Hi,
Probably I'm doing something wrong, but I declare a binding as follow:
IObservableValue emfObs = EMFEditObservables.observeValue(editingDomain,
getModelObject(),
MyEMFPackage.Literals.MYOBJ__MYEATT);
myTextRidget.bindToModel(emfObs);
myTextRidget.updateFromModel();
but this does not work, The #updateFromModel is executed and the value
is rendered in the text-field, but a UI-to-Model Update does not work.
EMF has a separate DataBindingContext with different
UpdateValueStrategies. Is it possible to use a EMFDataBindingContext (I
want the use the capabilities EMF.Edit provides)? -
I didn't see any possibility to override or extend to provide my own
databinding-context.
Thx for your help
Tom

Hi Tom,
- using your own DataBindingContext is not supported. Please file an
enhancement request so we can keep track of this.
http://www.eclipse.org/riena/bugs.php
- feel free to attach a standalone example (or projects) to that bug, so
we can experiment with your issue without spending lot of time with EMF.
- I know that other people on the newsgroup use EMF and Riena. Has this
been a problem, or how did you work around this?
Kind regards,
Elias.

Hi,
If you rely on the default converters you need to use an
EMFDatabindingContext because EMFObservables report the structural
feature as the value-type.
If Riena doesn't allows you to set it you can work around by explicitly
setting an converter but that's far from ideal :-)

that's exactly the problem. It seems to me I can not set this context.

This is one of the rare cases the DB creators failed a bit because the
Databinding-Context is not the appropriate location for this. It would
be better if I one could plug-in his/her own converters.
Something like:
------------8<------------
DatabindingContext dbc = ... ;
dbc.setConverterStrategy(....);
dbc.setValidatorStrategy(....);
------------8<------------
There's a bug with a discussion about this problem and possible solution
but this won't get fixed in time of 3.5.

Maybe. But I'm wondering if this "failure" can't be workarounded by
Riena itself with providing some API for using my own DatabindingContext.
Any thoughts?
