In our project we need to set default values in dependent fields for different view models.

With ZK7 we implemented a mechanism described here:


With the new ZK 8 form approach that does not work, is there any way to do with ZK8?

Thank you all :)

I updated two classes TestObserver and TestObservableForm from the zkfiddle example

Here is what I did for ZK 8 with them:

  1. Change the implementation from the interface of FormImpl to Form and FormProxyObject, and then in your example, it requires a Map-like implementation used in the Zul file (like fx.value and fx.date), so I implement TestObservableForm to extend from MapProxy, which was created since ZK 8.0.0 release.
  2. Override the method of put() to intercept the value of the field when it has changed to trigger its notifyChanges() method (the same as setField() for ZK 7)
  3. Replace the usage of TestObserver with the put() method of Map instead.
