Bind additional context elements

Hi
İs it necessary to restart AS Java when editing the model
binding and bind additional context elements to an
already existing Model Node in the context?

erdem

Hi,
It is only necessary when you are trying to reimport the BAPI ....incase your portal is IN SP14 then no problem.
You can use the ARFC tool to remove the cache
http://blrsapepdev002:50000/webdynpro/dispatcher/sap.com/tcwdtools/WebDynproConsole
Try removing the cache from here , or wht you can do ....open the JCO which is used for the MetaData and recreate it.
all of them works fine

How to bind a UI element to the context

Hi Experts,
 I have a problem binding UI element to the context. In my code i have to create TabStrips dynamically and under this tabstrip number of UI elements would be there. For this i have a code like this..
IWDTransparentContainer theActionContainer =(IWDTransparentContainer)view.getElement("RootUIElementContainer");
 IWDTabStrip ts = (IWDTabStrip) view.createElement(IWDTabStrip.class,"TabStrip");
 IWDTab tab1 = (IWDTab) view.createElement(IWDTab.class,"Tab1");
 IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
 IWDCaption header1 = (IWDCaption) view.createElement(IWDCaption.class,"Header1");
 header1.setText("Tab1");
 tab1.setContent(in);
 ts.addTab(tab1);
 IWDTab tab2 = (IWDTab) view.createElement(IWDTab.class,"Tab2");
 IWDInputField in2 = (IWDInputField) view.createElement(IWDInputField.class,"in2");
 IWDCaption header2 = (IWDCaption) view.createElement(IWDCaption.class,"Header2");
 header2.setText("Tab2");
 tab2.setHeader(header2);
 ts.addTab(tab2);
 theActionContainer.addChild(ts);
when i run this code it is giving following exceptions..
The initial exception that caused the request to fail, was:

From these exceptions what i understood is, i need to bind these UI elements to context.
 Can any body tell me how to bind a UI element to the context if I understood the exceptions correct..
Thanks in Advance,
Murthy.

HI,
lets say Ctx is your context attribute,
IWDAttributeInfo attrInfo = wdContext.getNodeInfo.getAttribute("Ctx");
then , as per your code,
IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
in.bindValue(attrInfo);
if your contex attribute is child of some other node then do like this,
IWDAttributeInfo attrInfo = wdContext.getNodeInfo.getChildNode("SalesOrder",0)getAttribute("Ctx");
//this is when Ctx is child of node SalesOrder, and we are taking Ctx from its 0th element
then ,
IWDInputField in = (IWDInputField) view.createElement(IWDInputField.class,"in");
in.bindValue(attrInfo);
include this in your code ,
let me know if you face any problem

Is it mandatory to bind each & every CONTEXT element to a text field on the form?

Hello,
I am developing an Adobe Interactive Form, i have Designer 8.1 and Reader 9.0 in my Windows 7 Laptop. When i checked the menu EDIT-->form properties --> Compatability, its Adobe XML form File (XDP)
I have 3 elements (say, 1_Name, 2_Street and 3_City) in the CONTEXT and drawn ONLY 2 input enabled TEXT fields (for items - Name and Street of conetext) and then, BINDED them.
I did not put any associate text field for CITY and no chance of binding!
Pls. let me know that, Now can i utilize this CITY (of context) element containign data in the Java script? is this CITY is VISIBLE in the java script, even though it did not get BINDED with any text field on the form?
THank you

Thank you.
If it got BINDED, i knew how to point/get/visible the CITY element (of CONTEXT) containming data by using the below java script,
(this.rawValue == "A") or i can also get it with script of VISITOR.Page3.Subform11.CITY.rawvalue = "A"
If i do NOT bind CITY to any TEXT FIELD of FORM, then, how i can retrieve/get/visible/point CITY content?

GeneralException Node(( Context path of node ): cannot bind or add element,

Hello all,
Stack trace :
GeneralException Node((<Context path of node>): cannot bind or add element, because it is already bound to a node
I am trying to upload data from excel file in web dynpro context.In the process, when I create and add an element to the node which I want to populate with excel data, it throws the above mentioned exception.
Any idea as to wht is causing the problem ?

Hi,
GeneralException Node((<Context path of node>): cannot bind or add element, because it is already bound to a node
It seems that its a mapped node, try to bind or addelements at the source.
Ex: If this node is mapped from controller to view try to add elements in contoller instead of doing in view.

How to bind Context elements to a HTML template

Hi,
I want to display all the context elements in my webDynpro application in a html page, I have html template my requirement is to bind all the context elements to fields in the html template.please provide me the solution.
thanks,
kishore.

Hi Kishor,
I do not think there is some straight forward solution for this scenario.
You need to create two applications 1 webdynpro application and one portal application.
What you can do is Pass the context values from webdynpro application to a flat file and store then in that(every time create a new flat file). Now after successfully creation of flat file call the portal application which reads the flat file and get the context values and set them.
If you require more info, i can help you.

OK that doesn't sound like that sould be the offical solution. I would suggest you open a support ticket and/or search for an existing note. Surely this is not normal functionality.

I have CONTEXT and drwan input text fields in my_interactive_form.
1) I want to debug the form that How the CONTEXT is holding the values and With wht values the HIDDEN input text fields are holding?
2) is it mandatory to BIND each & every CONTEXT element to a text input field on the form IN ORDER TO utilize the context element content in the Java script editor?

PROPERTIES, then i saw the "PDF Version: 1.6 (Acrobat 7.x)"
When i opened this VISITOR interactive form in the browser, i did not see MENU options (like EDIT)! i saw small icons of Pring, Save, Page, Zoom, Find.
And a Purple ribbon with text of "Please fill out the following form. You can save data typed into this form"

ContextException : cannot bind or add element

Hi all,
I can't find an answer to my problem.
Hope you'll be able to
Here are the facts :
Context :
I'm currently creating a TeamViewer for Managers to be able to select the employees they manage.
For that, I have a table which lists them all, displaying their infos in specific columns.
Both columns and data are dynamic and are specified in the SAP back end.
I use the following bapis to get these informations :
- HRWPC_RFC_GET_COL_INFO (returns columns informations)
- HRWPC_RFC_GET_OBJECTS (returns employees personal numbers -> pernr)
Fact is the second one doesn't return as much informations as needed.
So I have then to call a third bapi :
- MYBAPI_USER_INFOS (return informations about an employee)
which, from an employee pernr, returns a lot more informations about him.
Fact is I manage to use efficiently both first bapis, so I get columns and pernr data.
Then I would like to get in a context node the list of enhanced informations of the employees, which is mapped to my view context and applied to a dynamic table.
My problem :
While adding programmaticaly the columns to my context node, I get the following exception : "com.sap.tc.webdynpro.progmodel.context.ContextException: Node(TeamViewerApp.MainViewColumns): cannot bind or add element, because it is already bound to a node" error.

HI,
com.sap.tc.webdynpro.progmodel.context.ContextException: Node(HrChiefRedressalView.Ctx_FilteredOutput): cannot bind or add element, because it is already bound to a node
Try to bind or add element from the source of the node instead of mapped one.
Ex:
Controller->View
If your node is mapped from controller to view. bind/add element should be done at controller level not at view level.

Type (..) of the context element (..) in view (..) does not exist

Hi all
I have got an question. I have an ABAP webdynpro with a context node which is connected to an ABAP structure.
The context node is mapped to a context node of a view and the fields of the view are mapped to the context node of the view. So the data is send through them. That works fine.
Within this ABAP structure i have added 3 extra new fields. After creating them i activated the structure.
Within the webdynpro i have updated the context mapping between the node and the structure and also between the different mappings between the views and the componentcontroller where this node is used,
Within the context tab of all the views i see all the three new fields.
When i try to map those fields to a field in the screen it cannot be done. i get the following message:
Type (..) of the context element (..) in view (..) does not exist
Anf the new fields are gray.
Does anybody know the solution for this?
kind regards,
Anton Pierhagen

Hi all
Thanks for all of the replies. But unfortunately the right answer wasn't there.
I had tried to map the structure and re-create the node on several levels in my web-dynpro, but there was no change after this changes.
When i created an own dataelement and an own domain in my ABAP structure, it worked.
I could select them in the webdynpro. But why????
i still not get it..
But thanks for the replies!
Kind regards,
Anton Pierhagen

Select Option's Context Element for the REPORT_ATTRIBUTE_ERROR_MESSAGE

Hi,
We're on 7.0 ehp1.
I found a thread on same subject u201Cwdr:select_options and highlight Error Message with a Link to Inputfield u201C, Jul-23-2008, in which Thomas Jung gave an explanation of how to get the context element of the Select Options on a view.
I tried to follow it, but Iu2019m still not getting it. Please show how to get the context element of a Select Option for the u201CREPORT_ATTRIBUTE_ERROR_MESSAGEu201D .
 wd_comp_controller->go_message_manager->report_attribute_error_message(
 exporting
 message_text = ls_messaga_text
 element = ?????
 attribute_name = ls_option_id
Thomas' explanation:
I gave you the code that gets you to the interface controller. From there you call the GET_API to get the component controller. After you have the component controller it is normal context coding to read the context of the Select-Options context. Run the debugger and use the Web Dynpro view to see what your context looks like at runtime. When I test this with one of my applications, the names of the context nodes that were dynamically generated was really straight forward - as it uses the names of the select-option itself. Nothing special once you reach this point - just normal context coding...."

Huntr

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

Issue in the PDF at the time of Using current context element

Experts,
For retrieving the values in the WebDypro applications, I have used the current context element. Using that current context element I have generated the PDF.
I have faced critical issue, if the two different persons are accessing the same PDF button at a same time in the different system.
Both of them have selected the different values in the table (different id). But in the output it displays the same results (same id) for both the persons.
The PDF displays the correct results (different id) at different time interval for both the persons.
We are facing this issue, only if both the persons are clicking the PDF button at the same time.
Could you please anyone give the solution for this problem?
Application developed using WebDynpro Java NW2004

Context elements renaming

I had created one Interactive Adobe form earlier.
Now I am going to its interface and renaming some of the parameters.
I want to know whether this parameters' new names would be automatically reflected in:
a. context of the adobe form
b. all the names of the elements drag and dropped on the interactive form
Or i've to do this activity manually for each and every element renamed.
Is there a way to rename all the elements on the adobe forms to reflect the new names ?
Thanks in anticipation.

Hi Mate,
if you change the interface for new fields in a table type, or data element of a field or field name sort of.
Adobe cant recognize and pickup these changes automatically.
so you need to goto sfp tcode, open the form and refresh the context element by element.
if there are new fields to be added you need to drag and drop only then it reflects.
Cheers,
Sai
