Dynamic Context Mapping in Web Dynpro ABAP

Hi Experts,
How can I create two dynamic Context nodes, one in ViewController and the other in Component Controller and finally create a context mapping between them?
Regards,
Johan Kriek.

Hi Johan,
I found a method IF_WD_CONTEXT_NODE_INFO~ADD_NEW_MAPPED_CHILD_NODE that seems to be the one that I am looking for.
I do have same idea but i have been trying to give solution by using above method,unfortunately here my server is down.check the below code. i didnt check this code due to server down.
DATA: lo_nd_purchase_header TYPE REF TO if_wd_context_node,
      lo_el_purchase_header TYPE REF TO if_wd_context_element,
ls_purchase_header TYPE wd_this->element_purchase_header,

      lo_child_node_info type ref to if_wd_context_node_info,
      MAPPING_INFO type WDR_CONTEXT_MAPPING_INFO.
* navigate from <CONTEXT> to <PURCHASE_HEADER> via lead selection
lo_nd_purchase_header = wd_context->get_child_node( name = wd_this->wdctx_purchase_header ).
              CALL METHOD LO_ND_PURCHSE_HEADER->GET_NODE_INFO
                RECEIVING
                  NODE_INFO = lo_node_info.

Cannot see Ecatt option in context menu in web dynpro abap in SE80 ECC 6.0

Hi ,
I saw a presentation by Thomas in which there is option of recording ecatt script on context menu in web dynpro abap application.we are on ECC 6.0 we are trying to record WDA applications and test them by using Ecatt but I am unable to see the option of recording the ecatt script in SE80 editor.
Why could this be happening

Thanks ,
I saw that disappointing note ...any other way to automate web dynpro abap testing ? please advise.

Dynamic table columns in web dynpro abap

Hi,
In my current project I have got a requirement whose solution I am not able to figure out.
My requirement is this:
I will have a table containig budget owners name(since its compensation management in HR).There will be a table popin inside this table on the click of the personal number of the budget owner. Now the table popin will have another table with all employees name under that particular budget owner.
The problem is that the table inside the popin will not be having fixed columns.Actually the columns will be coming from a standard java web dynpro application (say in the form of an internal table).
My requirement is this how can this be handled?Can we include all the possible columns in the node(which i bind to the child table) and make them visible/invisible during runtime? or create a dynamic node and assign it to the table(but in this case a node needs to be bound to the table during design time,what to bind?) ?
Can u please help along with code snippets.
Thanks and Regards,
Saikat.

Thnx for the input.
I am abke to make the table columns inside the popin visible/invisible.
I have a tabstrip.Indise one of the tabs is my main table and inside one of the columns is the popin.Inside that a transparent container and finally the table inside that.
This is the code that worked for me.
METHOD wddomodifyview .

    lr_table2_column->SET_VISIBLE( '02' ). "SETTING VISIBILITY FOR THE COLUMN

ENDMETHOD.
But I'm still considering the dynamic node concept.Lets see if this works out or not.If not then I'll have to go for the dynamic node thing.

Dynamic context binding in web dynpro alv

I use dynamic context binding (see code below to show and edit the ALV table.
'DB_TABLE' is a tranparent table. It works fine.
But now this table should be expanded with additional fields which are only known at runtime and could be different from case to case.
How can I get these fields in the context dynamically?
DATA:
        rootnode_info TYPE REF TO if_wd_context_node_info,
        dyn_node      TYPE REF TO if_wd_context_node,
        tablename   TYPE string.
rootnode_info = wd_context->get_node_info( ).
tablename = 'DB_TABLE'.
cl_wd_dynamic_tool=>create_nodeinfo_from_struct(
    parent_info = rootnode_info
    node_name = tablename
    structure_name = tablename
    is_multiple = abap_true ).
DATA:
        stru_tab TYPE REF TO data.
FIELD-SYMBOLS: <tab> TYPE table.
CREATE DATA stru_tab TYPE TABLE OF (tablename).
ASSIGN stru_tab->* TO <tab>.
SELECT * FROM (tablename) INTO CORRESPONDING FIELDS OF TABLE <tab>.
dyn_node = wd_context->get_child_node( name = tablename ).
dyn_node->bind_table( <tab> ).

You should create a structure dynamically and use this as the context structure. See the coding below, where a structure is created, which contains CARRID and CONNID.
DATA: node_info type ref to if_wd_context_node_info,
      struct_type TYPE REF TO cl_abap_structdescr,
      table_type type ref to cl_abap_tabledescr,
      comp_tab    TYPE cl_abap_structdescr=>component_table,
      comp        LIKE LINE OF comp_tab,
      my_table    type ref to data,
      my_row      type ref to data.
field-symbols: <table> type table,
                 <row> type data,
                 <flight> type sflight.
* build a structure description from the list of single fields
comp-name = 'CARRID'.
comp-type ?= cl_abap_datadescr=>describe_by_name( 'S_CARR_ID' ).
APPEND comp TO comp_tab.
comp-name = 'CONNID'.
comp-type ?= cl_abap_datadescr=>describe_by_name( 'S_CONN_ID' ).
APPEND comp TO comp_tab.
* note this structure contains the fields "CONNID" and "CARRID"
struct_type = cl_abap_structdescr=>create( comp_tab ).
* now the nodeinfo is created
node_info = wd_context->get_node_info( ).
node_info = node_info->add_new_child_node(
    name                         = 'MY_NODE'
    IS_MANDATORY                 = ABAP_true
    IS_MULTIPLE                  = ABAP_true
    STATIC_ELEMENT_RTTI          = struct_type
    IS_STATIC                    = ABAP_false
* fill new node;
data: l_node type ref to if_wd_context_node,
        l_flight type STANDARD TABLE OF sflight.
l_node = wd_context->get_child_node( 'MY_NODE' ).
l_flight = wd_assist->get_flights( ).
* if you could create a local data type, would be fine, but if you have to do it dynamically ...
struct_type = node_info->GET_STATIC_ATTRIBUTES_TYPE( ).
* create tabledescriptor from structdescription (standard table, no keys)
table_type = cl_abap_tabledescr=>create( p_line_type = struct_type ).
create data my_table type handle table_type.
assign my_table->* to <table>.
loop at l_flight assigning <flight>.
    create data my_row type handle struct_type.
    assign my_row->* to <row>.
    move-corresponding <flight> to <row>.
    append <row> to <table>.
endloop.
l_node->bind_table( <table> ).

Context Mapping in web dynpro

Hi,
Steps which I underwent for context mapping is:
1. Opened view designer for start view .
2. Choose the context tab.
3. Opened the context menu for the root node context n choosed the option New->Value attribute.
4. entered the name for the attribute such as name n choosed finish.
5. From the context menu for the attribute Name choose Edit Context Mapping.
Problem is in my case "edit context mapping" is disable.

Hi
u have to add the Component Controller In the required Controllers List of the view
thwn u fill find the it enabled.
Suppose u want to map the value Attribute in the view to that of the Attribte in the Component Controller then add that ComponentContolle Name in the required Controllers of the view
ur Component controler shuld also have the Value Attribute of same data type.
u can go properties of the View there u have required Controllers and Add Button click on that and add ur controller Name

Creating Dynamic UI Elements in Web Dynpro ABAP

Hi,
I want to an application in which the context nodes and the UI Elements for the second screen get created dynamically at run time based on the input on the first screen
First i have used this method :
cl_wd_dynamic_tool=>create_nodeinfo_from_struct()
to create the dynamic context nodes.
I have checked in debugger and the dynamic context node is getting creates successfully.
I have saved the reference for the context node in DYN_NODE.
Now for creating the dynamic UI Elements corresponding to the attributes of this context node, i call the method :
cl_wd_dynamic_tool=>create_form_from_node(
ui_parent = group_1
node = dyn_node
inputlength = 20 ).
But this thing is dumping.
This is the dump.
The following error text was processed in the system CG7 : Adapter error in &VIEW_ELEMENT_TYPE& "BP_ICLIENT" of view "ZWD_ONLINE_FORMS.FINAL_VIEW": Context binding of property VALUE cannot be resolved: Node FINAL_VIEW.1.BP does not contain any elements
Where BP_ICLIENT is the first attribute of the dynmaic context node BP created..
Please Help.
Thanks

Dynamic ALV columns in Web Dynpro ABAP

Hello masters:
Does anybody know how to build an ALV with dynamic columns in a WD4A?
I know how to make an ALV with a dynamic context node (dynamic DDIC structure), but it isn't the problem. First, I need to validate data entries, and then I will know how many fields I have to show.
I've been reading about interface IF_WD_CONTEXT_NODE_INFO. I think some of its methods can be useful to me. Can you help me to solve that?
Thanks.

Hi Rodrigo,
There are two ways for it:
1) Creating an attribute dynamically under the Staticly defined node.
2) Creating a new node dynamically with your desired columns in it.
I am explaining the second process, Here it as follows:
1. Create a WDC, and use the component SALV_WD_TABLE.
2. Create a node in the context to store the defined strucutre name.
3. Read the node and set the structure name to that node from which you want to get the columns.
4. Use this structure name and create a new node dynamically.
5. Set the data to this dynamically created node.
6. Set this context node to ALV.
Here is the sample code:
To get the strcutre from where you want to fecth the fields.
tabname_node->get_attribute( Exporting name = 'TABLENAME'
                              Importing value = tablename ).
translate tablename to upper case.
*create sub node named TEST1 of structure (tablename)
cl_wd_dynamic_tool=>create_nodeinfo_from_struct(
   parent_info = rootnode_info
   node_name = tablename
   structure_name = tablename
   is_multiple = abap_true ).
DATA: stru_tab type ref to data.
field-symbols: <tab> type table.*Create Internal Table
create data stru_tab type table of (tablename).
assign stru_tab->* to <tab>.*Get table content
select * from (tablename) into corresponding fields of table <tab>.*get instance of new node
dyn_node = wd_context->get_child_node( name = tablename ).*Bind Internal table to context node.
dyn_node->bind_table( <tab> ).*instantiate alv component
data: l_ref_cmp_usage type ref to if_wd_component_usage.l_ref_cmp_usage =   wd_this->wd_cpuse_alv( ).
if l_ref_cmp_usage->has_active_component( ) is initial.
l_ref_cmp_usage->create_component( ).
endif.*pass context node to alv
data: l_ref_interfacecontroller type ref to iwci_salv_wd_table .
l_ref_interfacecontroller =   wd_this->wd_cpifc_alv( ).
l_ref_interfacecontroller->set_data( dyn_node ).
Hope it helps..
Good day!

Shashikanth. D

Portal dynamic iView from Web Dynpro ABAP?

I wish to use a "Dynamic iView" from a Web Dynpro ABAP application, but it appears the API is only available in Web Dynpro Java. Can this feature be used from Web Dynpro ABAP, or can this be accomplished in another way?
Scenario: I have two iViews on a page, one Web Dynpro ABAP and another iView whose source I want to change dynamically based on something a user clicks in the Web Dynpro ABAP.
Dynamic iView:
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/44/a72c155df77038e10000000a422035/frameset.htm

So you are suggesting the WDA fires an event to a new WDJ that we would need to create that would in turn use the Dynamic iView service mentioned in that help document?

Adding rows in web dynpro ABAP Dynamic Interactive form.

Hi Experts,
I am having problem in web dynpro ABAP Dynamic Interactive form.
This is my scenario....
I have a dynamic interactive form that has buttons to add and remove rows in a table. It works fine when I preview it , but when I render, view or save it using ADS, it no longer works. The "add" button actually does instantiate more repeating rows, because I put some trace messages in to count them, but the added rows are not displayed. How do I make them visible?
In web dynpro java we write some coding in modify view to set the pdf form as dynamic
IWDInteractiveForm iForm =
(IWDInteractiveForm)view.getElement("<ID>");
iForm.setDynamicPDF(true);
simillarly what we need to write in web dynpro ABAP.
Please give me solution for the same.
Thanks,

Reading Dynamic Table Values in interactive form (web Dynpro ABAP)

Hi All,
I have created a Web Dynpro ABAP application which contains an Interactive Form, That Adobe Interactive Form contains Dynamic table (New rows can be added manually and deleted using a button).
I am not able to read the Dynamic table values in Web Dynpro u201COn Submitu201D.
In the Adobe form I have web Dynpro native button (I am using ZCI), while clicking the native button I need to read the dynamic table values.
How can I resolve this problem.
Thanks and Regards,
Boopathi M

that means, when u add the table instance at runtime, you will also have to add an element to the node that is bound to the table.
probably addNew() mathos may be useful to you.
it appends a new record to the record set.
xfa.sourceSet.dataConnectionName.addNew()
also when on the exit event of the table field, do the following:
var i = xfa.parent.index
$record.rootnodename.tablenodename.data<i>.fieldname = $.rawValue
xfa.host.messageBox($record.rootnodename.tablenodename.data<i>.fieldname)
