One of ZK's strengths is rapid prototyping using Zscript classes (which are built using BeanShell). Databind 2 highly relies on Java annotations like @Command/@DependsOn/@NotifyChange, which are not supported by BeanShell. Therefore, one always has to implement real Java classes, methods of Beanshell subclasses cannot have the necessary annotations.

Triggering load/save operations by events directly, like @load(some.bean, after='textbox.onChange'), which would allow developers to work around this, are not supported either. Is this step backwards in terms of flexibility intended, or is the Databind 2 design not matured yet?

Is there any way of defining the annotations in XML files or adding them programmatically?
