WD Compoenent - Non -Interactive form- Not displaying output

[Former Member]

Hi,

I am practicing this adobe form session [https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/media/uuid/a3e2f018-0b01-0010-c7a8-89deb6e63e97] from SDN.Unfortunately this session was not complete so I am trying to complete it.

In brief : this WD component accepts CARRID and displays output in PDF format.

I was able to capture selection and get respective entries for that selection in my internal table but my display is blank.Here is what I coded in Search Button..

method ONACTIONSEARCH .



    data: isflight type table of sflight.


    DATA lo_nd_adobe_data TYPE REF TO if_wd_context_node.
    DATA lo_el_adobe_data TYPE REF TO if_wd_context_element.


    DATA lo_nd_data_selections TYPE REF TO if_wd_context_node.
    DATA lo_el_data_selections TYPE REF TO if_wd_context_element.
    DATA ls_data_selections TYPE wd_this->element_data_selections.
* navigate from <CONTEXT> to <DATA_SELECTIONS> via lead selection
    lo_nd_data_selections = wd_context->get_child_node( name = wd_this->wdctx_data_selections ).

* get element via lead selection
    lo_el_data_selections = lo_nd_data_selections->get_element(  ).

* get all declared attributes
    lo_el_data_selections->get_static_attributes(
      IMPORTING
        static_attributes = ls_data_selections ).


* Retrieve that data from the database. Normally it is suggested to
* encapsulate the data retrieval in a separate class.
* For simplicity, the SELECT statement has been implemented here.
    clear isflight. refresh isflight.
    select * into corresponding fields of table isflight from sflight
    where carrid =  ls_data_selections.



* navigate from <CONTEXT> to <ADOBE_DATA> via lead selection
    lo_nd_adobe_data = wd_context->get_child_node( name = `ADOBE_DATA` ).
    lo_nd_adobe_data->bind_elements( isflight ).



endmethod.

endclass.

Anything wrong with my code..I am getting my data in isflight internal table.

FYI..I am throwing output as text field in adobe form.

Hi Vara,

See the problem is very clear, before binding the table with your context node you are clearing and refreshing the internal table and work area.... so first bind the table and thn do clear and refresh...

see the small change in your code....

select * into corresponding fields of table isflight from sflight
    where carrid =  ls_data_selections.
 
 
 
* navigate from <CONTEXT> to <ADOBE_DATA> via lead selection
    lo_nd_adobe_data = wd_context->get_child_node( name = `ADOBE_DATA` ).
    lo_nd_adobe_data->bind_elements( isflight ).

clear isflight. refresh isflight.

Hi Vara,

Pranav,

That is a interactive form tutorial.I just want display my contents .

eg: if I give Invoice number as input in my webdynpro it should output Invoice in pdf form.

Arjun,

I gone through that already but there is no internal table scenario.I am just confused on how do we show internal table contents ?

Hi Vara,

Try this code to set data in table

DATA lo_nd_cn_table TYPE REF TO if_wd_context_node.
  DATA lt_cn_table TYPE wd_this->elements_cn_table.

* navigate from <CONTEXT> to <CN_TABLE> via lead selection
  lo_nd_cn_table = wd_context->get_child_node( name = wd_this->wdctx_cn_table ).

  lo_nd_cn_table->bind_table( new_items = lt_cn_table set_initial_elements = abap_true ).

Pranav,

What is elements_cn_table?

I have a Context node called ADOBE_DATA and Inside in there are 2 subnodes SLFLIGHT & DATA_SELECTIONS.

So I tried

   clear isflight. refresh isflight.
    select * into corresponding fields of table isflight from sflight
    where carrid =  ls_data_selections.

DATA lo_nd_cn_table TYPE REF TO if_wd_context_node.
  DATA lt_cn_table TYPE wd_this->elements_sflight.

* navigate from <CONTEXT> to <CN_TABLE> via lead selection
  lo_nd_cn_table = wd_context->get_child_node( name = wd_this->wdctx_sflight ).

  lo_nd_cn_table->bind_table( new_items = lt_cn_table set_initial_elements = abap_true ).

I got this error..Subnode MAIN.SFLIGHT does not exist

Also,I am not understanding where are we binding our internal table ISFLIGHT ?

Since you have a sub node first you can directly set it this way you have to reach your sub node first...

and you can bind your sflight internal table here

cn_table is the name of my context node........

lo_nd_cn_table->bind_table( new_items = sflight set_initial_elements = abap_true ).

Pranav,

Thank you for your extensive help.

Your code helped in resolving the issue.

Hi Vara,

You can try BIND_TABLE method in the interface IF_WD_CONTEXT_NODE using the reference

lo_nd_adobe_data.

Just check with this and confirm.

Shasikanth,

I tried this

lo_nd_adobe_data->bind_table( isflight ).

it did not work either.While outputing data I just dragged and dropped 2 fields CARRID & CONNID from data view on to form.

I haven't changed any properties.This is like an input field.

Do you think that is causing the issue?

[pranav_nagpal2]

Are you having inputfields in your interactive form???

[Former Member]

Pranav,

My goal is to show the contents of the internal table(ISFLIGHT)

I was thinking as an example it would atleast throw first record in the input field.

If my thinking is wrong pls suggest how we can show internal table on form?

Right now i dont have Adobe 7.1 installed so i cant try it at my end, but here is a link from saptechnical in which they are getting data from adobe... now instead of getting data you have to set data.... this link might help you...

open sap technical and go this tutorial... i am not allowed to paste complete link here...

Hi Vara,

The code seems to be ok.

Did you paste this code in you wddomodifyview of the view where you have the interactive UI element.

data:

lr_interactive_form type ref to cl_wd_interactive_form,

lr_method_handler type ref to if_wd_iactive_form_method_hndl.

check first_time = abap_true.

lr_interactive_form ?= view->get_element('PDF1').

lr_method_handler ?= lr_interactive_form->_method_handler.

lr_method_handler->set_legacy_editing_enabled( abap_true ).

Here PDF1 is the name of the Interactive form UI element name in my scenario.

Hope it helps.

Good day!

Hi,

I have debugged my application.I see entries in my internal table isflight .

I think problem is in binding.

* navigate from <CONTEXT> to <ADOBE_DATA> via lead selection
    lo_nd_adobe_data = wd_context->get_child_node( name = `ADOBE_DATA` ).
    lo_nd_adobe_data->bind_elements( isflight ).

Shasikanth,

I also tried including code in WDDOMODIFYVIEW but it did not work either.

any idea what i am doing wrong?

Hi Vara,

Try this:

method ONACTIONSEARCH .
 
 
 
    data: isflight type table of sflight.
 
 
    DATA lo_nd_adobe_data TYPE REF TO if_wd_context_node.
    DATA lo_el_adobe_data TYPE REF TO if_wd_context_element.
 
 
    DATA lo_nd_data_selections TYPE REF TO if_wd_context_node.
    DATA lo_el_data_selections TYPE REF TO if_wd_context_element.
    DATA ls_data_selections TYPE wd_this->element_data_selections.
* navigate from <CONTEXT> to <DATA_SELECTIONS> via lead selection
    lo_nd_data_selections = wd_context->get_child_node( name = wd_this->wdctx_data_selections ).
 
* get element via lead selection
    lo_el_data_selections = lo_nd_data_selections->get_element(  ).
 
* get all declared attributes
    lo_el_data_selections->get_static_attributes(
      IMPORTING
        static_attributes = ls_data_selections ).
 
 
* Retrieve that data from the database. Normally it is suggested to
* encapsulate the data retrieval in a separate class.
* For simplicity, the SELECT statement has been implemented here.
*    clear isflight. refresh isflight.
    select * into corresponding fields of table isflight from sflight
    where carrid =  ls_data_selections-carrid.
 
 
 
* navigate from <CONTEXT> to <ADOBE_DATA> via lead selection
    lo_nd_adobe_data = wd_context->get_child_node( name = `ADOBE_DATA` ).
    lo_nd_adobe_data->bind_elements( isflight ).
 
 
 
endmethod.
 

I hope it helps.
