    Error when I try to load a DS with records that have a java object in Attribute

    When I try to insert a record with an attribute of type "JavaObject" in DataSource, I have an exception that I describe below (not very informative):

    Code:
    YourClientOnlyDataSource.getInstance().addData(selectedRecord,new DSCallback() {
	public void execute(DSResponse response,
		Object rawData, DSRequest request) {
		system.out.println("Not up here!")
}
});
    However, it works when I add the record to the RPC DataSource with the following statement:
    Code:
    List<ListGridRecord> records = new ArrayList<ListGridRecord>();
for (YourDataObject data : result) {
	ListGridRecord newRec = new ListGridRecord();
	copyValues(data, newRec);
	newRec.setAttribute("Object", data);
	records.add(newRec);
}
response.setData(records.toArray(new Record[records.size()]));
processResponse(requestId, response);
    You should note that this object then I want it back:
    Code:
    YourDataObject myObject = (YourDataObject) selectedRecord.getAttributeAsObject("Object");
    I wonder if you can help me. Thanks!

    For a JavaScript error, capture the Developer Console contents *in compiled mode* on specific browsers to get a stack trace. See the FAQ for details.

    It looks like you've posted a bunch of code involving GWT-RPC. If you think this is a bug that doesn't involve GWT-RPC, please post a minimal test case.

      I'm sorry for not providing all the information needed. Only in debug mode fails!

      It has nothing to do with GWT-RPC. Only I indicated to illustrate a case where it works properly (in compiled and debug mode)
      Code:
      //com.smartgwt.client.data.DataSource
List<R> records = new ArrayList<R>();
YourDataObject yourData = new YourDataObject();
ListGridRecord myRecord = new ListGridRecord();
myRecord.setAttribute("name", yourData.getName());
myRecord.setAttribute("location", yourData.getLocation());
myRecord.setAttribute("Object", yourData);

records.add(myRecord);
response.setData(records.toArray(new Record[records.size()]));
processResponse(requestId, response);
      I simplify everything in one file to reproduce the problem. I try to capture with smart console but I can not capture anything (not in debug mode or compiled mode).

      All code (much shorter) involved in the problem, is attached. For me, it fails in debug mode is a big problem

      Thanks!
