Possible bug in smartgwt ListGrid

[jlpuffe]

I am using smartgwt 3.1p-2012-12-06 and gwt 2.4.

I am using Firefox 3.6.

I get the error' Unable to get a pointer to this item's focus element' when I select the mini date range icon. If I use the earlier smartgwt 3.0 it does not give me this error.

Here is the code:

public class MyClass implements EntryPoint {

public void onModuleLoad() {
VLayout layout = new VLayout();
ListGrid miniGrid = new ListGrid();
ListGridField entryDate = new ListGridField("entry_date", "Date");
miniGrid.setFields(entryDate);
entryDate.setFilterEditorType(new MiniDateRangeItem());
miniGrid.setHeight(595);
miniGrid.setWidth(200);
miniGrid.setAutoFetchData(false);
miniGrid.setShowFilterEditor(true);
layout.addMember(miniGrid);
layout.draw();

}
}

Apparently this error only shows up when I try to run this project from my IDE tool (Eclipse). If I war up the project and deploy it to jboss I don't see the error.
