Unable to access Component Controller attributes from Views.

Hi,
I am unable to access the attributes in component controller from methods in View even by using WD_COMP_CONTROLLER.
Say, I want to access the attribute G_FLAG in component controller from a method in the View Controller by the following code :
WD_COMP_CONTROLLER->G_FLAG = 2.
Then an error message is showing up saying - Field G_FLAG is unknown. It is neither in one of the specified tables nor defined by a DATA statement.
What should I do? Plz suggest..

Hi,
Please check the Public check box of the attribute in the component controller.
Hopefully it will solve your problem.
Thanks

How to call Custom or Component Controller methods from View Controller

Hy Guys,
how do I call Custom Controller or Component controller methods from a View or Context Controlller?
thanks in advance
Jürgen

Hi Juergen
Yes it is possible, pls follow the below approach to access the component controller in context node class
1) since the standard component controller class is protect variable , declare a variable of type component controller in your controller class.
say for example the public variable you declared is g_comp_controller
2) now redefine the controller class method WD_CREATE_CONTEXT and add the below lines of code
   g_comp_controller ?= me->comp_controller.
3) go to context node class (CNXX) there declare the varaible which of type controller class (IMPL) as public variable, for example g_owner
4) redefine the method IF_BSP_MODEL~INIT and write the below code
     CALL METHOD super->if_bsp_model~init
    EXPORTING
      id    = id
      owner = owner.
g_owner ?= owner.
5) now the variable   g_owner that is declared in (CNXX)   contains reference to your controller class
6) in on_new_focus method access your component controller in the below manner and access the entities also.
DATA: lv_owner                    TYPE REF TO xxxxx_impl, " Implementation class
             lr_comp_cont                TYPE REF TO xxxx_bspwdcomponen_impl, " component controller class
             lv_entity type ref to cl_crm_bol_entity.
lv_owner ?= g_owner.
lr_comp_cont    ?= lv_owner->g_comp_controller.
IF lr_comp_cont IS BOUND.
   lv_entity ?= lr_comp_cont->typed_context->mdfcampaign->collection_wrapper->get_current( ).
now lv_entity contains the value of component controller context node.
Thanks & Regards

Call component controller method from view

Hi
I have created an action in view Thus its event handler is "OnActionDoSomething()"
And, I have a method in component controller "MethodSaySomething()".
Now, how can I call MethodSaySomething() from OnActionDoSomething().
OnActionDoSomething()
// Call MethodSaySomething() defined in component controller
Thanks

Hi,
To access the methods present in component controller from View , first u need to add the component controller as the required controller.
open the view controller --> switch to propertues tab --> add the component controller as required controller(click add controller).
Now in your action handler , write this below code to add the method:
wdThis.wdGet<COmponent Controller>().MethodSaySomething();
Hope it helps
Thanks and Regards,

Calling comp controller attribute from iinside view

HI all,
I want to know how to call a component controller attribute from inside a View's method?
any sampe coding..?
Regards,
Shanthi

Well, you can use the wizard. Just call any method from the component controller. The wizard will create you the code including the line how you will get a reference to the component controller, which is the point here.
After you have the reference to the component controller, let's say lo_component_controller, you can access its attributes like this:
lo_component_controller->your_attribute
Then of course delete the unnecessary lines of code.

Accessing component controller node

Hi..Experts,
How to access component controller node from WINDOW (please give me a sample code ) .
I want to set data to component controller node.
please help me.
Regards,
Siva

Hi siva,
Its very easy u need not to do any extra coding to share data between window context and component controller context.
Step 1) u create the node in component controller and map this node with window context.
step 2) Now in any method of window u write the set_attribute or bind_table statement ,your data will automatically transported to component controller .
So u dont need to do any extra coding for this.
Hope this will help your requirement.

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

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.

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.
Regards,
Manoj.

Accesss the Controller Context from View

Hi,
could you please let me know the code to access the Component Controllers Context from View Controller

Hi Raghava,
Suppose the following structure is there is Component Controller.
Vn_DummyNode
- Va_DummyContext
To access it from the View Controller, you have to add the Component Controller in the required list of controllers.
You can access it using the below piece of code
wdThis.wdGetViewControllerName().wdGetAPI().getContext().getRootNode().getChildNode("Vn_DummyNode", 0).getCurrentElement().getAttributeValue("Va_DummyContext");

Unable to find matching navigation case from view ID. Error 404

Hi All,
I basically wanted to jumpstart my ADF exploration so I am following the tutorial at this link. [http://www.oracle.com/technetwork/developer-tools/jdev/ccset22-all-099343.html]
Everything looks good but when I click the Edit Button, I am encountering an error. What I did was I change the logging mechanism into a FINER in my WLS and from the logs,
it prints below messages.

Unable to access LAN behind RV042 from QUICK VPN Client once it connects

Hi,
Very recently, we had implemented Site-to-Site VPN tunnel between two Linksys RV042 4-port VPN routers. Everybody in our remote site is accessing and sharing the data through this tunnel and it is working fine.
Now, we have a plan to implement the same for our mobile clients also. For this, we had followed all the basic configuration procedures and user got connected to Quick VPN tunnel. Here is a problem we had observed. The mobile client user is connected to the tunnel, but unable to access the office LAN from the PC.
What's the problem in configuration? What i have to do?
Thanks

This declaration is not right. There is no element logonuid, you have the attribute inside a node. workset is a node and thats why you can declare that way.
easiest way is to declate
data lv_logonuid type <ddic type> or
data lv_logonuid type wd_this-><node name>-logonuid.
You can also use the code generator in (CTRL +F7 ) to get/set attributes.

Hi Sayan,
component : BP_HEAD
View: BP_HEAD/BPHeadOverview
I have called event EH_ONPOPUP_CLOSED when popup is closed in view BP_HEAD/BPHeadOverview and i get all the values entered in the popup here using below code.
       lr_context_node = gr_popup->get_context_node( iv_cnode_name = 'ZPOPUPCN' ).
       lr_col_wrapper = lr_context_node->collection_wrapper.
       lr_entity = lr_col_wrapper->get_current( ).
       IF lr_entity IS BOUND.
         lr_entity->get_properties( IMPORTING es_attributes = ls_data ).
       ENDIF.
now ls_data contains all the data entered in the popup ie. - firstname, lastname, house_no, street, city, postal code, country.....
