Runtime type of criteria values in filter editor

[fatzopilot]

I use
JSOHelper.convertToMap((JavaScriptObject) criteriaObject);
to convert criteria entered into the ListGrid filterEditor into java maps.
However, the runtime type of the criteria value always seems to be of type String (except for dates) even when the corresponding field type is set to e.g. Float:

ListGrid.setType(ListGridFieldType.FLOAT);

Shouldn't this generate a criteria value of type Float when mapped to Java?
Setting the editor of the corresponding field to the respective type (e.g. IntegerItem) also does not help.

Another related issue: With a float type editor, i.e.

ListGridField.setFilterEditorType(new FloatItem());

The grid even causes the following error when the column is selected to be show by the user:

When it is show right from the start, this error is raised:

To me it seems there is a layouting problem when a FloatItem is involved...
