XWT + TableViewer + Handler + open vs load Behaviour [message #502601]

I have a handler containing a method
protected void rowSelected(Object sender, Event event) {
System.out.println("Row Selected Event !")
}

When using a stand alone program to invoke XWT.open, "rowSelected" is called. XWT open was used here
XWT.open(url, getSG());

However, when I use the same XWT and run it as eclipse product, I get the following execption
org.eclipse.e4.xwt.XWTException: Event handler "rowSelected" is not found.
Only differnece is XWT.load is called
XWT.load(parent, url, getSG ( ) );

Did I miss anything ?

Thanks
- Walter.

It is a problem of class loader. You need to add the folowing code before calling XWT.load() or XWT.open()
XWT.setLoadingContext(new DefaultLoadingContext(this.getClass()
.getClassLoader()));
