Webdynpro debugging and performance

[Former Member]

Hi all,

1) Other than Break - points , are there any techniques for debugging the Webdynpro applications ?

2) How to calculate the performance of the Webdynpro applications & how to increase the performance of the webdynpro applications ?

3) How to pass parameter in webdynpro application URL?

4) In context of webdynpro what is Stateful applications & stateless applications?

5) How to Refresh Node in Webdynpro ABAP?

Thanks

Hi,

Below is a link from SAP portal that talks about web dynpro debugging.

Hope this comes to your help regarding the first point.

I thought it was a case of 'deja lu'.

The certification test must be looming - time to hit the study books!

You already posted this before (http://scn.sap.com/thread/3305659). You shouldn't post the same question multiple times.

Hi,

This sounds like a study list! Shouldn't you be hitting the books, rather than posting on SCN?

cheers

Hi,

     1.     If you are using EHP 5 or higher yes there are differnt ways to debug WDA especially designed for WDA.

     2. For performance...its just the conventional way, however there is some better tools recommended/developed by SAP AG.

     3.     Passing parameters : mentioned above

     4.     Stateful/Stateless : - WDA is stateful as there is nothing being done at client end. intitally there were possibilities to use javascripting and all in WDA. However due to security constraint, SAO do not recomend using such things. So what it does is almost every calculation in backend, Hence its stateful. You can browse though for more details

     5.     The only way is I know is mentioned above. Do some RnD its possible that you may find all new fancy details

Hi,

Apart from normal break points, i dont think there is any other way to debug.

performance of WD applications can be increased using assistance class. Method calls of assistance class are faster. Try to reduce the heirarchy of UI elements in layout. Dont use deep layouting.

What parameters you want to pass into URL? You can refer this : http://help.sap.com/erp2005_ehp_04/helpdata/en/7b/fb57412df8091de10000000a155106/content.htm

To Refresh a node, read the context and use clear or refresh on that work area or table and then bind it again. or use node_invalidate method.
