Custom controller context value attribute

Hello,
I have a custom controller with one value attribute. In the wdDoInit() method of the custom controller I can not access this attribute using:
wdContext.currentContextElement().setAttrib()
Why?
The same works without any problems using the component controller instead of the custom controller.
Thanks, cheers,
Felix

Hi,
I have created the custom controller and within that I have created the attribute.
Now I am able to access the attribute by using thr same code.
wdContext.currentContextElement().setAge(" ");
After creation of custom controller you just save all metadata. Then check it.
I think you will get the attribute.
Thanks

Sending controller context value attributes to web service model

Hi,
I have put some parameters (value Attributes) in controller context and mapped to different views. Is there any way by which i can send the values to the web service model , each time the web service is called? like through header or some thing like that??

Hi Sujesh,
Read those value attributes in your controller using following code:
wdcontext.currentContextElement().get<attribute>();
and then set these value in your web service model.
<model name> model = new <model name>();
model.set<attribute>(<value>);
wdcontext.node<nodename of your web service model>().bind(model);
wdcontext.current<nodename of your web service model>element().modelobject().execute();

How to map single context value attribute to multiple value attributes?

Hello,
is there any way to map a single value attribute
from view's context into several value attributes
in controller's context?
The business context of what I want to achieve
is the following: I have a view which can be called
in two modes: read only (RO) and read-write (RW).
The input parameters to the view are the same for
both modes, however when in RO mode, the view calls
a different set of web services than when called
in RW mode. Before calling each of the web services
I need to populate their context value attributes
with appropriate input values.
I know I can do it in Java code, but is it possible
to do it without any programming (doing it in the
source code is prone to errors)?
Any help highly appreciated.
Greetings,
Tomek.

Hi Kishore,
than you very much for your kind help.
I have already created a value attribute of type
boolean and mapped it into the read-only property
of the UI elements. This however does not solve all
of the problems... I will describe it with an
example:
Let's say the form I want to implement will be
used to: create (read-write mode), update (read-
write mode) or show (read-only mode) customer's
data. The customer's data is complex (lots of
data, including tree structures).
The problem is that:
- when the form is called in read-only mode,
it should populate its fields with values
provided by the getCustomerData web service,
- when the form is called to create a new
customer (in read-write) mode, it should
not use the getCustomerData web service.
Instead it should map the input values
entered by the user into input parameters
of the createNewCustomer web service,
- when the form is called to update customer's
data, it should first display values returned
by the getCustomerData web service, and then
it should map the modified values entered by
the user into input parameters of the
updateCustomer web service,
In all the above cases I must map my view's
context data to different controller's context
elements. Doing it directly in the source code
is not a nice solution. Is there any other
way to achieve this?
Calling a form in different modes in not an
unusual thing, so I was hoping that maybe
there are any built-in mechanisms that would
solve the obove problem...
Greetings,
Tomek.

Interface Controller context model attribute error

I am trying to create a controller interface as such: I created a DC that goes out and retrieves SAP ID using a RFC call. My controller context is bound to a RFC model. I'd like to expose the SAP ID that comes back from that call within a model attribute to other components. I try to create a model node and corresponding model attribute within the Interface Controller, setting the isInputElement = true. However, as soon as I do this I get a number of compile errors:
"The context model node has not been bound to a model class", "The context model attribute has not been bound to a model property".
Are you not allowed to map model nodes to an interface?

Karla,
First, set isInputElement to false. Think again, you are exposint "result" outside but not collecting "input" from outer component.
Next, calculated attributes to the rescue here.
Say, in component controller you have 1..1 / 0..1 model node SapIdQuery_Input with 1..1/0..1 child SapIdQuery_Output that holds System_Id attribute, type string.
Now create in component controller context (right below root node) attribute System_Id of type string, set read-only to true and calculated to true. Switch to source editor and write the following for generated attribute "getter":
if (wdContext.currentSapIdQuery_InputElement() != null &&
 wdContext.currentSapIdQuery_OutputElement() != null)
return (String)wdContext
 .currentSapIdQuery_OutputElement()
 .getAttributeValue("System_Id");
else
return null;
Now add controller usage (of component controller) in interface controller and map attribute in interface controller to calculated attribute in component controller.
If you expirienced problems with mapping, try to create calculated attribute in 1..1 subnode of root context node.

Need to bind value attributes of Component controller with value attributes

Hi,
I am developing a Java Web Dynpro application which is importing RFC Model.

Hi Kaushik,
It is very simple to enter values in webdynpro and to update the ztable through RFC
All you hav to do is
1. Create the ztable , RFC to import data into that table,
2. Create the model in webdynpro with that RFC
3. First map the ModelInputElements to the component controller(say zid, zname) (you can have your own value attribute in component controller say id , name )
4. Map the attributes to the view where the input field is there
5. Now write the code as follows,
Zxxx in = new Zxxx();
wdContext.nodeZxx_InputElement.bind(in);
in.setZid(wdcontext.currentContextElement().getId()); // getId component controllers attribute and getZid is model' s mapped attributre
in.setZname(wdcontext.currentContextElement().getName()); // getName component controllers attribute and getZname is model's mapped attributre
/* u need not have to map that model attrobute to component attribute for that */
try
in.execute();
Catch(Eception e)
e.printStackTrace();

Custom controller causes DFF attribute values to be overwritten when usinf

Hi,
I have customised an Oracle seeded controller to handle the DFF field for the ReadOnly property.
have used BoundValueUtil.bindReadOnlyAttr(flex, "MSSupReadOnly").
There are 3 DFF field but for some reason if there are 2 lines on that page and I update one line one of the DFF segment values gets updated on the other and the value on that line is overwritten.If I remove the customization it works fine and it happens just for 1 field I am handling another DFF segemnt same way but it works fine.
i also tried using
flex1.setAttributeValue(OAWebBeanConstants.READ_ONLY_ATTR,new OADataBoundValueViewObject(flex1, "MSSupItemReadOnly"));

Put some debugging statements in the code and follow the processing logic. That should give you some idea on where its getting wrong.

Values not passing from form to context attributes (value attributes)

Hi Experts,
I have bound the properties of theadobe interactive form (WD-Java) to the context attributes but the values are not passing to the value attributes at runtime.
For your information I have not bound the pdfsource binary attribute of the view to the custom controller pdfsource binary attribute.
Please advise.
Thanks,

Context
   GetData - ModelNode mapped to controller context (DataSource)
         Attribute1 - Value Attribute (Form Field)
Is it allright to have the Data Source as a ModelNode (mapped to the controller context node) and then have Value Attributes under the ModelNode which are then bound to the adobe form input fields.
I know its frustrating to advise on such questions without looking at the code actually. But I would definitely need your support.
If possible could you mail me a project of yours where you have the form being PREFILLED with some values coming from a RFC FM and then the same form gets posted to SAP though another RFC FM.
Thanks,
[email protected]
OK. When I create a Fresh Adobe Interactive Form application, it works fine.
The problem Im facing is in the case, when Im using an existing PDF file created in the ABAP stack (TCode SFP). I am importing this PDF file into the WebDynpro Java Application and then binding the fields. So in this case the context binding does not work.
You guyz are right, I need to check if there is any other script which exists. But still what are views after this update?

Can i Bind more than one Model object to the Custom controller or not

Hi All, I trying to bind more than one model object to the custom controller, Both the model objects contains same attribute name called ( output). Both model objects created on to top of the BAPI. So when i bind first model object to the custom controller will work fine. When i am trying to bind the second model object to the same controller. This second model object also having the same attribute name called "output" . So it is giving an error of "Duplicate context element "Detail". Rename or uncheck duplicate elements.
can i assign more than one model object to the single controller or not?
But in the reference document, it has given that , we can create model object with more than one bapi.So in this case if both the bapis contains any element with the same name will also be problem. Any body give me the solution.
Initially we have created one custom controller for each model object. But later i realized that, why con't we use same controller for all the model object. Because, the custom controller context is the public context. this context shared across all the view controllers.
The concept which I am trying to do is right or wrong?

Hi Vishal,
of course, you can bind one controler to many models. When the same name occours you can simply RENAME binded node in controler.

How to call a custom controller method from view

Hi,
I ve created a simple web service and consumed it in a model. Mapped the input & output parameters to custom controller context which in turn mapped to component controller's context which in turn to view's contexts.
How to call a custom controller method from view?
Please explain the syntax.
Regards,
Manoj.

Hi Patralekha,
Give some idea for the below scenario:
I ve created a simple web service and consumed it in a model. What I did was
1) for the input parameters, mapped the node from view->custom controller->model
2)for the output parameter, mapping from model->custom controller->view.
It works fine.
But I don't want to access model nodes directly, rather I want to set the input param in somewhere else (like custom controller) before calling the appropriate method, same for the response also.
Share me your thoughts.

Manoj.

Self defined type how to create value attribute

Hello!
How can I create a new context "value attribute" if its
type is doesn't exist in the drop down list
where you can choose either a primitive data types
or a java Type. It is an self defined class.
It's name is "Notebook". I want to bind all the Notebooks
with a value attribute. The method returns a Notebooks-Array.
How can I deal in such cases?

Hi,
You need to put your java file inside src-->your package. As you said it is already there, then try to reload and rebuild your project. It must show in the java native types when you browse.
Even check the package statement of your java file.

Create Partial Fire action on DFF context value in controller extension

Hi All,
I have a requirement where I will have to default the DFF attribute value based on the context value chosen in the same DFF.
Since the page is a seeded page i have done that using Controller Extension.
I have followed the below steps.
1.I have created one class file XXR2R_AR_BANK_ACCT_EXTCO
2. In that file I have written the following piece of code
+public class XXR2R_AR_BANK_ACCT_EXTCO extends UpdateExtBankAcctCO {+
public void processRequest(OAPageContext oapageContext,
OAWebBean webBean)
+{+
super.processRequest(oapageContext, webBean);
OADescriptiveFlexBean dfb =
+(OADescriptiveFlexBean)webBean.findChildRecursive("FlexField");+ // This is the ID of the flexfield defined in seeded page
FireAction firePartialAction = new FirePartialAction("contextvalchng");
+}+
public void processFormRequest(OAPageContext pageContext,OAWebBean webBean)
+{+
super.processFormRequest(pageContext, webBean);
if ("contextvalchng".equals(pageContext.getParameter(OAWebBeanConstants.EVENT_PARAM)))
+{+
super.processFormRequest(pageContext, webBean);
OADescriptiveFlexBean dffBean =
+(OADescriptiveFlexBean)webBean.findChildRecursive("FlexField");+
OAApplicationModule am = pageContext.getApplicationModule(webBean);
OAViewObject extVO =
+(OAViewObject)am.findViewObject("ExtBankAccountsVO");+ *// This is the view name corresponding to the DFF fields*
String str = "" ;
OARow row = null;
if (extVO!=null)
+{+
row = (OARow) extVO.getCurrentRow();
if (row!=null)
+{+
str = (String)row.getAttribute("ATTRIBUTE_CATEGORY"); *// here I have retrieved the context value of the DFF*
+}+
+}+
dffBean.processFlex(pageContext);
if ("DEN".equals(str)) *// if the context value is "DEN" then only the defaulting will be done*
+{+
OAMessageTextInputBean mnum = (OAMessageTextInputBean)webBean.findChildRecursive("FlexField1");
mnum.setText("599956");
row.setAttribute("ATTRIBUTE13","6995");
+}+
3. After compiling the .jave file I have placed the .class file in the CUSTOM_JAVA_TOP location and in the seeded page I have placed this CUSTOM_JAVA_TOP top path (in the personalize page section)exactly in the same way where the .class file is.
But when I am changing the context value in the DFF nothing is actually happening.It is never including the custom file behavior.
Please let me know if I am wrong in my coding or my approach.
Thanks
Sudie

Hi,
I think you need to set PPR on one of the segment of the DFF. Following is the code snippet I found few days back in forum. Use this in processRequest() method to set the PPR.
OADescriptiveFlexBean oadescriptiveflexbean = (OADescriptiveFlexBean)webBean.findIndexedChildRecursive("ASNPrdtAddInfoFF"); //DFF ID...in your case it is "FlexField"
if(null != oadescriptiveflexbean)
 oadescriptiveflexbean.processFlex(pageContext);
 //oadescriptiveflexbean.setFlexTableRendered(false); -- useful, if we want to render the items on our own.
 int cnt = oadescriptiveflexbean.getIndexedChildCount(pageContext.getRenderingContext());
 for(int i=0; i<cnt; i++)
 OAWebBean uiNode = (OAWebBean)oadescriptiveflexbean.getIndexedChild(pageContext.getRenderingContext(),i);
 if(null != uiNode && uiNode instanceof OAMessageTextInputBean )
 System.out.println(i + "::::" + uiNode.getLabel() + "::::" + uiNode.getUINodeName()+ "\n");
 if(uiNode.getUINodeName().equalsIgnoreCase("ASNPrdtAddInfoFF2")) //Segment ID...you need to find it out..on which segment you want to do PPR
 FireAction firePartialAction = new FirePartialAction("Event.termChangeEvent", true); //This is I am not sure but it must be the event name
 uiNode.setAttributeValue(PRIMARY_CLIENT_ACTION_ATTR,firePartialAction);
Now you need to check for this event in processFormRequest() method. If this event fetched iterate the Vo rows and check the Attribute value there. if the value matched then do the defaulting process.
Hope this helps..

Mukesh Uchaniya
