Hello.
I'm working in a GWT application, using your SmartGWT product (release 2.2).
I have written a little test case to show what I'm trying to do, to get some feedback about what could be wrong. Basically, I have a ListGrid with a partial view of a DataSource (only some fields), when one of the list cells is clicked, a form is loaded with the selected Record, allowing to edit its values. To avoid server requests, form rememberValues is called on edition, and before saveData, valuesHaveChanged is called to avoid communication is nothing changed.
Every time, DynamicForm.valuesHaveChanged is called, I get this exception, in development mode (on a Firefox 3.6.3 client):
In the original code, I was working with ValuesManager to control a set of DynamicForm instances, with the same results.
Is there anything wrong in the usage I'm making of DynamicForm.valuesHaveChanged? Any idea to avoid this failure?
I'm attaching a testcase, to illustrate the effect.
Best regards.
