Decoder that act as separate functionality

[eclipse-faces-bot]

I suggest to introduce concept of decoders as functionality that works independently from rendering functionality. JSF already has dedicated Renderer class. So it makes sense to do the same thing for decoding functionality. The first benefit from this approach would be possibility to send data from client directly to decoder, skipping on the way to it necessity to use JSF components and JSF life cycle. JSF developers will be able to create more stateless JSF applications and use Javascript libraries in more flexible than now manner.

The first usage of decoder would be the following kind of scenario:

client side: jsf.ajax.post({data:

{'dataHolder.value': value1}

, render: 'input1');

server side: if (isDataRequest(context.getExternalContext().getRequestHeaderMap()))

{ Decoder.handleDataRequest(context); context.responseComplete(); }

... ValueExpression ve = getValueExpression(context, key); ve.setValue(context.getELContext(), o.get(key)); ...

Note: The first argument of the method "post" would be optional and called "url". In case if developer need to customize handling of data from client we will use this argument as way to identify decoder that will handle the data.

Complete signature of the Javascript method could be defined something like this: jsf.ajax.post([url], [data], [handleAs], [render], [onSuccess(data)], onError(data)]);
