Help with Web Dynpro question

14 Views

I was wondering if someone can help me with the following question in wed dynpro:

1. It is about debugging: Imagine that you have put a break point on a line in your Wed Dynpro program.

The line with a break point calls a method e.g: String name = person.getName();

If you are only interested in know the value returned by the function call, what do you use:

- Step over

- Step into

- Step out

- Step Return

With my experience in other programming languages, i will think that it is Step over. Is that right in SAP?

2. Which one of the following MVC standards are supported by web dynpro?

- Model

- View

- Controller

I was thinking that it is only the "View" since Dynpro is intended to develop User interfaces. But know as well each view or component in Dynpro has a controller (Which could be be the "Controller" part). I am a bit confused by it.

What if the question was asked differently? e.g: what of these MVC standard are contained in a Web dynpro Project?

thanks
