Problem with DataSourceEnumField and Chrome dev mode

[phuqit]

Latest nightly, gwt 2.1.1, chrome 8.0.552.237.

I use this code to populate the datasource enum field:

        DataSourceField type = new DataSourceEnumField("type", "Type");
        Map<String, String> typeEnumValues = new LinkedHashMap<String, String>();
        typeEnumValues.put("CONTAINER", "Container");
        typeEnumValues.put("TEXT", "Text");
        typeEnumValues.put("INTEGER", "Integer");
        typeEnumValues.put("FLOAT", "Float");
        typeEnumValues.put("BOOLEAN", "Boolean");
        typeEnumValues.put("DATE", "Date");
        typeEnumValues.put("DATE_TIME", "Date/time");
        typeEnumValues.put("LINK", "Link");
        typeEnumValues.put("ENUM", "Enumeration");
        typeEnumValues.put("IMAGE", "Image");
        typeEnumValues.put("FILE", "File");
        type.setValueMap(typeEnumValues);

and calling

type.getValueMap();

returns this

{DATE_TIME=Date/time, INTEGER=Integer, BOOLEAN=Boolean, FLOAT=Float, ENUM=Enumeration, LINK=Link, CONTAINER=Container, TEXT=Text, __gwt_ObjectId=252, DATE=Date, FILE=File, IMAGE=Image}

Where the ... is this "__gwt_ObjectId=252" coming from?! Works fine on firefox.
