ok, here we go: example code that demonstrate the problem (using GWT 2.0 and SmartGWT 2.0) in the development mode. Please, wrap up the code in an EntryPoint class:

Code:

        RestDataSource ds = new RestDataSource();
	String url = "fooUrl";
	ds.setFetchDataURL(url);
        ds.setAddDataURL(url);
        ds.setUpdateDataURL(url);
        ds.setRemoveDataURL(url);      
	    
	OperationBinding fetch = new OperationBinding();
        fetch.setOperationType(DSOperationType.FETCH);
        fetch.setDataProtocol(DSProtocol.GETPARAMS);
        OperationBinding add = new OperationBinding();
        add.setOperationType(DSOperationType.ADD);
        add.setDataProtocol(DSProtocol.POSTXML);
        OperationBinding update = new OperationBinding();
        update.setOperationType(DSOperationType.UPDATE);
        update.setDataProtocol(DSProtocol.POSTXML);
        OperationBinding remove = new OperationBinding();
        remove.setOperationType(DSOperationType.REMOVE);
        remove.setDataProtocol(DSProtocol.GETPARAMS);
        ds.setOperationBindings(fetch, add, update, remove);
        
	 DataSourceTextField textField = new DataSourceTextField("foo");
	 ds.setFields(textField);
	 ds.setDataFormat(DSDataFormat.XML);        
         ds.setShowPrompt(false);
        
	 DynamicForm form = new DynamicForm();
	 form.setDataSource(ds);
	    
	 TextItem textItem = new TextItem();
	 textItem.setName("foo");
	    
	 form.setFields(textItem);
	    
	 RootPanel.get().add(form);
	   
	 textItem.setValue("fooValue");
	    
	 Record record = new Record();
	 record.setAttribute("bar", "barValue");
	    
	 Record record2 = new Record();
         record2.setAttribute("bar2", "barValue2");
        
// comment out the following line for avoiding JavaScripException in GWT dev mode
	 form.setValue("nestedRecord", new Record[] { record, record2} );
	    
	  try {
	        form.saveData(new DSCallback() {
                
                @Override
                public void execute(DSResponse response, Object rawData, DSRequest request) {
                    GWT.log("ok", null);
                    
                }
            });
	        
	    } catch (Exception e) {
	        GWT.log("exception ", e);
	    }

The existence of the server is not important in oder to reproduce the problem.

The exception happens before client manages to send the request to the server.
If the line with form.setValue is commented out, the request is generated and no exception occurs.

The code works under GWT 1.7 and SmartGWT 1.3.

Cheers,

Are you able to reproduce the problem?

Best,

Predrag

Confirmed and fixed - will be in SVN nightlies within a couple of days.

**pedjak** · 30 Dec 2009, 05:31

Thanks a lot!

Not yet fixed

Is that already part of the nightly builds? I have a similar problem with FETCH and therefore tried the provided example against revision.981 from the nightly builds, but the problem is still there with exactly the same result/exception.

I tested the sample against SVN and it works fine.

Thanks for testing.
I'm running Linux, so this might be the problem. I'll get a Windows PC and retry it there to isolate my problem.

**ect** · 1 Mar 2010, 07:31

Fixed

Was not a linux issue, had the same problems with windows.
But the latest svn revision worked, so thanks for patching.
