Get controller from view

Is there an automatic way from within a view to get the controller that is managing that view? Or do I need to setup outlets etc and configure them in the init phase?

In most cases it would be the File's Owner. NSWindowController has an owner: method, but UIViewController does not. You might be able to get it from NSNib's NSNibOwner constant?

Calling methods in controller from View.

Hi Experts,
Can any one let me know or point to the document which explains how to call a userdefined method in component controller from view.
Thanks,
James

You have to define a "controller usage" using the controller editor. Then the code generator will create an accessor "wdGet<ControllerName>Controller()" to the component controller which can be used to call its methods.

Access context of Component Controller from Views

Hi,
In WD Java, I used to set attributes value for Context present in Component controller from the view. I used to write a piece of code at the view level for this.
How do i do this in WD ABAP. I believ I have to get instance of Component controller like this:
lr_compcontroller type REF TO ig_componentcontroller.
lr_compcontroller = wd_this->get_componentcontroller_ctr( ).
Regards,
Murali.

Hi Murali,
yes you can access the comp_controller in the same sort of way in WDA.
You declared component usages on the property tab.
The wizard (ctrl-F7)has various options, check it out.
One is calling methods on declared controller usages.
the result is for example such generated code:
DATA: l_ref_ANOTHER_CONTROLLER TYPE REF TO IG_ANOTHER_CONTROLLER .
l_ref_ANOTHER_CONTROLLER = wd_This->Get_Another_Controller_Ctr( ).
data:
l_Api_Another_Controller type ref to IF_WD_CONTROLLER.
See also local interface code in CTRL-SHIFT F1.
You work directly with this info. Indeed constants from the interfaces should be used this way.
Work with the wizard. And declare all usages in the properties tab.
Moving outside of the framework is possible but not recommended
regards
Phil

Reference to Custome Controller from View controller

Hi all,
I have created a custom controller and inside that i have a method. i need to execute that method from a view controller, similar to executing a method in the component controller. to execute a method in the component controller i use the WD_COMP_CONTROLLER attribute to refer to the component controller. similarly how to i refer my custom controller from the view, or is there any other way? it would be great if someone can help me with this.
Malinda

hi,
Lets say view1 has the event ONACTIONNAVIGATE and you want to call a method 'start_navigation' in the custom controller named 'navigation'.
Use the following code.
METHOD onactionnavigate .
DATA lo_navigation_controller TYPE REF TO ig_navigation.
lo_navigation_controller = wd_this->get_navigation_ctr( ).
CASE navigation_type.
    WHEN 'BACKWARD'.
      lo_navigation_controller->start_navigation( if_fitv_fpm_api=>gc_navigate_backward ).
    WHEN 'FORWARD'.
      lo_navigation_controller->start_navigation( if_fitv_fpm_api=>gc_navigate_forward ).
ENDCASE.
ENDMETHOD.

Method in custom controller not getting called from view

Hi experts,
I have a very strange problem. My web dynpro application works fine on the development portal. i am in the process of deploying to the production portal there is no issue it deploys perfectly without any problems. However i have noticed that some methods in my custom controlller which are called from the view do not run. there is no error message or anything data just doesnt get picked because the execute function which fills the context are in the custom controller methods.
For some reason the method in the custom controller does not get called even though i'm calling it for the view. I have this problem with two methods. the other methods work without any issue.
Now i overwrote what i have on production at the moment so am stuck and in need for a solution.
I have tried undeplying, restarting and re-deploying to no avail. what could be wrong?
thanks and regards,
dilanke

Deal all
This is the code. basically im calling it from the plug on the detail screen.
This is the method that doesnt get called anymore.
wdThis.wdGetGetPurchaseOrderCustController().getPODetail();
The reportSuccess() works fine.

Dilanke
public void onPlugFromListView(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

Using EL to get values from View Objects

Hello again!
I' m using jdev 11.1.1.4.0, with adf and business components
Is there any way i can get a value to an af:outputText from a view object's field without
a) having to expose all fields that I need in bindings tab?
b) having to declare all fields to a backing bean
I have a statistical table with about 30 numbers in a record and it would make my project impossible to follow!
Some EL on the af:outputText with a parameter to a function on my backing bean, would sound perfect, but I've read that it's impossible...
Any clues?
Thank you for your efforts!
Nikos

I did not understand you.
will the drag and drop your attribute on your page will solve your problem?
or do you need to create attributeValues biding for single attribute? if yes do the following:
1- From your page, right click and select Go to Page Definition.
2- From the binding section, click the plus green icon to create a new control biding, and choose attributeValues from the list.
3- select your data source from the list or create a new one, then select the attribute you need.
4- now you have a biding, and you can set the value for your output text.
value =#{biding.yourAttribute.inputValue}

Function module get tables from view

Getting data from view object into backing bean

Hi,
My requirement is explained below -
I have a ADF editable table in a jsf page which is connected to backend database table. In the table there are 6 columns and only 2 are editable. So when user inputs a value in first input column an event is triggered such that the data for all the remaining columns should be fetched from another database table.
Typically if we are not using ADF development environment. We would have had a simple business method which creates the sql query by taking the input from textbox with simple where clause and I would have got the data. I am not getting any idea how to do this in ADF. I have the second table as view object but how to access the view object from backing bean and get data based on the input given.

Hi,
step 1) Expose a method on the ViewObject Impl class
step 2) define arguments for the method as needed to identify the row to read data from
step 3) retrieve the row from the VO that holds the data you want to add and return a HashMap with this information
step 4) expose the method on the client interface (Java menu selection on the View Object)
step 5) In the PageDef file, create a method binding to the method you exposed on the ViewObjectImpl
step 6) Call the method binding from the managed bean like
OperationBinding getDataFromVO = (OperationBinding) BindingContext.getCurrent().getCurrentBindingsEntry().get("Name of method binding);
getDataFromVO.getParamsMap().put("name of arguments1", value1);
getDataFromVO.getParamsMap().put("name of arguments2", value2);
Object retData = getDataFromVO.execute();
if(retData != null && getDataFromVO.getErrors().size()==0){
HashMap retDataMap = (HashMap) retData;
... follow the rest of your logic ....

How to get data from another view on the RFx to populate bidders web dynpro

i am trying to populate bidders in the table on the bidder tab when a user click a button based on the line item data. How do i have access to get the line item since it is in a separate component controller and view for the RFx? thanks you.

Hi,
You mean Data transfer between two components..
To pass the value from one component to other component, you can use used component scenario.
For example let use assume we have two comp ..
Comp A,
Comp B.
now we need to pass the value from Comp A to Comp B.
Then declare the Comp A as used component in Comp B.
Now then you can create a node in the comp A component controller and check the interface check box there then the
node and the attribute will be present in the interface controller also .
and this interface controller context you can access in the component and map it to view there and display it.

How to access a Java class from view controller?

I getting this error "Test cannot be resolved or is not a type".
How do I fix this?
Thanks

After this you can goto the context of your View and define the VA goto the type of VA and click on the right side button and go to java native type and type your java file name click you name .
that means the jave file s assigned to VA.
U can utilize thrut that VA.

Can we get data from business views in CR 2008/XI?

Hi All,
Can we get data from business views in CR 2008/XI?
If its possible, pls let us know how to get connect with Business View in both of these versions and what is the tool that we have to use to create Business Views.
Thank you,
Krishna Pingali

Hi Krishna,
Crystal Reports/BusinessObjects Enterprise ( BOE ) Business Views can only be created using the BV build which comes with BOE and installed using the Work Station installer for BOE. for both XI and 2008.
You cannot mix these two versions on the same PC not can one talk to the other, the BV designer must match the same version as BOE. XI ( version 11.0 ) is no longer available but if you mean XI R2 ( version 11.5 ) then it still is.
It's not completely clear which Business View you are referring to? BOE has a Business View Designer so not sure if this is just a naming problem or not? If you are referring to the BOE Business View Designer then the above is true. If your reference is about some other BV designer or data source then you need to clarify.
Contact our Sales department for pricing and availability.
Thank you
