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

Stateless Within a stateless application any data retrieved within one page will be lost as soon as a new page is called, unless it is passed as a parameter.

Stateful

Within a stateful application data is retained in memory even when a new page is called. This makes it much easier to pass data between WDP pages but means more resources will be used inorder to store the data.

Performace

When wdp application launches press ( ctrl+alt+shft+p ) .It will give you whole information.

Refresh

What you mean by refresh ?

You can invalidate the node if it is binded by Supply function then supply function would be called.

data:     lo_nd_sflight      type ref to if_wd_context_node,   
   lt_sflight            type wd_this->elements_sflight.   
  lo_nd_sflight = wd_context->get_child_node( name = wd_this->wdctx_sflight ).   
  lo_nd_sflight->invalidate( ).   
  "Or you can bind a new table with data (original date )    
 lo_nd_sflight->bind_table( new_items = lt_sflight ).
