/**
 * FormItem that creates an HTML &lt;input type="file"&gt; control, with an interface that allows a user to pick a file
 * from his machine to upload to the server. <P> <b>NOTE:</b> use {@link com.smartgwt.client.widgets.form.fields.FileItem},
 * <b>not</b> UploadItem, if you are using the Smart GWT Server framework.  FileItem is much easier to use and addresses
 * all the limitations of UploadItem discussed below.  See the {@link com.smartgwt.client.docs.Upload Uploading Files}
 * overview for details. <P> If a form containing an UploadItem is {@link com.smartgwt.client.widgets.Canvas#redraw
 * redrawn} (which may happen if other form items are shown or hidden, the form is {@link
 * com.smartgwt.client.widgets.Canvas#getRedrawOnResize resized}, or this or other items show validation errors) then  the
 * value in the upload item is lost (because an HTML upload field may not be created with a value).  For this reason, if
 * you are building a form that combines an UploadItem with other FormItems that could trigger redraw()s, recommended
 * practice is to place each UploadItem in a distinct DynamicForm instance and create the visual appearance of a single
 * logical form  via combining the DynamicForms in a {@link com.smartgwt.client.widgets.layout.Layout}.  For the same
 * reason, do not apply  {@link com.smartgwt.client.widgets.form.validator.Validator validators} to UploadItems: if such a
 * validator fails, it will  cause the form to be redrawn and the UploadItem's value to be lost. <P> <B>NOTE:
 * Browser-specific behaviors:</B>  <ul> <li> while getDisplayValue() can be used to retrieve the filesystem path of the
 * uploaded file on some browsers, different browsers will return either just the file name without path or the full path. 
 * It is plausible that some browsers may switch behavior in the future to not supply this value at all.  Do not rely on
 * this value. <li> the appearance of the UploadItem is not consistent across browsers and we do not recommend trying to
 * make it consistent or trying to apply styling to the upload control at all.  It is a potential security problem if an
 * end user is unable to reliably recognize the upload control, hence, all browsers limit what styling can be applied. 
 * Various hacks exists to get further control of styling, but it is likely these hacks will be broken by browser upgrades
 * in the future. </ul>
