFile()?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
