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");

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.

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

How to access the controller method from javascript onclick event?

Hi All,
I am totally new to development. And I got struck in calling a controller method from javascript function.
I have no idea about ajax and all those things. Please can anyone help me to solve this issue!
Thanks in advance.

Hi,
As I know, you can use jQuery to do this, here is an example.
Example of your Controller Method.
[HttpPost] // can be HttpGet
public ActionResult Test(string id)
bool isValid = yourcheckmethod(); //.. check
var obj = new {
valid = isValid
return Json(obj);
and this would be your javascript function.
function checkValidId(checkId)
$.ajax({
url: 'controllerName/Test',
type: 'POST',
contentType: 'application/json;',
data: JSON.stringify({ id: checkId }),
success: function (valid)
if(valid) { //show that id is valid }
else { //show that id is not valid }
If you have further issues, I would suggest you move to MVC forum, it is appropriate and more experts will assist you.

How to get the alert context from scom event into incident description?

Hello,
I user SCO for creating incidents of SCOM events. My problem ist that in some events the most interesting information is standing in AlertContext. But I cannot add this text to the descritipn field of our incident tool. If I user the published variable Context
from MonitorAlert the creating of the incident fails. The right information is standing in the Params field of the Context content. But if I add the Params variable from MonitorAlert there is not the content given.
So how can I add the AlertContext information in my incident content?

Hi,
I use the Publish Data Context from "Get Alert" and the xpath-Query below to get the short name of the service if Alert is "Windows service stopped".
I think it's difficult to have a default Query because the Context is too various fot all OpsMgr Alerts.

Removing the dynamic attributes from view context

Hi,
I have added an attribute dynamically using the following line of code in wdDoModifyView():
wdThis.wdGetContext().getContext().getRootNodeInfo ().addAttribute(<attributename>, <datatype>);
Now I want to remove the dynamically created attribute from the context.
Pls suggest me in this regard.
Regards,
Ramesh.

Hi Ramesh,
You can use the following code to remove the attribute dynamically:
Iterator itr = wdContext.node<NodeName>().getNodeInfo().iterateAttributes();
// If the node where you are making these attributes is a context node then just do:
// wdContext.getNodeInfo().iterateAttributes(), for iterator
while(itr.hasNext()){
IWDAttributeInfo attrInfo = (IWDAttributeInfo)itr.next();
attrInfo.remove();
This will solve your problem.

Pravesh

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 Remove the Entity usage from View object at runtime

Hi,
A ViewObject can be created dynamically based on the Existing ViewObject Defintions. The newly created dynamic ViewObject will have all the defintion including Attributes, its structure along wtih Entity usage of the existing ViewObject definition.
My requirement is i don't want to have the Entity usage alone whereas Remaining structure need to be retained.
Can any body suggest on how to do it.
regards.

Hi,
design time or runtime? At designtime, have you tried to just remove the entity reference? Given the disadvantage of removing the entity (and the changed behavior associated with it) what is the use case for which you want to disable the entity reference?

Hi Carsten,
Thank you for the detailed feedback.
I want the fields ID_TYPE & ID_TYPE_DESCRIPTION from IUICMD/SearchAccount to be available in IUICMD/DetailAccount. I have created a context node u201CSEARCHu201D in view IUICMD/DetailAccount. I have created the context node with out choosing u201CCreate with Instanceu201D. This Context node (SEARCH) is already available in IUICMD/SearchAccount as part of the standard.
Below given is contents of the Method CREATE_SEARCH of my context class ZL_IUICMD_DETAILACCOUNT_CTXT of view IUICMD/DetailAccount, which is created by the Wizard during enhancement.
method CREATE_SEARCH.
    DATA:
      model        TYPE REF TO if_bsp_model,
      coll_wrapper TYPE REF TO cl_bsp_wd_collection_wrapper,
      entity       TYPE REF TO cl_crm_bol_entity,    "#EC *
      entity_col   TYPE REF TO if_bol_entity_col.    "#EC *
    model = owner->create_model(
        class_name     = 'ZL_IUICMD_DETAILACCOUNT_CN00'
        model_id       = 'SEARCH' ). "#EC NOTEXT
    SEARCH ?= model.
    CLEAR model.
bind to custom controller
owner->do_context_node_binding(
           iv_controller_type = CL_BSP_WD_CONTROLLER=>CO_TYPE_CUSTOM
           iv_name = 'IUICMD/CuCoMD' "#EC NOTEXT
           iv_target_node_name = 'BUILHEADERSEARCH'
           iv_node_2_bind = SEARCH ).
endmethod.
I have enhanced the Custom Controller. Now it have new implementation class u201CZL_IUICMD_CUCOMD_IMPLu201D
Let me know where I am doing mistake
Thanks in advance
