I' ve a more general question: Are there any enhancement concepts for Web Dynpro Java available or at least planned that would give developers the same comfort and possibilities ABAP programmers have?
I mean, will there ever be an Enhancement Framework like in ABAP - modification free enhancements via BADIs or customer exits?
Think of one of SAPs WDJ flagship - the ESS/MSS. If you want to change anything within, you have no other possibility but to modify the sources. Considering this - together with the weak possibilities of backend access via JCo - I give the WDJ not a chance to stand the challenge of WD4A.
