Hi,
in my RCP I use EMF databinding. In this case an SWT Text should be bind to an field that is a double. Therefore I use:
IObservableValue observeTextObserveWidget = WidgetProperties.text(SWT.FocusOut).observe(text);
IObservableValue currentSelectionObserveValue = EMFEditObservables.observeValue(editingDomain, currentSelection, Literals.USER__VALUE);
bindingContext.bindValue(observeTextObserveWidget, currentSelectionObserveValue, null, null);
But this text field doesn't show anything. And if I type in a value, it isn't set in the model.
Do I miss something in the usage of EMF databinding with double values?
The databinding of this double works within a TableViewer and also works with this text field, when I use Bean Databinding.
Best regards
Bastian

you don't show use the DatabindingContext you create but my guess is
that it is *NOT* an EMFDatabindingContext which is *has to be* to make
conversions work!
