Hello,

is there a way to reuse a view model? I created a "base" view model and want to add this in other viewmodels.

Regards,
Dennis

If the domain model elements inherit from each other, you can use View
proxies for this...

If i click View Proxy in the IDE-Tooling , it will create a new VerticalLayout which contains some controls. But how can I select another view?

Hi,

what do you mean exactly by "It will create a new VerticalLayout"?
During runtime? Do you reference another view by its ID?

Best regards

Hi,

could it be, that this occurs only, if the preview is open? If so, this
seems to be a bug. View proxies are replaced during runtim and the
preview might do that. It should therefore work on a copy. Could you
retest this and report a BR?

Thanks!

Yes first it's a view proxy model. If i press the refresh button it will replaced by the vertical layout.

What is the view proxy id? A Resource URI? The path to the other view model?

That is the id which is used to register the view model (in the
extension point).
