I build a very small Dynamic Web Project with Eclipse 3.4 Ganymede
I am using java verison 1.6.0_10, GWT 1.7.0, and SmartGWT 1.3

I have a simple program (see below) that uses a ListGrid and adds it
to
a tab panel.  It compiles and runs under Windows.  It compiles but
does not
run under Redhat Linux.

I get a stack trace that starts at the line where I add the ListGrid
to the TabPanel
and works its way through the GWT library into SmartGWT and fails at
at com.smartgwt.client.widgets.BaseWidget.setProperty(NativeMethod)
at com.smartgwt.client.widgets.BaseWidget.setAttribute(BaseWidget.java:
498)
at com.smartgwt.client.widgets.Canvas.setWidth(Canvas.java.5453)
