How to create a context element

Hai,
How can i create a context element for a view dynamically.
regards,

Hi,
Context element or context attribute?
For context element use appropriate method in your IWDNode implementation and after creation call add method of node.
For context attribute - see appropriate tutorial : https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/webdynpro/tutorial on dynamic programming of web dynpro applications - 17.htm

How to create dynamic context based on a structure defined in the program?

Hi Experts,
         I need to create a dynamic context based on a structure wa_struc which i have define programatically.
When I pass wa_struc to structure_name parameter of create_nodeinfo_from_struc, i get a runtime error:
"Parameter STRUCTURE_NAME contains an invalid value wa_struc."
How to create dynamic context based on a structure defined in the program?
I have written the code like this:
TYPES: BEGIN OF t_type,
            v_carrid TYPE sflight-carrid,
            v_connid TYPE sflight-connid,
         END OF t_type.
Data: i_struc type table of t_type,
         wa_struc type t_type.
data: dyn_node   type ref to if_wd_context_node.
data: rootnode_info   type ref to if_wd_context_node_info.
rootnode_info = wd_context->get_node_info( ).
clear i_struc. refresh i_struc.
select carrid connid into corresponding fields of table i_struc from sflight where carrid = 'AA'.
cl_wd_dynamic_tool=>create_nodeinfo_from_struct(
parent_info = rootnode_info
node_name = 'dynflight'
structure_name = 'wa_struc'
is_multiple = abap_true ).
dyn_node = wd_context->get_child_node( name = 'dynflight' ).
dyn_node->bind_table( i_struc ).

Hi Michelle,
          First of all Special thanks for your informative answers to my other forum questions. I really appreciate your help.
Coming back to this question I am still waiting for an answer. Please help. Note that my structure is not in a dictionary.
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
I have updated my code like the following and I am getting error:
TYPES: BEGIN OF t_type,
CARRID TYPE sflight-carrid,
CONNID TYPE sflight-connid,
END OF t_type.
Data: i_struc type table of t_type,
dyn_node type ref to if_wd_context_node,
rootnode_info type ref to if_wd_context_node_info,
i_node_att type wdr_context_attr_info_map,
wa_node_att type line of wdr_context_attr_info_map.
wa_node_att-name = 'CARRID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CARRID'.
insert wa_node_att into table i_node_att.
wa_node_att-name = 'CONNID'.
wa_node_att-TYPE_NAME = 'SFLIGHT-CONNID'.
insert wa_node_att into table i_node_att.
clear i_struc. refresh i_struc.
select carrid connid into corresponding fields of table i_struc from sflight where carrid = 'AA'.
rootnode_info = wd_context->get_node_info( ).
rootnode_info->add_new_child_node( name = 'DYNFLIGHT'
attributes = i_node_att
is_multiple = abap_true ).
dyn_node = wd_context->get_child_node( 'DYNFLIGHT' ).
dyn_node->bind_table( i_struc ).
l_ref_interfacecontroller->set_data( dyn_node ).
But now I am getting the following error :
The following error text was processed in the system PET : Line types of an internal table and a work area not compatible.
The error occurred on the application server FMSAP995_PET_02 and in the work process 0 .

How to create an UI element dynamically on action in drop down?

Hi,
How to create an UI element dynamically on action of selecting a value from the drop down?
help out with the steps i need to follow..

Hi,
Dynamic UI Element creation
We can create it only in the WD Modify View.
Get the instance for the Root UI Element Container.
Create the UI element Ex: Input Field, Text View etc.
Bind the UI Element to the Attribute Value.
Now bind the UI Element to the Root UI Element Container.
 IWDTransparentContainer root =(IWDTransparentContainer)view.getRootElement();
 IWDDropdownByIndex DdbName = (IWDDropdownByIndex)view.createElement(IWDDropdownByIndex.class,"DdbName");
 IWDDropdownByIndex DdbAge = (IWDDropdownByIndex)view.createElement(IWDDropdownByIndex.class,"DdbAge");
 IWDDropdownByIndex DdbGender = (IWDDropdownByIndex)view.createElement(IWDDropdownByIndex.class,"DdbGender");
 IWDNode Mad =wdContext.getChildNode("Person",0);
 IWDAttributeInfo NameAtt = Mad.getNodeInfo().getAttribute("Name");
 IWDAttributeInfo AgeAtt = Mad.getNodeInfo().getAttribute("Age");
 IWDAttributeInfo GenderAtt = Mad.getNodeInfo().getAttribute("Gender");
 DdbName.bindValue(NameAtt);
 DdbAge.bindValue(AgeAtt);
 DdbGender.bindValue(GenderAtt);
 root.addChild(DdbName);
 root.addChild(DdbAge);
 root.addChild(DdbGender);
Dynamic Action Creation
Create the Action in the Action tab.
Create a Button.
Get the reference for the created action (Through the Event Handler).
Bind the Action to the Button.
Bind the Button to the Root UI element Container.
IWDButton ButGo = (IWDButton)view.createElement(IWDButton.class,"ButGo");
IWDAction ActGo = wdThis.wdCreateAction(IPrivateStartView.WDActionEventHandler.GO,"Click");
ButGo.setOnAction(ActGo);
root.addChild(ButGo);
Now write the required code for the Event Handler that is associated with the Action.
//@@begin onActionGo(ServerEvent)
 IWDNode Mad = wdContext.getChildNode("Person",0);
 wdComponentAPI.getMessageManager().reportSuccess(Mad.getCurrentElement().getAttributeAsText("Name"));
 wdComponentAPI.getMessageManager().reportSuccess(Mad.getCurrentElement().getAttributeAsText("Age"));
 wdComponentAPI.getMessageManager().reportSuccess(Mad.getCurrentElement().getAttributeAsText("Gender"));
//@@end

How to create a container element?

Hi,
Could somebody please tell me how to create a container element and how to create a multi container element? How is this element used in the fork step?
I am using a fork with 3 branches but the agent assignment is a problem.The workitem does not go to the user set in the agents tab.
Regards,
Monica.

Hi Monica,
Within your Workflow Builder, there is a box on the left hand side that (Workflow Container). You should have an option (in change mode) to right-click and create or double-click on the <Double-Click to create> tab.
Or you can go to the Workflow Container "Goto -> Workflow Container" and click on the "Create" <F5> icon.
Same theory applies to creating a container element in your task. Go to your task and click on the "Container" button and select "Create".
When creating your container, you can specify if it is a multiline container by checking "Multiline" under the container attributes.
In a fork step, you would really only use your "Container Element" in the "End Condition" of a Fork step.
Please advise what the "Agent Assignment" is referring to when you're using it in your fork? Which step in the fork?
If you are assigning agents in one step of the fork, you cannot expect these agents to apply to your other 2 fork steps. The forks work independently of each other (to a point).
Please provide more information if you need more help.
Kind regards,
Tom

Code to create dynamic context elements

Dear Guys,
I have create a dynamic text edit using the following code in abap webdynpro.
I have created a transparent container named PREREPLY set to grid layout and created a context REPLY type string and in WDDOMODIFYVIEW view i have written the following
data : lr_container type ref to cl_wd_uielement_container,
         lr_comment type ref to cl_wd_text_edit.
lr_container ?= view->get_element( 'PREREPLY' ).
lr_comment = cl_wd_text_edit=>NEW_TEXT_EDIT( BIND_VALUE = 'REPLY'
                                                                                COLS = 70
                                                                                ID = 'PREREPLIES2'

lr_comment->BIND_VALUE( 'REPLY' ).
cl_wd_grid_data=>new_grid_data( element = lr_comment ).
lr_container->ADD_CHILD( lr_comment ).
i am able to see a new textedit when i run my application.
Now I want to create the context also dynamically, because i will not know how many text edit will be there. Based on the number of lines in the internal table i want the create the context and textedits dynamically.
Give me the code to create context dynamically in abap webdynpro.

How to create a context menu in ALV table cell editor(Webdynpro abap )

Hello Experts,
I am having a problem in creating a context menu in a table cell editor in the ALV table output.I have assigned a 'lta' as the cell editor.But befor assigning the lta as cell editor I have assigned the menu to the lta.But when the view is rendered I can see the lta with the actioned assigned to it.But I cannot see the context menu.
The code snippet below:
"Create menu for each coloumn
create OBJECT lo_menu_actions type CL_SALV_WD_VE_MENU EXPORTING
      id = 'MITM_ACTIONS'.
lo_menu_actions->set_visible( value = abap_true ).

    id = 'MITM_CREATE_EXPRESSION'.
lo_menu_item_create->set_visible( value = abap_true ).
lo_menu_item_create->set_visible_fieldname( value = 'Create' ).

    lr_column->set_cell_editor( lo_lta ).
    IF ls_node_dec_tab_cols-is_result EQ abap_true.
      lr_column->set_cell_design( value =
                  cl_wd_table_column=>e_cell_design-key_medium ).
    ENDIF.
ENDLOOP.

Hi Prakash,
I have not come across this requirement till now to have context menu in a cell editor of alv.
Unfortunately the implementation of method SET_MENU of alv ui elements ( ex: cl_salv_wd_uie_text_view ) is not updating alv configurable table, instead it just stores in a global attribute as string. Hence has no effect on context menu.
If your user is very particular about this requirement of having context menu in cell editor, you can go for a normal table. Because, normal table's cell editor has the property to set the menuID as we do it for other ui elements.

Rama

How to create a context node for "IBHeader" at the view "BuPaIBaseDetail"?

hi, experts
for the requirement, i have to get data from a root BO-IBHeader in the view of "BuPaIBaseDetail".But the view already has IBHeader's child object-"IBComponent", whose controller class is "CL_CRM_IC_BUPACONTROLLER_CN08", how can i create the context node for "IBHeader"?
angerly wait for the answer. thanks a lot

If you right click on an empty container or a container with an object in it, it has the same available choices to select. However, if you create a blank property node on the block diagram, and wire up the .net object to it, you will see a much different list of properties.
So, the property node created from right clicking a .NET container will be for that container, even if there is an object inside. To create a property node for the object, you must wire the .NET object to an empty property node on the block diagram.

How to create a container element in workflow container

Hi,
I am learning WF by a Tutorial. In which absence of notification was considered as example. As per tutorial, I created two task for creating a Notification and checking a absence
In the next step it ask to create a container element(approver) to workflow container. How i can create the same.
Also, please clarify me on the binding between task container and workflow container....with this example
Thanks
Suresh

Hi,
On the workflow builder LEFT side below the navigation area u can see this <Double-Click to Create>.
Double click and create the container.
During binding it looks as follows.
Workflow -
> Task
Workflow <----
Task
What happen here is from workflow the data passed to task and it is used for processing, after that it returned back to the workflow. Now u can create the container on bothside and bind the data. ie Variables.
Creating container u can refer : http://www.****************

How to create SOAP Header elements using SAAJ??

I am facing a problem when adding header elements under SOAP Header
using SAAJ(api).
I want to create a structure as following:
I get a empty SOAP header obejct by writing code--> SOAPHeader header
= envelope.getHeader();
But not able to add SOAP header elements as specified in example
below. I tried but its giving me error as
"HeaderElements must be namespace qualified"
CAN ANYBODY TELL ME THAT HOW TO ADD HEADER ELEMENTS USING SAAJ??
<SOAP:Header>
<AccountNumber>123</AccountNumber>
<AuthorisationCode>test111</AuthorisationCode>
<Source>abc</Source>
<Market>01</Market>
</SOAP:Header>

I'm including this comment from some code I've just written after wrestling with this for hours (I've actually left it on another post as well). The upshot of it all is that you have to include a namespace URI when creating a header in SAAJ:
 NOTE: SOAP 1.1 requires that all header entries be namespace-qualified to
 namespace URI's. The SAAJ 1.2 implementation requires a Name object with
 the namespace URI to make this happen even if the prefix used is already
 visible by being declared higher in the document (e.g. in the Envelope).
 However, the namespace URI is not present in the serialized header element
 as long as it was declared higher in the document. In order to create a
 header element without a prefix (to conform to a web service definition
 that doesn't use a prefix in its headers, for example), leave the prefix
 null in the addHeaderElement() method.
 For example, with a SOAPHeader 'hdr':
 //first create the name
 Name name = env.createName("my-local-name", null, "my-URI");
 //then create the header element
 SOAPHeaderElement he = hdr.addHeaderElement(name);
 This would result in an XML element that looked like this:
 <my-local-name xmlns="my-URI"/>
 This would allow SAAJ developers to create a header for a service that
 only expected a local name in its header elements (as many do!). As long
 as the service doesn't choke on the attribute (validation! evil!), this
 should work.

How to create a context menu which appears on right click

Hello Experts,
I want to create a context menu which should appear on the right click of a mouse anywhere on the screen.
I have seen this functionality in one of the sap applications, and i guess this is an inbuild functionality in Webdynpro for ABAP but in WebDynpro Java i haven't found any such inbuild functionality.
Does anybody have any idea about it ?

Context menus are not supported in NW04 and NW04s, they will be available in the next major release.
