GXT DualListField throws Exception

[mikeb]

GWTDesigner throws an exception anytime I try to use a GXT DualListField

Scenario:
1) create a new blank GXT Window or GXT LayoutContainer
2) drag/drop a new DualListField onto the emptry Windor or LayoutContainer
3) watch GWTDesigner churn for 2 seconds and then navigate to an exception/support window

See attached exception info.

Give this a try using the latest GWT Designer build...
