[EMF Forms] How to embed a model view inside another model view [message #1239138]

Hi,

I Recently started evaluating EMF Forms framework and at first glance it looks really interesting. When I was playing with it I ran into one problem: how to embed (or rather use) an existing view model inside another one?

For instance, let's assume that we have two classes: (A) and (B). Class (A) has a reference to the (B). I create two view models which show (A) and (B) respectively. Now, I would like to embed the (B)'s view model within the (A)'s view model. As a result, after showing the (A) I should get all details of the (A) and also everything what is declared within the (B)'s view model.

Could you tell me how can I do that?

Hi,

Is the reference between A and B a 1-1 containment? If so, it is
possible to reference attributes of B in the View model of A. However,
in this case, you would need to descriptions of the B view, one
stand-alone, one embedded. If they are exactly the same, this would mean
duplication. We did not have this case before. A potential solution
would be to introduce a new element, which is called "ReferencedView"
which can be contained somewhere in the view model tree. This reference
would need to define the path from the root (A) to B. The renderer would
search for a view model of B and embbed it.

Cheers

Jonas

Hi Jonas,

Thanks for your quick response. Basically, the "ReferencedView" is what I would like to use. Having two view models (and some reference between associated classes) I would like to somehow indicate that "here" EMF Forms should try tor find a matching view model for my referenced object.

index.php/fa/17405/0/

Cheers

Hi,

OK, to make it very clear, you would not use a control in this case, but
another (new) view model element called "ReferencedView", right?
Would you mind to enter a feature request for this?

Regards

Jonas

Hi,

yes, something like that:

I'll enter a new ticket for this.
