Bind_table

I know that there is a way to bind an internal table to a context node using the
method bind_table.
But I need to do the opposite. I need to populate an internal table with the elements
of a node. Is there an existing method I can use?

Hi,
To get the values binded to the table you can use method
get_static_attributes_table.
1.click on patter or CTRL+F6.
2.select call method.
enter class/interface as IF_WD_CONTEXT_NODE.
method :get_static_attributes_table.
CALL METHOD lo_nd_prf_exp_cer_detail->get_static_attributes_table
* EXPORTING
*    from   = 1
*    to     = 2147483647
      IMPORTING
        table = lt_prf_exp_cer_detail

Dynamic column Name# Contains Invalid Characters. Bind_table() fails

Hi WD experts,
I have tried to use the bind_table() on a dynamically generated table. Now it happens that this dynamic table contains columns like NAME# . This gave rise to a dump :
The Name NAME# Contains Invalid Characters. Valid Characters are A-Z, 0-9, _, and /.
Other tables which do not have such columns are correctly bound.
In my method , I first loop over the field catalog to retrieve some field names from a dynamicallt generated report...
LOOP AT lt_fieldcat_out INTO lwa_fieldcat.
    comp-name = lwa_fieldcat-fieldname.
    comp-type ?= cl_abap_typedescr=>DESCRIBE_BY_DATA( lwa_fieldcat-FIELDNAME ).
    APPEND comp TO comp_tab.
ENDLOOP.
structure which represents the dynamic table
struct_type = cl_abap_structdescr=>get(
                                          p_components = comp_tab
                                          p_strict = abap_FALSE   ).

                              is_static = abap_false
struct_type = node_info->GET_STATIC_ATTRIBUTES_TYPE( ).
Afterwards, I bind a dynamic table to the new node...
Do you have an idea how to circumvent this ?

Links not getting displayed in the contextual panel

Hi,
I have created a contextual panel inside a transparent container. And created a method in the same view supply_values of type supply function to supply the values to the panel.Inside the method I have coded like:
DATA TAB TYPE WD_THIS->ELEMENTS_N_VIEW_SWITCH.
DATA LINE TYPE WD_THIS->ELEMENT_N_VIEW_SWITCH.
LINE-TEXT = 'User Manual'. "#EC NOTEXT
LINE-ENABLED = ABAP_TRUE.
APPEND LINE TO TAB.
LINE-TEXT = 'Logout'. "#EC NOTEXT
LINE-ENABLED = ABAP_TRUE.
APPEND LINE TO TAB.
NODE->BIND_TABLE( TAB ).
Also in the context of the view I have created a node and supplied the method 'supply_values' in the supply function.Under the node I have 2 attributes named text and enabled. Text is of string type and enabled is of boolean type. In the properties of the contextual panel I have bound the visible property with the enabled attribute.
Now when I am running this application , links are not getting displayed in the contextual panel. Though when I debug TAB contains the values. Please suggest if I have missed out something or I need to look into the properties of the contextual panel. Any pointers will be really helpful.
Regards,
Ashutosh

Hi,
Can you elaborate ' ItemEnable property of ViewSwitch'.
I have already bound the enable property of the panel with a context attribute of type wdy_boolean but it is still not working.

How to create a node with attributes at runtime in webdynpro for ABAP?

Hi Experts,
         How to create a node with attributes at runtime in webdynpro for ABAP? What classes or interfaces I should use? Please provide some sample code.
I have checked IF_WD_CONTEXT_NODE_INFO and there is ADD_NEW_CHILD_NODE method. But this is not creating any node. I this this creates only a "node info" object.
I even check IF_WD_CONTEXT_NODE but i could not find any method that creates a node with attribute.
Please help!
Thanks

I am trying to create a new node. That is
CONTEXT
- DYNFLIGHT
CARRID
CONNID
As you see above I am trying to create 'DYNFLIGHT' along with the 2 attributes which are inside this node. The structure of the node that is, no.of attributes may vary based on some condition. Thats why I am trying to create a node dynamically.
Also I cannot define the structure in the ABAP dictionary because it changes based on condition

Error while binding data into Node which is Created Dynamically.

Hi All
We have a scenario , which is to create the Context and its attribute dynamically at runtime. When I create the context with structure. Using the method <b>create_nodeinfo_from_struct()</b>.here the attributes under the created node is automatically taken from the provided structure SPFLI.
cl_wd_dynamic_tool=>create_nodeinfo_from_struct(
parent_info = rootnode_info
node_name = DYN
structure_name = SPFLI
is_multiple = abap_true ).
Using the above method it is working fine and I could bind the value into the node.
But our scenario is to create context and its attributes without giving any predefined structure. We need to add attributes manually giving one by one.
For that I have used the method rootnode_info->add_new_child_node &
dyn_node->add_attribute( exporting attribute_info = ls_attribute ).
But am getting short dumb showing <b>Line types of an internal table and a work area not compatible.</b>

Hi Nojish.
I gues the error happens when you try to read the static attributes of an element of
you dynamic node. This does not work using your defined type str, cause with
get_static_attribute you only receive the static and not the dynamic attributes.
Static attributes are attributes that are defined at design time. Thats why the
structure does not match.
But you can use the following code to get your dynamic attributes, for example
getting the lead selection element and the attribute carrid:
dyn_node = wd_context->get_child_node( name = 'DYN' ).
lr_elelement = dyn_node->get_element( ).
lr_el->get_attribute(
    EXPORTING
      name = 'CARRID'
    IMPORTING
      value = lv_carrid
Hope this helps.
PS: Or do you get the reerror in above code? Your code works here. If so pls provide short dump.
Cheers,
Sascha

<fs_flow> is empty
but after I enter value and then press enter and then click the button to retrieve the values I am able to get low value <fs_flow> not the sign and option
Is it the standard functionality ,if yes how can we overcome

Unable to display table data in Review View

Hi Experts,
I have one main view and one review View .In my main view i have one table (Normal Table) and several other input feilds and text views....
If i click on review button in my main view, am able to see all the data in review view except table data.
How can i get the table data which i have entered in main view.. the same should display in review view.
I binded the same node in both main and review. and node is defined under component controller.
Any ideas?
Regards
Farooq.

Hi,
I think you already binded in review view also with same node. right? So data will move automatically and display in
review view also. In WDDOINIT of review veiw read data from that node and use bind_Table.
Cheers,
Kris.

Setting the value of a single attribute for multiple line items

Hi all,
I am working on a Web Dynpro application, I have created this applicaion for an accounting document so it has header data and multiple line item data. As per the requirement I have to put the following logic:
1. When a user enters a value in the field KBLNR on the line item, all the other fields like cost centerm fund, functional area should populate from a database table based on the value of the KBLNR. to get this I have put the following code:

ENDLOOP.
everything is working fine but now the problem is couple of fields that I have in wa_kblp are with different names in bseg table and hence they are not updating... I tried putting the following logic within the loop :
lo_el_t_bseg->set_attribute(
    name = `PROJK`
value = wa_kblp-pspnr ).
but it's only setting the value of the first line item and not working for the multiple line items, can you please tell me how can do this?
Thanks,
Rajat Garg

Hi Chris,
I tried your code and it worked fine but after I put this code I am getting another issue. within the loop I had a code to make the fields non modifiable on the screen and was working fine but now what's happening is it's making the all the lines uneditable except the one with data on it (which is completely opposite), this is what I have coded:
LOOP AT lt_el_tbseg INTO lo_el_tbseg.
    lo_el_tbseg->get_static_attributes(
                           IMPORTING static_attributes = lv_bseg ).

Not compatible with the formal parameter "NEW_ITEMS"

Dear,
I'm creating a very simple WD4A to just display the contents of the table.
So in the COMPONENTCONTROLLERS I created the node ZPI_USERS, according to the type of the internal table ZPI_USERS we have on the PI system.
Still in the COMPONENTCONTROLLER under methods I'm trying to implement this code in the 'wddoinit' event:
METHOD wddoinit.
DATA: lt_users    TYPE zpi_users,
        node_users TYPE wd_this->element_users,
        lo_nd_users TYPE REF TO if_wd_context_node,
        lo_el_users TYPE REF TO if_wd_context_element.
* navigate from <CONTEXT> to <USERS> via lead selection
lo_nd_users = wd_context->get_child_node( name = wd_this->wdctx_users ).
SELECT * FROM zpi_users
           INTO lt_users.
    lo_nd_users->bind_table( new_items = lt_users ).
ENDMETHOD.
On trying to activate I get the following error :
Web Dynpro Comp. / Intf. ZPI_DISPLAY_MONIUSERS,Web Dynpro Component Controller COMPONENTCONTROLLER
Method WDDOINIT
"LT_USERS" is not type-compatible with formal parameter "NEW_ITEMS".
I know I'm overseeing something very simple, though I get the feeling I'm running in circles. Again: the only thing I want to do is show an internal SAP table through a Web Dynpro.
Kind regards,

Hi,
You have declared
DATA: lt_users    TYPE zpi_users,
This means that you are declaring a work area and not an internal table, whereas while binding we need to pass an internal table.
Declare your table as follow,
DATA: lt_users    TYPE TABLE OF zpi_users.
" modify your select
    SELECT *
      FROM zpi_users
      INTO TABLE lt_users.
Hope this helps!

Hebrew fonts from drop-down box not displaying in text box.

I am using InDesign CS 5.5 on a Mac 10.8.4.
When in ID, the fonts I am seeing on the Font dropdown menu when I try to use in a text box are not displaying correctly. They only display as boxes. The fonts are in the Hebrew language. They are properly installed in the FontBook.
Please help!! Thank you.

Reema,
I followed most of your steps. I have a question reg. step 3 ie populating data in node 1.
Here is my code:
method WDDOINIT .
types: begin of zs,
zktokd type kna1-ktokd,
end of zs.
data: handle1 type ref to if_wd_context_node,
begin of zstruct,
zktokd type kna1-ktokd,
end of zstruct,
zitab type table of zs.
handle1 = wd_context->get_child_node( name = 'NODE1' ).
*select ktokd into corresponding fields of zstruct from kna1.
*append zstruct to zitab.
*endselect.
zstruct-zktokd = 'Sold-to party'.
append zstruct to zitab.
zstruct-zktokd = 'Goods recipient'.
append zstruct to zitab.
zstruct-zktokd = 'Payer'.
append zstruct to zitab.
zstruct-zktokd = 'Bill-to party'.
append zstruct to zitab.
zstruct-zktokd = 'Prospective Customer'.
append zstruct to zitab.
zstruct-zktokd = 'Competitor'.
append zstruct to zitab.
zstruct-zktokd = 'Sales partners'.
append zstruct to zitab.
zstruct-zktokd = 'Hierarchy Node'.
append zstruct to zitab.
zstruct-zktokd = 'Named List of Accounts'.
append zstruct to zitab.
zstruct-zktokd = 'Distribution center'.
append zstruct to zitab.
zstruct-zktokd = 'Payer'.
append zstruct to zitab.
handle1->bind_table( new_items = zitab ).
endmethod.
Please let me know if this is the best way to populate the node and then bind the table values from the node to the drop down box.
Thanks and Regards.

More fun with enumerated dropdowns - Binding to table

Hi All,
I'm having some trouble with enumerated dropdowns.
My context is as follows:
node DATA 1...1
---> node FLIGHTS 0...N
   -->CARRID etc from SFLIGHTS
--->DDL (element type string)
I have successfully tried to add a simple dropdown with the following code on the component controller:
method wddoinit .
    data lo_nd_data type ref to if_wd_context_node.
    data lo_el_data type ref to if_wd_context_element.
    data ls_data type wd_this->element_data.
    data lv_ddl like ls_data-ddl.
    data node_info type ref to if_wd_context_node_info.
    data vals type table of wdr_context_attr_value.
    data: s_element type wdr_context_attr_value.
    data: str type string.
*   navigate from <CONTEXT> to <DATA> via lead selection
    lo_nd_data = wd_context->get_child_node( name = wd_this->wdctx_data ).
*   get element via lead selection
    lo_el_data = lo_nd_data->get_element( ).
    lo_el_data->get_static_attributes(
      importing
        static_attributes = ls_data ).
*      get node info
    call method lo_nd_data->get_node_info
      receiving
        node_info = node_info.
     do 25 times.
       str = sy-index.
       condense str no-gaps.
       s_element-text = str.
       s_element-value = str.
       append s_element to vals.
    enddo.
*    Set Value_sets to node_info
     call method node_info->set_attribute_value_set
      exporting
        name      = 'DDL'
        value_set = vals
endmethod.
This works fine, however now I am trying the same thing with a field from the SFLIGHTS table.
I want to display a table of the retrieved SFLIGHTS but a field as a dropdown with valid entries from the database. I have added the following code to the view.
method WDDOINIT .
    data lo_nd_data type ref to if_wd_context_node.
    data lo_nd_flights type ref to if_wd_context_node.
    data lo_el_flights type ref to if_wd_context_element.
    data ls_flights type wd_this->element_flights.
    data gt_flights type table of sflights.
    select * from sflights into table gt_flights.
*   navigate from <CONTEXT> to <DATA> via lead selection
    lo_nd_data = wd_context->get_child_node( name = wd_this->wdctx_data ).
*   navigate from <DATA> to <FLIGHTS> via lead selection
    lo_nd_flights = lo_nd_data->get_child_node( name = wd_this->wdctx_flights ).
    lo_nd_flights->bind_table( gt_flights ).
       types: begin of ty_carrname,
     carrname type s_carrname,
     end of ty_carrname.
   data: gt_carrname type table of ty_carrname.
   select distinct carrname
      from sflights
      into table gt_carrname.
     data lv_carrname like ls_flights-carrname.
     data node_info type ref to if_wd_context_node_info.
     data vals type table of wdr_context_attr_value.
     data: s_element type wdr_context_attr_value.
     data: str type string.
      lo_nd_flights->get_static_attributes(
      importing
        static_attributes = ls_flights ).
      call method lo_nd_flights->get_node_info
      receiving
        node_info = node_info.
     field-symbols: <carrname> like line of gt_carrname.
     loop at gt_carrname assigning <carrname>.
       str = <carrname>-carrname.
       s_element-text = str.
       s_element-value = str.
       append s_element to vals.
     endloop.
     call method node_info->set_attribute_value_set
      exporting
        name      = 'CARRNAME'
        value_set = vals.
endmethod.
I can display all the entries with a repeating subform but when I bind the CARRNAME to an enumerated dropdown I get an ADS rendering error:
WebDynpro Exception: The ADS call has failed. You can find information about the cause in the error.pdf on the application server
I have looked in the Error PDF but it is blank.
Does anyone have any suggestions on what is goign wrong or how to diagnose the problem.
I am assuming you can have a data element that has a 0..N cardinality (i.e a table element) and is also of type enumerated dropdown.
I'm guessing this is something to do with cardinality but I have no way to find out.
Thanks,
Gregor

I have looked in the defaultTrace file and found the following errors:
1. A pdf document with 0 pages.
    Return Status: Render Failure
    Output Trace returned: <?xml version="1.0" encoding="UTF-8"?>
<log>
   <m mid="29184" tid="10064.4896" sev="f" d="2008-11-12T15:20:01.722Z">Malformed SOM expression: $record.sap-vhlist.FLIGHTS\\.DATA[*]\\.CARRNAME.item[*]</m></log>
Has anybody else used the enumerated dropdown element bound to dynamic data?
I am using the latest releases and the "Specify Item Values" on the Object->Binding tab is filled in with what looks correct ($record.sap-vhlist.FLIGHTS\.Data etc) but greyed out.
Thanks

Getting values from a domain

Hi!
When I enter fix values into a domain, it is appearing automatically through the data element in an element of a view (like a dropdown by key). That's nice, it is working perfectly.
However if I don't use fix values in the domain, but I use a value table, the table entries are not appearing automatically. Do I have to code it in the wddoinit, or is there an easier way for showing in the view's dropdown element, the values from the domain's value table?
Thank you
Tamá

Hi,
Just fetch data from your value table and bind it to the node. You can use dropdownbyindex.
Create a node; cardinality 0:n -> create an attribute ( keep the attribute name same as the field name of your value table; this will help reduce the coding )
Now use the follwing code;
Data: l_node type ref to if_wd_context_node.
Data: lt_values type wd_this->elements_nodename.
" fetch data from value table.
Select text " fieldname
from .............. into lt_values.
l_node = wd_context->get_child_node( 'NODENAME' ).
l_node->bind_table( lt_values ).
