Problem in accessing attribute of a context node

Hi All,
I have a context node called REFE and an attribute named REF to the node REFE. I am trying to get access to the attribute REF, so that i can dynamically set properties. But i am getting NULL Object error. I am successfully getting access to node REFE.
Here is the code.
lo_nd_refe = wd_context->get_child_node( name = wd_this->wdctx_refe ).
lo_el_refe = lo_nd_refe->get_element( ).
lo_el_refe->set_attribute(
      EXPORTING
        name = `REF`
        value = 'http://sapsndbp.sbic.co.za:8011/sap/bc/webdynpro/sap/zzdm_audit_report' ).

RAvi

Hi,
What is the cardinality of the node.
If it is 1:1 then you can get teh reference of the context element directly.
If it 0:N or 1:N then you need to pass the index of the context element you are trying to get.
Use the method get_element of the context node and pass the index value.
Always check the element is initial or not before you process further for better coding.

Lekha.

Access attribute of a context node in another context node of the same view

Hi all,
I want to acess value of an attribute PERNR of context node CUSTOMERS in another context node AUTHENTICATION of the same view. A sample syntax would be helpful .
Thanks,

You didn't specify your version of Oracle so here are two options. If 10.2 or greater, use XMLTable, else use the ExtractValue option.
-- The WITH simply simulates your existing table that I do not have.
WITH fake_tab AS
(SELECT XMLTYPE('<?xml version="1.0" encoding="ISO-8859-1"?>

<Setting Name="A6" Value="N"/>
</Settings>
') tab_col
FROM dual)
-- For 10.2 and higher use this SELECT
SELECT a5
FROM fake_tab,
 XMLTABLE('/Settings'
 PASSING fake_tab.tab_col
 COLUMNS
 a5 VARCHAR2(10) PATH 'Setting[@Name="A5"]/@Value');
-- For 10.1 and before
SELECT ExtractValue(tab_col, '/Settings/Setting[@Name="A5"]/@Value')

Reading Attributes from different context nodes in the same view

Hi,
I have added a new field as part of an enhancement for Trade Promotions. This field is a checkbox and part of the context node TRADE in the view TPMOE/HeaderEOF. This field will be checked or unchecked using a logic in the background.
The logic will be based on an attribute (Fund Plan ID) which is part of another context node FUNDPLAN in the same view.
How can I read the attribute of FUNDPLAN context node in TRADE context node?
A sample code will be quite helpful as I am new to CRM 2007.
Thanks,
Abhishek
Edited by: Abhishek Periwal on Oct 16, 2008 2:35 PM

Hi Abhishek,
If I understand your question correctly, you would like to access the Fund plan ID (in a different context node) in the getter setter methods of the check box attribute which you have added.
The code snippet mentioend by sudeep works perfectly fine when you are making any checks in the view implementation class. But since you are in the getter setter methods of the context class, this doesnot work as "me" always refers to the class instance in which you are present.
Now in this case what you need to do is :
1) create an attribute <view_controller> in your context class. Here the context is TRADE. The type of this attribute wud be same as the view controller class CL_TPMOE_HEADEREOF0_IMPL
2) Go to the view controller class and redefine the method
DO_VIEW_INIT_ON_ACTIVATION. This method is called only once when the view is loaded for the first time.
3) In this method, put the following code
me->typed_context->(Trade)->[view_controller] = me.
by the above code, you are setting the newly created attribute to the view controller instance.
4) The next step would be, go back to your getter setter methods or what ever it may be, try referring to the Fund plan ID by the code snippet mentioned below
data: lr_entity type ref to cl_crm_bol_entity.
lr_entity ?= me->[view_controller]->typed_context->[the context node in which the fund plan id is present]->get_current().
lv_field_value = lr_entity->get_property_as_String( **pass the field name here ).
This should definitely resolve the problem.
Thanks,

How can I bind a dynamic attribute of a context node to ALV?

Hi all,
I'm trying to show data with Webdynpor ALV, but i met a question which blocked me. The situation is that there is a static context node and it's mapped to WD ALV, while programming I create a dynamic attribute to the context node. The dynamic column can be shown on the UI, but there is no any data in it. How can i deal with it?
Thanks a lot!

How to use attributes from different context nodes in one view?

I am VERY new to the concept of CRM and currently working on creating an alternate version of the BP_HEAD_SEARCH. With help from SAPPRESSs book 'SAP CRM Web Client' i was ble to create my own simple Z-component.
However after going back and forth the book and the forum (including this [article|https://wiki.sdn.sap.com/wiki/display/CRM/Howtoaddanexistingfieldtoasearchpageofadifferent+component]) i was not able to find a solution to my problem. My current search uses BuilHeaderAdvancedSearch as context node for searching. But the search should also be able to use attributes from BuilActivity, which is directly related to BuilHeader. I can't seem to find a way to get attributes from BuilActivity into the search window of my component without having to change SAP-Standard.
Is this really the only way? Please advise on possible code and insertion point.

Any suggestions?

Adding dynamic attributes to static context node

Hi All,
I have defined a context node LINES with several attributes. This is done staticly during developmenttime.
During run-time node LINES is extended with several attributes dynamicly. See below:
10 HEADER_GUID ->
11 DETAIL_GUID ->
12 EXTERNAL_ID ->
13 OBJECT_TYPE ->
14 IN_OUT_PLAN ->
15 TRAFFIC_LIGHT_1 ->
16 TRAFFIC_LIGHT_2 ->
17 TRAFFIC_LIGHT_3 ->
18 TRAFFIC_LIGHT_4 ->
19 _LOCATION \TYPE=STRING ->
20 _ZZTOPGROUPING \TYPE=STRING ->
21 _STATUS \TYPE=STRING ->
22 _100000200 \TYPE=STRING ->
19..22 are added dynamicly.
I have an internal table that matches de new context. This <fs_tb_tree_new> I want to bind like:
*&- bind table
lr_node->bind_table( new_items = <fs_tb_tree_new>
 set_initial_elements = abap_true ).
In <fs_tb_tree_new> the dynamicly added attrbutes contains values e.g. (the static attributes also have values via <fs_tb_tree_new>):
 _LOCATION _ZZTOPGROUPING _STATUS _100000200
5 Africa 0002 Reporting Entity 0.000
6 Russia, CIS 0003 Identify 0.000
An ALV presents the values of the attribute. But.... only the values of the static part are presented, not the dynamic attributes added during runtime.
Please advise what I forget or do wrong .
Thanks in advance.
John

I solved the issue:
If you use a combination of static attributes added with dynanic attributes (during runtime) for dynamic ALV, I advise to create a new node and bind the values to this new created node:

Cannot read attribute of another context node in a context node

Hello Sap gurus,
such a long time that I do not post any issue. Now unfortunately time has come down.
My functional requirement is that whenever the status of an opportunity is changed from "Won" to "Booked", then I have to retrieve the Status reason previously marked for the status "Won" and paste into the attribute Status_Reason (CON_KEY) for status "Won".
In order to do that I need to read the context node BTADMINH or ZBTCUSTOMERH from the context node BTSUBJECT, in the method GET of attribute CON_KEY.
I have implemented the following code in the method GET_CONC_KEY of the context node BTSUBJECT.
DATA:
          lr_entity TYPE REF TO cl_crm_bol_entity,
        lr_comp TYPE REF TO ZL_BT111H_O_DETAILS_IMPL,
         lv_ref_guid     TYPE        crmt_object_guid,
         lr_collection TYPE REF TO cl_crm_bol_bo_col,
         lr_bdc type ref to if_crm_ui_data_context.
    TRY.
lr_entity ?= lr_comp->ZTYPED_CONTEXT->ZBTCUSTOMERH->collection_wrapper->get_current( ).
     lv_ref_guid = lr_entity->get_property_as_string( iv_attr_name = 'REF_GUID' ).
      CATCH cx_sy_ref_is_initial.
      ENDTRY.
Whenever I try to read the context node BTADMINH or ZBTCUSTOMERH from BTSUBJECT I got always the same dump:
OBJECTS_OBJREF_NOT_ASSIGNED ZL_BT111H_O_DETAILS_CN06======CP CRM
Somethins is defitenely wrong and I am at the moment stuck with this code.
Please any help is really welcome.
Thanks in advance,
Andrea

Hi Andrea,
Sorry I got it wrong , for lr_comp you will have to take reference from controller IMPL class.
DATA:
          lr_entity TYPE REF TO cl_crm_bol_entity,
        lr_comp TYPE REF TO ( component controller IMPL class),
         lv_ref_guid     TYPE        crmt_object_guid,
         lr_collection TYPE REF TO cl_crm_bol_bo_col,
         lr_bdc type ref to if_crm_ui_data_context,
         comp_controller type cl_bsp_wd_component_controller.
lr_comp ?= me->comp_controller.
IF lr_comp IS BOUND.
    TRY.
lr_entity ?= lr_comp->ZTYPED_CONTEXT->ZBTCUSTOMERH->collection_wrapper->get_current( ).
     lv_ref_guid = lr_entity->get_property_as_string( iv_attr_name = 'REF_GUID' ).

How to access a dynamic created attribute in a context node?

Hello,
who could help? I can't set a value for a dynamically created attribute which is bind to a table.
My context of the view looks as follow (is defined in NetWeaver):
- Context
 - Availability (Node)
 - vctxService (Attribute)
 - vctxServiceDesc (Attribute)
 - ... (further predefined attributes)
 - ... (some have to be set dynamically as follows)
Then I have added attributes dynamically in the wdDoModifyView(...) - method, as follows:
for (int i = 0; i < max; i++) {
 // some code to dynamically create table columns
 // adding attributes dynamically
 IWDAttributeInfo attrInfo = wdContext.nodeAvailability().getNodeInfo(). addAttribute("vctxAvailability_" + i, "ddic:com.sap.dictionary.string");
 tv.bindText(attrInfo); // bind to TextView in table
In the method onPlugFrom... I tried to set the values for the attributes "vctxAvailability_ + i" as follows:
for (int i = 0; i < max; i++) {
 IAvailabilityElement newAvailNodeElement = wdContext.createAvailabilityElement();
 // some values will be set for the
 // predefined attributes of AvailabilityNode
 // newAvailNodeElement.set...( value );
 // newAvailNodeElement.setVctxService( xy.getServ() );
 // now the values of dynamically created and added
 // attributes in AvailabilityNode will be added
 // THIS DOESN'T WORK
 newAvailNodeElement.setAttributeValue ("vctxAvailability_" + i, "value" + i);
It would be great if someone could help me.
Thanks in advance.
Kind regards,
Carsten

Carsten,
Here is a sample code that creates context attributes dynamically and also sets values:
//Creates a node
IWDNodeInfo nodeInfo = wdContext.wdGetAPI().getRootNodeInfo().addChild("TestNode", null, true, true, false, true, false, true, null, null, null);
//If you want to bind the node to a model node then the
//second argument to the above method should be the
//model class.
//Creates an attribute under the node just created.
IWDAttributeInfo testAttrib = wdContext.wdGetAPI().getRootNodeInfo().getChild("TestNode").addAttribute("testAttrib", "ddic:com.sap.dictionary.string");
IWDNodeElement testNode = wdContext.getChildNode("TestNode", IWDNode.LEAD_SELECTION).getCurrentElement();
IWDNode testNode2 = wdContext.getChildNode("TestNode", IWDNode.LEAD_SELECTION);
//Now you can bind testNode with the Model Node
//You can also set a value to the newly created attribute
testNode.setAttributeValue("testAttrib", new String("Value"));
Hope this helps.

Access to an attribute of a value node of a component controller

Hello experts,
I'm new to the area of SAP CRM Web Client UI development. My problem is probably very simple and you will surely smile about it.
I have created my own component with the value node FILE (that consists of five atributes) in the component controller. Unfortunately I have not figured out yet how I can access the value of an attribute.
The first thing I do not know is where I can find the controller-ID.
In addition, I get an syntax error Field "TYPED_CONTEXT->FILE->COLLECTION_WRAPPER->GET_FIRST(" unknown in the line with "lo_entity = me->comp_controller->typed_context->file->collection_wrapper->get_first( ).".
Currently no functionality is included in my code, because firstly I want to understand the basics.
method OP_FILEUPLOAD.
data lo_entity type ref to if_bol_bo_property_access.
data lv_file_name type string.
data lr_file_content type ref to data.
field-symbols <lv_file_name> type string.
IF ( comp_controller is INITIAL ).
 get_controller( 'xxxx' ).
ENDIF.
lo_entity = me->comp_controller->typed_context->file->collection_wrapper->get_first( ).
while lo_entity is bound.
 lv_file_name = lo_entity->get_property_as_string( 'FILE_NAME' ).
 lr_file_content = lo_entity->get_property( 'FILE_CONTENT_STRING' ).
 assign lr_file_content->* to <lv_file_content>.
 lo_entity = me->typed_context->file->collection_wrapper->get_next( ).
endwhile.
endmethod.
I hope that I will manage my "problem" with your help!

Hi Sebastian,
The issue is in the following line of your code:
lo_entity = me->comp_controller->typed_context->file->collection_wrapper->get_first( ).
The 'typed_context' belongs to your own component controller class and not the standard framework superclass. So, you need to replace this single line of code with something as follows (assuming that your component controller class is ZCL_CUSTOM_BSPWDCOMPONENT_IMPL):
DATA lr_coco TYPE REF TO ZCL_CUSTOM_BSPWDCOMPONENT_IMPL.
lr_coco ?= me->comp_controller.
lo_entity = lr_coco->typed_context->file->collection_wrapper->get_first( ).
The me->comp_controller reference will refer to the standard framework superclass of all component controllers and this does not have any typed_context attribute with it. The real component controller that gets created when you create a BSP component will have this attribute. That is why you need to first cast it to your own reference type before trying to access its typed_context.
And if your value node will have only single values, then you can as well do the following to access the attribute ATTRIB1 of context node node1:
DATA lv_value TYPE string.
lv_value = lr_coco->typed_context->node1->get_attrib1( attribute path = '' ).
Basically all attributes can be accessed by above code by using the right getter method.

ICWC: table shows all attributes of context nodes instead of the configured

Hi,
after adding an attribute by the assistant (from a BOL-relation of the root object) and setting it to the configuration, the table shows ALL attributes (~20) of the context node. With F2 in the browser I can see, that the right configuration was found (with 5 attributes). Clicking the customizing icon of the table, the popup is showing the configured attributes. Doing a "Set to default" has no result.
Removing the added attribute: no change.
Removing all attributes: no change
Deleting the configuration and create a new one with the same name: no change
Please help!!!
Thanks,
TW

Hi everyone,
the previously described problem could be solved by removing the enhancement of the View and creating a new configuration. The creation of only a new configuration has not solved the problem. However, removing a view enhancement can not be the solution for such a problem!
Now again we have the problem after adding an attribute at the context node used for the table, the configuration seems to be damaged and the filtering of the attributes does not work. Thus, all available attributes are used. Debugging in the htm-tag has shown that the XML for the configuration is correct and read in the view. Further debugging has not shown any exceptions or any hints on the weird behavior.
Had anyone of you the same or a similar experience and solved this in another way than removing the enhancement of the view?
With best regards,
Kai Lienemann

How to find if a particular context node attribute is changed.

Hi,
When a screen is opened, the context node attribs has some values. On some event, i wanted to check if one particular attribute in the context node has changed. Is it possible to figure this out.
(ps note that I need not find if any change has happened to the entire table but only one column (attribute) of the node. Note that the node has cardinality 0...n. So there are multiple possible values)
Thanks in advance.
regards,
suresh.

Hi,
If you use the [Context change log|http://help.sap.com/saphelp_nw2004s/helpdata/en/ae/f95e42ff93c153e10000000a1550b0/frameset.htm]
and loop over the result table, looking for a certain attribute name and node name,
you'll get all the changes of that attribute, for all elements in that node.
