Mapping one node to many nodes

Oct 02, 2005 at 10:51 AM | 5 Views

How do you map one node in a controller context to many other nodes in another controller context?

Here's the situation I'd be using this.

I have an Adaptive RFC model from which I created a Custom Controller. I then used the wizard to map to the model.

The model corresponds to RFC functions and many of those functions accept the same parameters, LanID for instance. I simply want to have one "LanID" node in a controller that I would set. The change would then propagate to the other LanID context nodes in the Custom Controller mapped to the model.

What's the best way to handle this?

    Hi Bernard,

    I'm not sure exactly what you are attempting, but when you have mapped nodes (or attributes), there is only ONE version of the data, which all the nodes use. So if you change attribute data in ANY context, all the nodes/attributes which are mapped to this, immediately see the new data. It doesn't matter if you "set" the data of the original attribute, or any of the mapped attribtutes. The end result is the same.

    Regards,

    Walter

      Found it. The Relate Context Attribute wizard is what I was looking for. The dialog allows the mapping between one node from one controller to many in another controller. It even generates the binding code. This wizard if found in the Data Modeler, right clicking on a controller and selecting "Apply Template".
