Handler activation [message #925202]

Hi,

In e3 we have the concept of activeWhen and enabledWhen for handlers. How does this translate to e4?

In e4 we have the "visible when" attribute in the application model. Does that translate to the old activeWhen expression?

Then there is the @CanExecute annotation for handlers. I guess this translates to enabledWhen?

This then also means that handlers must be instantiated to find out if they can be enabled, right? There is no lazy enabledWhen any more like we use to have with core expressions?

Thanks for clarifying,

Best regards,

Wim Jongman
