Empty table & lead selection

Hi folks,
We are having a small problem with our new web dynpro application. Basically we have table, which is populated when the application is started. Under the table we have "detail area", and it shows more detailed information about the selected element in the table. This works basically without problems.
The problems appear when the table happens to be empty. In that situation we got a runtime error saying "Context binding for property VALUE of <attribute name> cannot be resolved: Node <context node> does not contain any elements".
We have also functionality to delete elements in the table, and this causes the same problem. Even if the table contains elements, but we delete those, then when the last element gets deleted, we got the runtime error.
How to handle this kind of situation? My guess is that the lead selection functionality is causing the problem. If the table is empty, no element can be set as selected.
The cardinality of the relevant context node is 0...n, and selection 0...1.
Regards,
Karri

Hi Niraja,
I am displaying data from 2 tables VBAK & VBAP. Depending up on the lead selection in VBAK am filling the data in VBAP. I can delete all the records from first table & still not end up in any error. I will try explain my procedure to you.
Below are the properties for my 2 context nodes:
VBAK:
Cardinality : 0..n
Selection : 0..n
Initialization Lead Selection: Unchecked
Singleton:   No
VBAP:
Cardinality : 0..n
Selection : 0..1
Initialization Lead Selection: Checked
Singleton:   Yes
Supply Function: SUPPLY_FETCH_VBAP_DATA
The 2 tables have the following properties set:
selectionChangeBehaviour : Auto
selectionMode: Auto
As you can see by default the leadSelection isn't set for the 1st table. But as soon as the user selects any record the leadSelection is set & the corresponding data is fetched into the 2nd table element.
METHOD supply_fetch_vbap_data .
DATA: ls_vbak TYPE ig_componentcontroller=>element_vbak,
        lt_vbap TYPE ig_componentcontroller=>elements_vbap.
CALL METHOD parent_element->get_static_attributes
    IMPORTING
      static_attributes = ls_vbak.
SELECT * FROM vbap INTO TABLE lt_vbap WHERE vbeln = ls_vbak-vbeln.
node->bind_table( new_items = lt_vbap ).
ENDMETHOD.
The user first enters a customer number & the corresponding orders are fetched from VBAK & bound to the first table. Below is the coding for the buttons action handler:
METHOD onactionfetch .
DATA : wd_node   TYPE REF TO if_wd_context_node,
         it_vbak TYPE ig_componentcontroller=>elements_vbak,
         lv_kunnr TYPE ig_componentcontroller=>element_vbak-kunnr.
wd_node = wd_context->get_child_node( name = 'PARENT1' ).
CALL METHOD wd_node->get_attribute
    EXPORTING
      name = 'KUNNR'
    IMPORTING
      value = lv_kunnr.
wd_node = wd_context->get_child_node( name = 'VBAK' ).
SELECT * FROM vbak INTO TABLE it_vbak WHERE kunnr = lv_kunnr.
IF sy-subrc EQ 0.
    wd_node->bind_table( new_items = it_vbak ).
ELSE.
ENDIF.
ENDMETHOD.

Bind Table / Lead Selection

Is there a way to bind a table without changing the lead selection? I know that I can read the lead selection before binding, and then set it after binding, but was wondering if there was a better way.

As far as i know there is no such ready made method or api available. As you already pointed out , you need to do that with programmatic.

Table lead selection

Hi Colleagues,
Here is the problem with tables selection
Depending upon the node size in the context i.e. if the nof elements is 4 i am displaying 4 tables in the output, where each table has three culms and one row containing test, text and Button elements
on click of button i am triggering an action which should display some other attributes of the particular node element(i.e. filesize, filename,title etc)
here my output has three tables where on click of the button in any table it is displaying the same element values
*on action of the button i have coded this*
public void onActionGetThesecuritydetails(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
String URL = wdContext.currentElementsElement().getURL();
String Filename = wdContext.nodeElements().getCurrentElement().getAttributeAsText("fileName");
but on click of buttons in the tables i am getting the same output (which should not be same)
i think on click of button that particular tgable element needs to selected and this should be sent to the action and we have to get that element attributes
could anyone help me how to achieve this?
Thanks & Regards
Swetha

Hi,
Thanks a lot for all your replies.I have got a solution for this
i.e i am passing parameters along with the action using
mappingOfOnAction.setString()
//Create column3
IWDTableColumn column2 = (IWDTableColumn) view.createElement(IWDTableColumn.class, null);
table.addColumn(column2);
//Create 3rdst TableCellEditor and bind it to an attribute of the Elements node in the context
IWDButton editor2 = (IWDButton) view.createElement(IWDButton.class, null);
IWDTextAccessor textAccessor = wdComponentAPI.getTextAccessor();
String lViewText = textAccessor.getText("install");
editor2.setText(lViewText);
IWDAction thisAction = view.getAction("GetThesecuritydetails");
IWDGridData celleditor2 = editor2.createLayoutData(IWDGridData.class);
celleditor2.setVAlign(WDCellVAlign.MIDDLE);
celleditor2.setPaddingTop("100px");
editor2.setOnAction(thisAction);
*editor2.mappingOfOnAction().setString("filename", element2.getFileName());*
   *editor2.mappingOfOnAction().setString("displayurl", element2.getURL());*
*editor2.mappingOfOnAction().setString("token", element2.getURLLabel());*
editor2.setVisible(IWDUIElement.DEFAULT_VISIBLE.VISIBLE);
editor2.setEnabled(true);
column2.setHAlign(WDTableColumnHAlign.CENTER);
column2.setTableCellEditor(editor2);
column2.setWidth("20%");
So i am getting the exact element details on click of action and in the action i am able to get them without using any context related coding
public void onActionGetThesecuritydetails(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, java.lang.String filename, java.lang.String token, java.lang.String displayurl )
    //@@begin onActionGetThesecuritydetails(ServerEvent)
       String file = filename;
        String finalurl = displayurl;
        String title = token;
Thanks & Regards

How to get list of block identifiers in a empty table and an empty index

We have an application that has issue with ITL waits: this application is running many INSERT statements on a table that has 2 NUMBER columns and one primary key index. The application is designed to run INSERT statements but they are never committed (this is a software package).
To check what are the really allocated ITL slots, I know that I can dump data block but I don't know how to get the block identifiers/numbers for an "empty" table and an "empty" index. Does someone knows how to do that ?
PS: I already had a look to the Metalink notes and I have a Metalink SR for that but maybe OTN forum is faster ?

You should be able to find the first data/index block with the following, even on an empty table/index.
select header_file, header_block +1
from dba_segments
where segment_name = '<index or table name>';

You only have only one option in the DDI to display in the example. when you have multiple values
i assume that by adding an empty row like this will lose the SELECTION MADE in DDI. (Correct me If i am wrong)
somehow i believe that we need to bind the DD values using SET LEAD SELECTION INDEX METHOD FOR THE DDI when they are already selected and trying to BIND.
*LO_ND_DETAILS->GET_STATIC_ATTRIBUTES_TABLE(*
      *importing TABLE = LT_DETAILS ).*
** Append an empty row to lt_details*
    *append LS_DETAILS to LT_DETAILS.*
    *LO_ND_DETAILS->BIND_TABLE(*
    *NEW_ITEMS = LT_DETAILS ).*
even though the above code will have the selected value, the SELECTIONS MADE will be initialize.
you need to bind it explicitly.
you have to create an element and bind the DDI values for adding an row as SARAVANAN said.
or i guess you can continue with you code but need to use SET LEAD to display the correct SELECTIONS MADE
loop at LT_DETAILS into LS_DETAILS.
      LV_TABIX = SY-TABIX.
      LR_ELEMENT = LO_ND_DETAILS->GET_ELEMENT( LV_TABIX ).
      WD_NODE = LR_ELEMENT->GET_CHILD_NODE( 'ACTIVITY_TYPES' ).
      WD_NODE->BIND_TABLE( NEW_ITEMS = LT_ACTIVITY_TYPES ). " data for dropdown
*" try to set the desired value in the DDI when you have multiple values using SET LEAD*
    endloop.

Hi ,
The onclick event provides you with a standard paramater "CONTEXT_ELEMENT" which has the element from which the event is triggered.
so you can declare this in the handler(if it is not there) and use it as follows.
CONTEXT_ELEMENT TYPE REF TO IF_WD_CONTEXT_ELEMENT an importing paramater.
DATA:
NODE_MODULE TYPE REF TO IF_WD_CONTEXT_NODE,
ELEM_MODULE TYPE REF TO IF_WD_CONTEXT_ELEMENT,
STRU_MODULE TYPE IF_V_MODULE=>ELEMENT_MODULE .
data itab TYPE TABLE OF zac_modules.
CONTEXT_ELEMENT->GET_STATIC_ATTRIBUTES(
IMPORTING
STATIC_ATTRIBUTES = STRU_MODULE ). "Using the context_element paramater to get the static attributes.
NODE_MODULE->GET_STATIC_ATTRIBUTES_TABLE(
IMPORTING
TABLE = itab )   "getting all the data.
DELETE itab WHERE zmodule_id = STRU_MODULE-zmodule_id. "deleting the particular row from the table and binding it.
CALL METHOD NODE_MODULE->BIND_TABLE
EXPORTING
NEW_ITEMS = itab
* SET_INITIAL_ELEMENTS = ABAP_TRUE

Lead Selection to be disabled for some of the records in Table

Hi ,
I have 5 records in table .User shouldn't be allowed to select four rows thosse four rows should be in disable mode just for display purpose.Only one Row must be allowed to select(lead select).
How can I Achieve above Functionality.
Thanks & Regards
Kiran

Hi Kiran,
Probably you might have tried the following.
Bind OnLeadSelect event to some action.
And in that action method write the code to fetch selected lead and check if it is 0(first row) else set leadselection to 0
int selectedRow = wdContext.node<node name>().getLeadSelection();
if(selectedRow!=0)
wdContext.node<node name>().setLeadSelection(0);
With this code the user can not select any of the rows other than first.
If this is not what u require please let me know

How to remove lead selection in table dynamically

I have a table in webdynpro which allows multiple selections of row. I have a button which is supposed to be clicked after selecting single or multiple rows. After clicking on the button I want to remove the lead selection of the selected rows (which is shown in golden color for each selected row) .
I tried REMOVE_SELECTED ELEMENTS and it works fine but only if i select the row by pressing CTRL. If i had selected a single row by just a mouse click (without ctrl) then it wont work.
THANKS

Hallo Amber,
If_wd_context_node has static attribute no_selection. use that to clear the lead_selection_index.
node->set-lead_selection_index( if_wd_context_node=>no_selection ).

Disable Lead selection for table row cloumn

HI Team,
I have table with multiple rows and multiple columns.
Based on the lead selection of the row we are displaying the some form.
But in table row there are some columns like enter date, when the user is trying to enter the date, it displaying the form because of lead selection and it is not allowing the user to enter the date.
So, I want disable the lead selection for some columns.
How can I do this?
Regards,
BAla

Hi
I think that you can get the UI Table in the wdDoModifyView method, and then the UI Column and play with his values, is something like this:
IWDTable table =(IWDTable)view.getElement( ");
And then play with the "column" methods.

The return value of sqlcode when select an empty table in a proc code

Table: test
there is an empty table. But when I use "select * from test" in a proc code, I found the return value of sqlca.sqlcode is 0, not 1403 (NO MORE DATA). Why ?

EXEC SQL DECLARE individual_cursor CURSOR for
               SELECT IATA_C, DELAY, UPDATE_TIME
               FROM TBL_TIME
               WHERE IATA_C <> '***' AND
                    FLAG = 1;
EXEC SQL OPEN individual_cursor;
while(1) {
printf("in while");
     if (sqlca.sqlcode == 1403 && individual_flag == 0) {
printf("no any data");
          return 1;
     } else if (sqlca.sqlcode == SQLNOMORE) {
          break;
     EXEC SQL FETCH individual_without_general_cursor INTO :pnrtime.airline, :pnrtime.delay, :pnrtime.update_time;
EXEC SQL CLOSE individual_cursor;
The result is:
in while
in while
no any data
Since the table is empty, why "in while" is printed twice? And "no any data" is printed in the end? I cannot decide the empty when using "select ... into" in proc unless using "select count(*) from test", right? Thx.

Table: show the line of lead selection

Hello,
I have a table with 691 lines, showing 20 lines per page. Is it possible to change the lead selection for example to line 60 and also jump to line 60. So that the table automatically shows the 3rd page with the line 60 - 80.
I can change the lead selection with:
node_trefferliste->set_lead_selection_index( index = 60 ).
Lead selection is set correctly to 60 but the table still shows the lines 1- 20.
best regards
Stefan

Hi Stefan,
What ever you have done is correct. One thing you need to change is whenever you change the lead selection for you table you need to scroll ALV also. For that get the lead selected entry and set it as frst_visible_row for you ALV table. Please do this coding in the respective view controller method WDDOMODIFYVIEW(). so that you will get exact result what you are expecting.
I hope i make you clear.
Warm Regards,
Vijay
