I'm having a problem getting the file object when I use FormPanel, FileUploadField, and Spring. Here is what I have: I added the CommonsMultipartResolver bean to my Spring Context file: <pre><code><bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="maxUploadSize" value="100000"/> </bean> </code></pre> I have a model class with the regular getters and setters: <pre><code>pulic class UploadItem{ private String filename; private CommonsMultipartFile fileData; .... getters/setters .... } </code></pre> My controller class: <pre><code>@Controller @RequestMapping("/Foo") public class ThingController extends BaseController implements ServlerContextAware{ .... @RequestMapping(value = "/bar", method = RequestMethod.POST) public @ResponseBody String createFile(UploadItem item, BindingResults results){ String orgFile = item.getFileData().getOriginalFilename(); return orgFile; } </code></pre> I'm using UiBinding to create the form fields, but I'm calling the fileupload field and formpanel to add the other methods in code. I have a submit button that calls: <pre><code> form.submit(); </code></pre> And my constructor I take care of the other form requirements: <pre><code> form.setMethod(Method.POST); form.setEncoding(Encoding.MULTIPART); form.setAction("http://url.com/foo/bar"); form.addSubmitCompleteHandler(new SubmitCompleteHandler(){ @Override public void onSubmitComplete(SubmitCompleteEvent event){ String results = event.getResults(); Info.display("Upload Response", results); } }); </code></pre> When I run the code I get a nullpointerexecption on item.getFileData().getOriginalFilename(); I don't know what the problem is.

Guidance

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.
