Setup Instructions

Suggested change

	receiver.value( null, originalValue.getValue());
	receiver.value( null, originalValue.getExpression());

The value is computed late at rendering time

[loicmathieu]

The implementation is of course naive, I'll handle a better imp later

[loicmathieu]

Please remove it, see the next comment for why

[loicmathieu]

The real implementation of the value extractor would be way more complex.
If it is a templated expression => backoff from validation (return null instead of the template?)
Otherwise, check the target type and convert the expression to the target type.

Then, at some point, we would also need to re-validate a property after rendering it ...

So for you test to work, use an annotation in a String not an int, so the target type is the same.
Then, I'll handle from there I think as I know what to do next ;)
