I think that the following tooltip is wrong

index.php/fa/28820/0/

Boolean.TRUE is a constant, and even Boolean.TRUE.toString() does not work out.

Wouldn't it be better to have a tooltip saying

The value for annotation attribute Component.property must be a String constant expression?

Thanks a lot

The whole expression is highlighted. If you had just the constant expression Boolean.TRUE, you'd get a different error, i.e., not one about it not being a constant expression but about it being a type mismatch. And an expression such as "tru" + 'e' + 1 is still a constant expression even though the parts aren't all string constants. So really your error is that the overall expression, although of type string, is not a constant, so I don't think adding the type to the error message is helpful because that's not what's wrong.
