Agree. But the TextBox, as far as I saw in the code, turns nulls into empty strings. So it must be the editor framework. Unfortunately this one gets generated, so it is a black box to me right now. Have to dig deeper in the gwt code.
The problem is: it would be easy to workaround the issue, but it would leave me not understanding what is wrong with my code. What did I do to break it? Variable names? Wrong order in initializing something? I don't know. Papick G.

I mean if you assume the object you edit goes (at some time) into the database then I think its desirable to store null (= nothing) into the database instead of "empty data". So I do think its not a bug. Its just how the default TextBox editor implementation (The ValueBoxEditor: http://code.google.com/p/google-web-toolkit/source/browse/trunk/user/src/com/google/gwt/editor/ui/client/adapters/ValueBoxEditor.java) handles empty data. And the difference you see between ValueBoxBase<T> and TextBoxBase is because ValueBoxBase<T> operates on any data type T and if you do not know the type you have to return null in case of an empty String in the wrapped input element. Only subclasses of ValueBoxBase<T> can decide if something like an "empty T" exists and thats why TextBoxBase converts null back to an empty String. An IntegerBox for example cant do that (an empty Integer does not exist) and thus it returns null. -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
