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

       IF entity IS BOUND.
         entity1->set_properties( EXPORTING is_attributes = ls_header1 ).
       ENDIF.
but the problem is both the entity is INITIAL.

How to call jpf controller method from javascript

Can any one help me how to call pageflow controller method from JavaScript.\
Thanks.

Accessing a particular pageflow method from Javascript is directly not possible unless we do some real funky coding in specifying document.myForm.action = xyz...Heres what I tried and it did not work as expected: I found another workaround that I will share with you.
1. In my jsp file when I click a button a call a JavaScript that calls the method that I want in pageflow like this: My method got invoked BUT when that method forwards the jsp, it lost the portal context. I saw my returned jsp only on the browser instead of seeing it inside the portlet on the page of a portal. I just see contents of jsp on full browser screen. I checked the url. This does make the sense. I do not see the url where I will have like test1.portal?_pageLabe=xxx&portlet details etc etc. So this bottom approach will notwork.
document.getElementById("batchForm").action = "/portlets/com/hid/iod/Batches/holdBatch"; // here if you give like test1.portal/pagelable value like complete url...it may work...but not suggested/recommended....
document.getElementById("batchForm").submit;
2. I achieved my requirement using a hidden variable inside my netui:form tag in the jsp. Say for example, I have 3 buttons and all of them should call their own action methods like create, update, delete on pageflow side. But I want these to be called through javascript say for example to do some validation. (I have diff usecase though). So I created a hidden field like ACTION_NAME. I have 3 javascript functions create(), update() etc. These javascripts are called onclick() for these buttons. In thse functions first I set unique value to this hiddent field appropriately. Then submit the form. Note that all 3 buttons now go to same common action in the JPF. The code is like this.
document.getElementById("ACTION_NAME").value = "UPDATE";
document.getElementById("batchForm").submit.
Inside the pageflow common method, I retriev this hidden field value and based on its value, I call one of the above 3 methods in pageflow. This works for me. There may be better solution.
3. Another usecase that I want to share and may be help others also. Most of the time very common usecase is, when we select a item in a drop bos or netui:select, we want to invoke the pageflow action. Say we have 2 dropdown boxes with States and Cities. Anytime States select box is changed, it should go back to server and get new list of Cities for that state. (We can get both states and cities and do all string tokenizer on jsp itself. But inreality as per business needs, we do have to go to server to get dynamic values. Here is the code snippet that I use and it works for all my select boxes onChange event.
This entire lines of code should do what we want.
<netui:anchor action="selectArticleChanged" formSubmit="true" tagId="selectPropertyAction"/>
<netui:select onChange="document.getElementById(lookupIdByTagId('selectPropertyAction',this )).onclick();" dataSource="pageFlow.selectedArticleId" >
<c:forEach items="${requestScope.ALL_ARTICLE}" var="eachArticle">
<%-- workshop:varType="com.hid.iod.forms.IoDProfileArticleRelForm" --%>
<netui:selectOption value="${eachArticle.articleIdAsString}">${eachArticle.articleItemName}</netui:selectOption>
</c:forEach>
</netui:select>
See if you can build along those above lines of code. Any other simpler approches are highly welcome.
Thanks

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 do I call an Application Module method from a EntityImpl class?

Guys and Gals,
Using Studio Edition Version 11.1.1.3.0.
I've got a price update form, that when submitted, takes the part numbers and prices in the form and updates the corresponding Parts' price in the Parts table. Anytime this Parts view object's ReplacementPrice attribute is changed, an application module method needs to be called which updates a whole slew of related view objects. I know you can modify view objects via associations (How do I call an Application Module method from a ViewObjectImpl class? but that's not what I'm trying to do. These AppModuleImpl methods are the hub for all price updates, as many different operations may affect related pricing (base price lists, price buckets, etc) and hence, call the updatePartPricing(key) method.
For some reason, the below code does not call / run / activate the application module's method. The AppModuleDataControl exists and recordPartHistory(key) is registered and public. At runtime, the am.<method> code is simply ignored, and as a weird side-effect, I cannot navigate out of my current page flow.
public void setReplacementPrice(Number value)
    setAttributeInternal(REPLACEMENTPRICE, value);
    AppModuleImpl am = (AppModuleImpl)this.getDBTransaction().findApplicationModule("AppModuleDataControl");
    Key key = new Key(new Object[]
        { getPartNumber() });
    am.recordPartHistory(key); // AppModuleImpl method which records pricing history
    am.updatePartPricing(key); // AppModuleImpl method which updates a whole slew of related pricing tables
}Any ideas?

Thanks Timo.
Turns out the code provided was correct, but the AppModuleImpl method being called was not. A dependent ViewObject wasn't returning the row I was expecting. I then tried to perform some operations on that row, which in turn ... just stopped everything, but didn't give me an error.
It was the lack of the error that threw me off. I had never messed with calling an AppModuleImpl method from the EntityImpl so I assumed that's what was messing up.
You are correct. It is available from the ViewRow, but I thought it better to put it in the EntityImpl. This method will be called every time the replacement cost is modified. If I didn't put it in the EntityImpl, I'd have to remember to call it every time a replacement cost changed.

Call methods from view controller to another (enhanced) view controller!

Dear All,
Is it possible to use/call methods from view controller to another (enhanced) view controller? Iu2019ve created a view using enhancement in standard WD component. I would like to call one method from standard view controller in the enhanced view controller.
Is it possible to include text symbols as enhancement in standard class?
u2026Naddy

Hi,
If you have just enhanced an existing view then you can call the standard methods in one of the new methods which you will create as part of enhancement.
If you have created a totally new view using enhancement framework option ( Create as Enhancement ) then in this new view you won't be able to use existing methods in other view as a view controller is private in nature. So all the view attributes, context nodes and methods are Private to that view only.
Regarding text elements, I guess adding a new text element is just a table entry in text table and is therefore not recorded as enhancement.( Not very sure about this, need to double check )

Calling view controller method from component controller method

Hi,
Is there any way to call view controller method from component controller method?
Thanks,

Hi Khandal.
You should not make you component controller dependent from a view controller.
But what you can do is to define an event in the component controller. The view
controller can register for this event.
In the stage where you currently want to call the view controller method just fire
the event. In the event handler method in the view controller you can call the
method then.
Why do you need to call a view controller method? Can you give more details
about the scenario?
Cheers,
Sascha

How to call the screen in methods could u please explain

hi,
how to call the screen in methods could u please explain clearly with example

HI ,
CALL SCREEN - Call a screen
Basic form
CALL SCREEN scr.
Addition:
... STARTING AT x1 y1 ... ENDING AT x2 y2
Effect
Calls the screen scr; scr is the number of a screen of the main program. You use SET SCREEN 0. or LEAVE SCREEN. to define the return from the CALL screen.
Note
Please consult Data Area and Modularization Unit Organization documentation as well.
Addition
... STARTING AT x1 y1 ENDING AT x2 y2
Effect
The coordinates x1, y1 (start column and start line in the window) and x2, y2 (end column and end line in the window) define the size and position of the CALL screen ("top left - bottom right"). Besides these coordinates, you can also see the contents of the primary window, but cannot perform any action there.
Note
If "ENDING AT ..." is not specified, suitable values are substituted for x2 and y2, taking into account the size of the called screen.
Exceptions
Non-Catchable Exceptions
Cause: No further screen level (call screen); the maximum number of nested screen levels is restricted to 50 at present.
Runtime Error: DYNP_TOO_MANY_CALL_SCREENS

Call Java Class and Methods from ABAP

Hi
I install de JCo, But how i can call java class and methods from ABAP?. somebody has an example?
The tutorial say that's is possible, but don't explain how do that?
Thanks.
Angel G. Hurtado

If you need only simple java program, you do not need to install JCo. The following codes can call java class.
DATA: COMMAND TYPE STRING VALUE 'C:\j2sdk1.4.2_08\bin\java',
      DIR TYPE STRING VALUE D:\eclipse\workspace',
      PARAMETER TYPE STRING VALUE 'Helloworld'. "here the name of your java program
CALL METHOD CL_GUI_FRONTEND_SERVICES=>EXECUTE
   EXPORTING
     APPLICATION = COMMAND
     PARAMETER = PARAMETER
     DEFAULT_DIRECTORY = DIR
   MAXIMIZED =
     MINIMIZED = 'X'     "If you need the DOS window to be minimized
EXCEPTIONS
    CNTL_ERROR = 1
    ERROR_NO_GUI = 2
    BAD_PARAMETER = 3
    FILE_NOT_FOUND = 4
    PATH_NOT_FOUND = 5
    FILE_EXTENSION_UNKNOWN = 6
    ERROR_EXECUTE_FAILED = 7
    OTHERS = 8.
Tell me if it works.

Urgent!! How to call a custom transaction or an ABAP program in BSP?

Urgent!! How to call a custom transaction or an ABAP program in BSP?
We are pretty new on BSP. Would be very appreciated if any expert here give us the detailed steps on how to build up the application to just call a custom transaction (e.g., t-code: ztest) or an ABAP program. Would we have to create a button or event handler to do that? And the detailed steps?
Thanks in advance and we will definately give you reward points!

hi Durairaj,
During the time to wait for your answer, we copied Bernd's code from your last link, but when activating it, get the 1st error msg:
Field "CLIENT" is unknown. It is neither in one of the specified tables nor defined by a "DATA" statement. "DATA" statement."DATA" statement. The error shows up here:
<td>
<htmlb:inputField id = "client"
value = "<%= client %>" />
</td>
Then we added Client to the page attribute and define it as type String, then get another error:
The field "EVENT" is unknown, but there is a field with the similar name "EVENT_ID"."EVENT_ID". This error shows up at the beginning in the Event Handler:
OnInputProcessing:
code
event handler for checking and processing user input and
for defining navigation
event handler for data retrieval
event = cl_htmlb_manager=>get_event( runtime->server->request ).
IF event->name = 'button' AND event->event_type = 'click'.
button_event ?= event.
How to resolve this unknown Event error, need to define in Page Attribute tab? but with what type?
Actually we only want to run an ABAP4 program in BSP, the code is complicated, could you show us an easy way of doing this in BSP?
