Error by binding a table to context node

Hello Experts,
If I try to bind a table of strings, there comes the error:
"Dynamic type conflict during the assignment of references."
Here is my coding:
METHOD fill_cssref_data .
"Stores the references to the css
DATA: lt_cssref TYPE TABLE OF string,
        wb_cssref LIKE LINE OF lt_cssref.
DATA: lo_nd_cssref TYPE REF TO if_wd_context_node.
DATA: wb_messages LIKE LINE OF lt_messages.
lo_nd_cssref = wd_context->get_child_node( wd_this->wdctx_cssref_data ).
LOOP AT lt_messages INTO wb_messages.
    CONCATENATE 'https://gtp.wdf.sap.corp/sap/bc/webdynpro/qce/msg_gui_edit?sap-language=E&csinsta='
                  wb_messages-installno '&mnumm=' wb_messages-problemno '&myear=' wb_messages-pyear
    INTO wb_cssref.
    APPEND wb_cssref TO lt_cssref.
ENDLOOP.
lo_nd_cssref->bind_table( lt_cssref ).
endmethod.
The node "CSSREF_DATA" contains just one attribute "CSSREF" type string, so I don't know why there's a problem binding a table of strings to this node.
I also tried the method "lo_nd_cssref->bind_elements( lt_cssref )", but the result was the same.
Does anybody know where my mistake is?
Best regards,
Lennart

Hello,
the problem was, that the string table had not the same name as the context node.
Best regards,

How to create a table type context node

Hi,
I am trying to create table type context node. While creating, in the wizard no where I can see the option for this.
Could you please let me know how can I do this?
In one standard component: SRQM_INCIDENT_H, I can see multiple table type context nodes. Not sure how and why?
Thanks,
Sandeep

HI Sandeep,
When you right click on context node and create , a wizard will open. In that Wizard in one sreen it will ask for type of view. There you have to select Table View.

Hii.. Here is the short dump.
Runtime Errors         OBJECTS_OBJREF_NOT_ASSIGNED_NO
Exception              CX_SY_REF_IS_INITIAL
Date and Time          07.04.2007 16:43:21
Short text
Access via 'NULL' object reference not possible.
What happened?
Error in the ABAP Application Program
The current ABAP program "/1BCWDY/0NMKGBOSP2TIV65B1I11==CP" had to be
terminated because it has
come across a statement that unfortunately cannot be executed.
What can you do?
Note down which actions and inputs caused the error.
To process the problem further, contact you SAP system
administrator.
Using Transaction ST22 for ABAP Dump Analysis, you can look
at and manage termination messages, and you can also
keep them for a long time.
Error analysis
An exception occurred that is explained in detail below.
The exception, which is assigned to class 'CX_SY_REF_IS_INITIAL', was not
caught in
procedure "HANDLEDEFAULT" "(METHOD)", nor was it propagated by a RAISING
clause.
Since the caller of the procedure could not have anticipated that the
exception would occur, the current program is terminated.
The reason for the exception is:
You attempted to use a 'NULL' object reference (points to 'nothing')
access a component.
An object reference must point to an object (an instance of a class)
before it can be used to access components.
Either the reference was never set or it was set to 'NULL' using the
CLEAR statement.
How to correct the error
Probably the only way to eliminate the error is to correct the program.
If the error occures in a non-modified SAP program, you may be able to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the following
keywords:
"OBJECTS_OBJREF_NOT_ASSIGNED_NO" "CX_SY_REF_IS_INITIAL"
"/1BCWDY/0NMKGBOSP2TIV65B1I11==CP" or "/1BCWDY/B_0NMLUIVDHGPOBAS29YIF"
"HANDLEDEFAULT"
If you cannot solve the problem yourself and want to send an error
notification to SAP, include the following information:
1. The description of the current problem (short dump)
To save the description, choose "System->List->Save->Local File
(Unconverted)".
2. Corresponding system log
Display the system log by calling transaction SM21.
Restrict the time interval to 10 minutes before and five minutes
after the short dump. Then choose "System->List->Save->Local File
(Unconverted)".
3. If the problem occurs in a problem of your own or a modified SAP
program: The source code of the program
In the editor, choose "Utilities->More
Utilities->Upload/Download->Download".
4. Details about the conditions under which the error occurred or which
actions and input led to the error.
The exception must either be prevented, caught within proedure
"HANDLEDEFAULT" "(METHOD)", or its possible occurrence must be declared in the
RAISING clause of the procedure.
To prevent the exception, note the following:

Error while genetrating gettter method on Context node attribute

Hi,
I am working in SAP CRM 7.0 Ehp1.Now I need to create get_p_a and set_p_a method
on context node attribute.But while selecting attribute and clicking on right and selecting
on generate P-Getter,getting an error (error message - View not copied or enhanced with wizard; processing not possible).
This is a custom context node attribute and need to create gettter,setter method.
Kindly assist on this or suggest is there any way to create method on required context node attribute.
Regards
Viren

Hi there,
Creation of Getter Setter is not possible for the AET Generated Views and Components.
It seems your view is generated using AET Table enhancement feature of Ehp1 and the context node is thus a based on a Z BOL object created by a feature of AET of Ehp1
For such context node, generation of getter setters is not possible with right click.
If you need any of GET_ , SET_, GET_P_ or GET_V , then you need to copy the GET_P_XYZ etc method you find on context node class.
Hope this helps
Thanks & Regards
Suchita

Is it possible to bind the elments with context node dynamically?

Hi All,
Is it possible to dynamically bind elements with context nodes?
In other words, at runtime, can we change the binding of an Inputfield to another context. Or a table to programmatically bind to another table?
Regards,
urbashi

hi urbashi.......
      it is possible..
       you should first pass the id of he ui element and then bind it.
       for ex:
         if there is an input field, you can get the attribute that is bound, using cl_wd_input_field->bound_value.
         if you want to set an attribute, use cl_wd_input_field->bind_value.
         the first one will give an idea of how a valueshould be given.

How to bind UI Element with Context Node Attribute Element

Hi,
I'm building my view dynamically in the wdDoModifyView method.
Is it possible to bind a "TextView" element to a specific element of an attribute node?
Scenario:
Node_Employees
|
+- Attribute_Code
|
+- Attribute_Name
Node Contents:
Employees
|
+- Code: 1, Name: Employee 1
|
+- Code: 2, Name: Employee 2
|
+- Code: 3, Name: Employee 3
I need to do something like binding a TextView UI element to the "Name" attribute of the element #2, what would result to show "Employee 2" on my view.
How can I do this?
Thanks in advance,
Geraldo.

Hi Saravanan,
First I populate the context node and it won't change during view's lifecycle. After that, I build my view and bind the TextView UI elements to the node context attributes elements.
If the node has 10 elements, I will build 10 TextView UI elements and bind them to each attribute element.
Regards,
Geraldo Brígido.

Error "Lead selection not set for context node"

Hi everyone,
I've got a Tree control in WebDynpro ABAP and I've implemented an "expand all" button.
Here's the coding:
METHOD expand_node_rec.

DATA lo_node_children TYPE wdr_context_child_map.
DATA wa_lo_node_children LIKE LINE OF lo_node_children.

    lo_nd_child = wa_lo_node_children-node.
    me->expand_node_rec( node = lo_nd_child ).
ENDLOOP.
ENDMETHOD.
However I'm getting the error above: "Lead selection not set for context node".
Any suggestions?
Edited by: DEVELOPMENT THEMIS on Jul 7, 2011 6:34 PM

hi developement Themis,
I think u didn't diclare "node" as context node. So declare it as a context node before using as a context node..as below
DATA node TYPE REF TO if_wd_context_node.
or u can use "lo_nd_child " as ur context node in ur program in place of "node"
then I think this error will be removed.
thanks,

Error while retrieving data from a context node

Hello All,
I am trying to get the value that will be slected in status field(drop down) of opportunity page.
lr_bt ?= me->typed_context->BTSTATUSs->collection_wrapper->get_current( ).
CHECK lr_bt is bound.
CALL METHOD lr_ent->get_property_as_string(
    EXPORTING
      iv_attr_name = 'ACT_STATUS'
      RECEIVING
      rv_result     = lv_status ).
On execution i am getting error in web ui. The error states that ACT_STATUS cannot be used. Is it because the status is a dropdown? Kindly help on this.
Regards
Chandrakant

Hi,
Thanks bhusan and Lakshmi.
@bhushan : i had used STATUS in my code. But one s got added by mistake while copying and editing here.
As suggested by Lakshmi the error was that. I could fix the issue. However i am not able to get any value in lv_status.
I have defined lv_status as string. and i am coding in do_prepare_output.
how could i know the type of values that status has?? Do i need to use get_property_text?
Please help on this.

ABAP: dynamic context node + attribute for DROP_DOWN_BY_KEY

Hello,
I need to create a Node with attributes dynamically and than assign it to a DROP_DOW_BY_KEY element in ABAP.
I create drop down this way:
drop_down_figure = cl_wd_dropdown_by_key=>new_dropdown_by_key( bind_selected_key = 'REPOSITORY.FIGURES' on_select = 'GET_OPERATOR' ).
cl_wd_grid_data=>new_grid_data( element = drop_down_figure ).
ui_container->add_child( drop_down_figure ).
However, here I bind to REPOSITORY.FIGURES. Instead of doing this I need to bind it to an attribute that I create.
I can access wd_context but I am not sure how to create a node in wd_context, then attribute for that node that will contain items for drop down.
bind_selected_key is type of String. If I create a node with attribute how do I cast it to a String so I can pass it to a constructor of a drop down?
Thank you.

Bind Dynamic Table To a Context Node

Hello,
I created an internal dynamic Table. I want to show this table in an ALV-Table. So I want to bind it to a context node.
I create the context node attributes by this:
lr_node_info ?= lo_nd_template_exp->get_node_info( ).
*Type of table type and context type have to be the same
LOOP AT lt_plchar INTO ls_plchar.
clear lv_text.
lv_text = ls_plchar-plchar.
TRANSLATE lv_text TO UPPER CASE.
ls_fieldcatalog-fieldname = lv_text.
ls_fieldcatalog-inttype = 'C'.
ls_fieldcatalog-intlen   = '10'.
APPEND ls_fieldcatalog TO lt_fieldcatalog.
ls_attribute-name = lv_text.
ls_attribute-type_name = 'CHAR10'.
lr_node_info->add_attribute( EXPORTING attribute_info = ls_attribute ).
ENDLOOP.
So I create a fieldcatalog and the attributes at once.
Then I generate the table with this:
CALL METHOD cl_alv_table_create=>create_dynamic_table
       EXPORTING
         it_fieldcatalog = lt_fieldcatalog
       IMPORTING
         ep_table = <fs_data>
       EXCEPTIONS
         generate_subpool_dir_full = 1
         OTHERS = 2 .
IF sy-subrc <> 0.
ENDIF.
* So now points to our dynamic internal table.
ASSIGN <fs_data>->* TO <fs_1>.
* Next step is to create a work area for our dynamic internal table.
CREATE DATA new_line LIKE LINE OF <fs_1>.
* A field-symbol to access that work area
ASSIGN new_line->* TO <new_line>.
Data: copy_table type ref to data.
field-symbols: <copy_table> type standard table.
create data copy_table like table of <new_line>.
assign copy_table->* to <copy_table>.
ok, nice. when i now bind the table to <copy_table> to lo_nd_template_exp it all works fine. But i also want to but the data into the table.
This also works. When I debug, I can see the table filled with the values. But then there's always this error:
Invalid operand type for the MOVE-CORRESPONDING statement.
Ok, I have read, that the types may be not fit. But I don't know why and how i can solve it.
Do you have any ideas?

Hi,
I've the same problem: I must create all attribute of my node at run-time and then create alv.
I use the method:
DATA lo_cmp_usage TYPE REF TO if_wd_component_usage.
DATA lo_interfacecontroller TYPE REF TO iwci_salv_wd_table .
lo_cmp_usage =   wd_this->wd_cpuse_alv( ).
IF lo_cmp_usage->has_active_component( ) IS INITIAL.
    lo_cmp_usage->create_component( ).
ENDIF.
Pass context node to ALV
lo_interfacecontroller =   wd_this->wd_cpifc_alv( ).
lo_interfacecontroller->set_data( node_lenght ). " node_lenght is my dynamic node
But I receive this message error:
Invalid operand type for the MOVE-CORRESPONDING statement.

How to map XML to Web Dynpro context nodes?

Hi All,
Could anyone tell how xml string can be bound to context nodes ? In my requirement i need to serialize context nodes value to string and deserialize it back to nodes for implementing back naviagtion between views.
I didnt see much threads achieving this giving details on class cl_wdr_xml_convert_util and methods if_wd_client_conversion_util~string_to_struct.
I am using wd_context->to_xml to convert into xml.
From this format, i want to bind it back to context node.
When i use this below approch i get short dumb.
Serialization to xml:
lv_data_string = wd_context->to_xml( ).
Deserialization:
DATA lv_typedescr           TYPE REF TO cl_abap_typedescr.
FIELD-SYMBOLS:
                 <fs_data>    TYPE ANY TABLE.
CALL METHOD cl_abap_typedescr=>describe_by_object_ref
    EXPORTING
      p_object_ref         = wd_context
    RECEIVING
      p_descr_ref          = lv_typedescr
    EXCEPTIONS
      reference_is_initial = 1
      OTHERS               = 2.
   try.
CALL METHOD cl_wdr_xml_convert_util=>if_wd_client_conversion_util~string_to_struct
    EXPORTING
      in            = lv_data_string
      typedescr = lv_typedescr
    IMPORTING
      data      = <fs_data>
CATCH cx_wdr_conversion_exception into lo_err .
lv_exp = lo_err->get_text( ).
ENDTRY.
wd_context->bind_table( values = <fs-data>.
Using this way, i get a short dumb as assert statement is failed as value for typedescr->type_kind is '*'.
method if_wd_client_conversion_util~string_to_struct.
assert typedescr->type_kind = cl_abap_typedescr=>typekind_struct1
      or typedescr->type_kind = cl_abap_typedescr=>typekind_struct2.
raise exception type cx_wdr_conversion_exception
    exporting textid = cx_wdr_conversion_exception=>illegal_type.
On debugging changing this value to required also made no difference, as no value could be assigned to the field symbol.
Suggest a soution to do this.

Hi Thomas,
Thanks for your replies.
I have corrected it, but the field symbol is empty and while debugging it says data type is incorrect.
code:
FIELD-SYMBOLS:
                 <fs_data>    TYPE ANY TABLE.
data:       lsbp type ZXBPCENTRAL,
               go_ref type ref to data.
CALL METHOD cl_abap_typedescr=>describe_by_data " ( before it was describe_by_object_ref)
EXPORTING
p_data = lsbp
receiving
p_descr_ref = lv_typedescr.
try.
CALL METHOD cl_wdr_xml_convert_util=>if_wd_client_conversion_util~string_to_struct
EXPORTING
in = lv_data_string
typedescr = lv_typedescr
IMPORTING
data = go_ref "<fs_data>
CATCH cx_wdr_conversion_exception into lo_err .
lv_exp = lo_err->get_text( ).------> Here the error says " Invalid data type and hence, there is no data.
ENDTRY.
assign go_ref->* to <fs_data>.
I am still looking for solution and thanks a lot ....

How to populate the context nodes based on an event

Hi All,
I am having a basic problem. I have created a new Webdynpro Abap application. Here, in the main view, i have define a text view as well as a table. I have created context nodes A and B in component controller. The attributes under A are A1 and the attributes of B are B1,B2, and B3. I have also created an action button C in the same view. These have been mapped to the context nodes in the main view. A1 is mapped to the text view and B1, B2 and B3 are mapped to the table.
My requirement is as follows. When user Clicks on execute, i want to use the value A1 from the text view in a function module and return the values to B1, B2 and B3. B1, B2 and B3 are multiple values mind you.
I have successfully executed the function module within the WDONACTIONC method. How to i accomplish this Basic Task. Please Help
Best Regards
Mazin

Hi Mazin,
Step 3 is as follows...
Say you have a context node, you have to bind this node with table UI element, now this node must contain some context attribute which you have to bind with your columns of table. now say name of context node is cn_table. now what you have to do is get data from FM in the internal table..........
now move data by using move corresponding or by looping depending on requirement to an internal table which has fields with the same name as that of name of your attributes... this is imp to display the data...... now you can bind this internal table with context node using code below.......
data lo_nd_cn_table type ref to if_wd_context_node.
data lo_el_cn_table type ref to if_wd_context_element.

Sort table columns in a table and context created dinamically

Hello all,
I have implemented the table sorting several times in another developments, but now I'm facing a problem.
I have created the table and context node that I need to sort dinamically (before somebody ask me why, I would say that it's the only way to do that for my current project, there was no possibility of doing that in dessign time). I have implemented the table sorting more or less the same way I would do with a table created in dessing time, but when I run my WD the sorting of columns doesn't work.
In the wdDoModifyView, I have put the following code:
if(firstTime){
IWDAction ordenacion     = wdThis.wdCreateAction(IPrivateResultDispGlobalView.WDActionEventHandler.ORDENACION, null);
IWDParameters param = ordenacion.getActionParameters();
param.addParameter("nombreNodo",nombreNodo);
and in the code of the action
    //@@begin onActionOrdenacion(ServerEvent)
     System.err.println("**** NOMBRE NODO **** "+nombreNodo);
     wdContext.currentContextElement().getTableSorter().sort(wdEvent, wdContext.getChildNode(nombreNodo, IWDNode.LEAD_SELECTION));
    //@@end
The name of the node ("nombreNodo) it's only correct the first time I click on a column.
Has anybody implemented the table sorting in a dinamically created table and context node? And how do you do to make it works.
Thank you very much

Here is the code
//Preparamos Navegaciones
IWDAction abrirProyecto = wdThis.wdCreateAction(IPrivateResultDispGlobalView.WDActionEventHandler.ABRIR_PROYECTO, null);
IWDAction abrirDisp     = wdThis.wdCreateAction(IPrivateResultDispGlobalView.WDActionEventHandler.ABRIR_DISPONIBLE, null);
//IWDAction ordenacion     = wdThis.wdCreateAction(IPrivateResultDispGlobalView.WDActionEventHandler.ORDENACION, null);
IWDAction ordenacion=wdThis.wdGetOrdenacionAction();
IWDParameters param = ordenacion.getActionParameters();
param.addParameter("nombreNodo",nombreNodo);
IWDTable table = wdThis.wdGetInformesController().crearTabla(view, nombreNodo, movimientosInfo,new String[]{"Codi Projecte",null,"Nom Projecte", "Import Projecte", "Client", "Increment Disponible futur per facturació no emesa i / o anualitats pendents","Increment Disponible futur per ingressos pendents de cobrar", "Disponible"},new String[]{"10px", null,"10px", "10px","10px","10px","10px","10px"},new IWDAction[]{abrirProyecto,null, null, null, null,null,null,abrirDisp}, -1);
//ordenar tabla
wdContext.currentContextElement().setTableSorter(new TableSorter(table, ordenacion,null));
containerTablasProyecto.addChild(table);

How to update a webdynpro context node from flex ?

Hi
I have an table in webdynpro and a datagrid in flex, both getting the value from the same context node. My requirement is to make the table fields editable and when I make changes in the datagrid, it should get reflected back in the webdynpro table.
So how can I access the internal table's context node from flex ?
Can anyone help me with this.

Hi,
As you are using a datasource, i assume you have set method in flex to read the datasource(context node). What you need to do is store the reference to this datasource in a local flex variable. Have a look at the below code:
private var refreshFlexUINode:ArrayCollection;
public function set refreshFlexUI(datasource:ArrayCollection):void
refreshFlexUINode=datasource;
and say you want to edit one row of the table, get that row from ArrayCollection and assign the new value.
it would be like, if you want to save second row of the datagrid
Object obj = refreshFlexUI.getItemAt(1)
obj[<CONTEXT_ATTR_NAME>]=<new value>
Hope this helps!
Best Regards,
Srilatha
