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
Shivi

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 .
DATA lr_root_container TYPE REF TO cl_wd_uielement_container.

    lr_root_container ?= view->get_element( 'ROOTUIELEMENTCONTAINER' ).
    lr_tabstrip ?= lr_root_container->get_child( id = 'TABSTRIP1' ).        "GETTING THE TABSTRIP
    lr_tab      ?= lr_tabstrip->get_tab( id = 'TAB1' ).        "GETTING THE TAB INSIDE TABSTRIP
    lr_table    ?= lr_tab->GET_CONTENT( ).      "GETTING THE CONTENT(TABLE IN THIS CASE) INSIDE TABSTRIP
    lr_table_column ?= lr_table->get_grouped_column( id = 'TABLE_MAIN_PERNR' ).   "GETTING THE COLUMN INSIDE THE TABLE
    "Table popin
    lr_table_popin ?= lr_table_column->GET_POPIN( ).   "GETTING THE POPIN INSIDE THE TABLE
    lr_tc ?= lr_table_popin->GET_CONTENT( ).   "GETTING THE CONTENT(TRANSPARENT CONTAINER IN THIS CASE)INSIDE THE TABLE
    lr_table2 ?= lr_tc->get_child( id = 'TABLE_EMPLOYEE' ).        "GETTING THE EMPLOYEE TABLE INSIDE THE TRANSPARENT CONTAINER
    lr_table2_column ?= lr_table2->get_grouped_column( id = 'TABLE_EMPLOYEE_PERNR' ).   "GETTING THE COLUMN INSIDE THE TABLE
    lr_table2_column->SET_VISIBLE( '02' ). "SETTING VISIBILITY FOR THE COLUMN
ENDIF.
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.
Thanks,
Saikat

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!

Office UI element in Web Dynpro ABAP

Hi ,
I am using Office UI element to display a excel on WDA screen . The excel has some macros .
I need to send some data of excel to the DB on click of Save .
How do i read the excel data ? The data is in the format of XSTRING .
I tried to convert to STring and then Table . But its giving me dump .
Can anyone Suggest how can i do this ?

Hi anuradha ,
I think it is not possible to convert xls file's xtring to a propert string format.
only .csv fromat file will give you the proper string when converted from xstring to string.

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?

Adobe form to save data using Web Dynpro ABAP

Hi. I am pretty new to SAP world and trying to learn and work on a task given to me relate to
creating Adobe offline form using Web Dynpro ABAP same time.
I have several questions and hopefully, many gurus like you will provide answers.
I noticed there are many examples creating and using Adobe interactive forms (though not many newer version),
but I didn't see (at least I didn't find any) any detail example on saving data to an internal table (such as fixed assets, vendor master, etc)
using interactive form. Is there any detail explanation/example on this?
I have ask this question in another forum (before I found this forum) but didnu2019t get the answer yet.
2. When I tried to see graphic layout and modify the layout from Web Dynpro, I can't see the graphic layout.
All I see is text list of fields/buttons that I created, but can't see section for graphic layout where I can modify layout.
I am sure I didn't install/configure something correctly.
Anyone has any idea what I didn't do?
I have another question, but I will wait till later after I figure out above ones first.
Thanks for all your help in advance.
John

Hi John,
In the WD4A view, there is a button "Show/Hide Layout Preview".
Click on that button to be able to see the Layout.
Note that this button is next to the Pretty Print button.

Reema.

Interactive Form within Web Dynpro ABAP

Hi,
I've an Adobe interactive form element within Web Dynpro ABAP view. I've more than one WebDynproActiveX buttons within the Interactive form (like Submit, Cancel, Clear).
How can I differentiate the user selection within Webdynpro ? Whether the user selected Submit or Cancel or Clear ? Can we associate any function code for each button ?
Thanks
Ravikumar

Hi Ravi,
You can take a context attribute lets say "STATUS"(string) in your form context. For your buttons in the form, in click event set the value. like
STATUS.rawValue = "1"; (eg Submit)
STATUS.rawValue = "2"; (eg Cancel)
And in your submit event read this context attribute and you can use CASE like when 1 , when 2 etc and you can execute your code accordingly.
it should solve your problem.
With Regards,
Ravi.D
