How to make changes to standard UWL WebDynpros?

Hi,

We are faced with the problem to make changes to the standard UWL Person Search Dialog. But couldn't find any documentation, blog or anything else how to achieve this. We strongly believe, that we have to create a new track in nwdi, import uwl development components, make changes to them, transport and so on.

So, how can we make changes to standard uwl WebDynpro components?

Thanx,

Gerald
