While migrating to RAP 2.1-RC3 I want to add some pieces of behaviour to the client-component of a DateTime widget. Instead of writing a custom widget I would like to use ClientScripting (as recommended). Unfortunately there are only a few methods on client side to read the actual (server-)state of a widget. Text widgets are the only widgets which are currently supported by get-methods. Are there any plans to fully supoprt the DateTime widget in the coming releases (RAP 2.1, 2.2, 2.x, 3.x)?
Thx for any support / hints in advance

Hi Thorsten,
this is an interesting idea. Please open an enhancement request and we
will discuss the possibilities there.
Thanks,
Ivan

As long as I can't use ClientScripting for modfying my DateTime widget I started a migration towards RAP 2.1 recently.
I am using rap-internal qooxdoo classes. After replacing all qt.* objects within my widget by rwt.* objects I finally created the TypeHandler. My java and javascript compile successfully but the widget isn't displayed. I suppose there is a link missing which inserts my widget into the actual dom tree of the browser.
I looked at the CKEditor example and noticed a remarkable difference. In constructor of CKEditor a parent is set:
this.remoteObject.set("parent", WidgetUtil.getId(this));
On client side (javascript) the created widget is added to the dom tree:
this.parent = rap.getObject( properties.parent );
this.element = document.createElement( "div" );
this.parent.append( this.element );
I adopted this pattern to my widget. But my app crashes while accessing 'properties.parent' in javascript with the following error: "entry is undefined".
I debugged a little bit and ended up in this method of rap-client.js:
getObject : function( id ) {
var entry = rwt.remote.ObjectRegistry.getEntry( id );
var result;
if( entry && entry.handler.isPublic ) {
result = entry.object;
} else {
result = this._.getWrapperFor( entry.object );
}
return result;
}
'entry' is null here (while debugging CKEditor I got a value). Why is my parent object of my DateTime widget null while there is a value in CKEditor? I don't see the difference.
Any ideas what's going wrong?

Can you sysout/console.log what the value of "WidgetUtil.getId( this )"
on the Server and "properties.parent" on the client is? Also, is the
widget you attach to a Composite?
Greetings,
Tim
Hi Tim,
in the meantime I changed my strategy for migrating the DateTime widget. I just migrated the UI and made the necessary modifications on the LCAs... and it's fully functional now. Next step might be switching the protocol from LCAs to the new JSON based one...
Up to now it feels a lot better and easier to write custom widgets using the new protocol instead of those LCAs... I think this is a solid foundation starting with RAP 2.0.
Regards
Thorsten
