Hi,
I have converted a rcp application from eclipse 3.4 to eclipse 3.5.
In my application I bind some text widget to model object. My model's
object aren't of type String.
When the class ValueBinding set the converted value to text widget, I have
an Exception.
The reason is class WidgetStringValueProperty, method:
protected void doSetValue(Object source, Object value) {
doSetStringValue(source, (String) value);
}
It's possibile to change to
protected void doSetValue(Object source, Object value) {
doSetStringValue(source, value == null ? "": value.toString());
}
Or exists another solution?

This being the case, your converter should be returning a String instead
of some other Object.
