Cause of this error -You are trying to pass a primitive object into a generic type declaration whereas generic types always expect a Wrapper Class object. So please use ‘Boolean’ instead of ‘boolean’ in your code i.e. ‘B’ in caps.
I don’t know that there is an option to create a watch expression directly from Xcode 4’s code window. If there’s something in the code window you’ll want to add an expression watch for, I think you’ll have to copy that code to the clipboard. Then while debugging, make sure the debug area is being … Read more

You can pass it to a BeanShell bsh.Interpreter, something like this: Interpreter interpreter = new Interpreter(); interpreter.eval(“result = 5+4*(7-15)”); System.out.println(interpreter.get(“result”)); You’ll want to ensure the string you evaluate is from a trusted source and the usual precautions but otherwise it’ll work straight off.

To summarize the various levels at which the codec can be applied: Set Config.groovy’s grails.views.default.codec=”html” to get HTML escaping by default on all ${expressions} in the application. Then when you want to default a whole page back to none, use the directive: <%@page defaultCodec=”none” %> or <%@ defaultCodec=”none” %> To disable HTML encoding for one … Read more
The reason this happens is that Age is a value type. In order to coerce an expression returning a value type into Func<Person,object> the compiler needs to insert a Convert(expr, typeof(object)), a UnaryExpression. For strings and other reference types, however, there is no need to box, so a “straight” member expression is returned. If you … Read more
This problem occurs because you are trying to mock Select method, which is an extension method, not an instance method of IEnumerable<T>. Basically, there is no way to mock an extension method. Have a look at this question for some ideas that you may find useful. UPD (12/11/2014): To gain more understanding on mocking extension … Read more

It lacks an initializer. The second paragraph doesn’t apply … Read more
