You can define global variables by using a public variable on script-level. Just make sure you define it outside of any class definition. For example if you want to define a global environment, you can create a script Environment.fx and put there your global variables:
public var GLOBAL_VAR1 = 42;You can access this variable from anywhere with:
Environment.GLOBAL_VAR1 = ...

How to access attribute

Hi all,
   I am new to webdynpro for ABAP. How to access the attribute which is directly under the root context.
ex.
Root Context
|
   Name   ---> attribute.
Regards,
Gnid.

Hi Gopi,
Accessing a context element or a context attribute requires to first have a reference to the related context node. The context root node can be accessed by the standard attribute WD_CONTEXT.
To Access a Node Element: After having accessed a context node, the reference to the element at lead selection of this node can be obtained by calling the method get_element( ). Thismethod returns a reference to the element instance of type IF_WD_CONTEXT_ELEMENT. Accessing the Node Element at Lead Selection The element with index n can be accessed using the method get_element( index = n ) .
Once we access the element we can access the attribute by GET_ATTRIBUTE().
Child nodes of the context root node can be identified using the get_child_node( ) method. This method returns a reference to the node instance of type IF_WD_CONTEXT_NODE. The get_child_node( ) method requires the name of the node and, optionally, the index of the element in the parent node to which the desired node instance belongs. In this case, the parent node is the context root, which only ever has one element; therefore, the index parameter is 1 (default = lead selection of parent element).

Suresh

HOW TO ACCESS ATTRIBUTES FROM DIFFERENT VIEW SET

Hi Experts,
How i can access the variables declared in context class from component controller class
and vice-versa.
Thanks & Regards
Ansal

Hi Ansal
You can bind your context node of view to component controller context node and then you can access the data.
You can do this binding by inserting following statements in create_context_node method of your _ctxt class.
owner->do_context_node_binding( iv_controller_type = cl_bsp_wd_controller=>co_type_component
iv_target_node_name = 'BUILHEADER'
iv_node_2_bind = builheader ).

How to Access Attributes of Fields in VARIANT

Hi,
Can anyone let me know how we can access Field attributes of a variant? I need to change and create these attributes dynamically.
Below are the attributes of screen field saved when creating an variant
     Required field                            O
     Switch GPA off                            L
     Save field without values          P
     Selection variable                       L
     Hide field 'BIS'                            N
     Hide field                                    I
     Protect field                               P
    Field name                   Type   P I N L P L O
    P_REPID                        P                               X
    SO_VNAME                  S
For Example
If 'O' is marked as u2018Xu2019 against any field in the variant then it says that this field is OBLIGATORY
I want to access this sort of information of a variant.
Thanks
Rajgopal Dara

Hi RAJ,
Although the question is not so clear, but as far as i understand you want to see the attributes associated with all the fields in your variant. if so then you can go to maintain variant. just go to se38, select variant as radio button and change it. In the variant maintenance screen you can select change attribute of your variant. you can click on that and pass dynamically values (either from some table like TVARV or from program)
Hope this information will be helpful for you.
Cheers !!

How to access attribute value from another VO using groovy?

Hello, I am using JDeveloper 11.1.2.3.0
I read a lot of information about this but still I am missing something. I am trying to set the value of a bind variable through Groovy expression in my VO. I want this Bind variable
to have the value from an attribute from another VO. I tried ''adf.object.MyAppModuleImpl.findViewObject('Users1').currentRow.Iduser''
I am getting "oracle.jbo.expr.JISyntaxError: Variable MyAppModuleImpl not recognized". I tried with 'MyAppModule' only but the result is the same.
Can anyone help please?
Thanks

How to access attributes of an instance?

For example, I declared an instance of a CustomNode class "workspaceRow".
     Group{
         translateX: 50
         translateY: bind (wsY * -1) + (i*25);
         content:[
                 workspaceRow{
                      lineNumber: i.toString();
                    myColor: theColor;
                    onMouseEntered: function( e: MouseEvent ): Void {
                        selectedRow = i.toString();
     }How do I access lineNumber? I'm trying to use it for the onMouseEntered function inside the workspaceRow (as seen above), but Eclipse says it cannot find lineNumber, because it's looking for it at the top of the hierarchy (as in, looking for lineNumber declaration on my main *.fx file, instead of inside the instance). It's because I need to be able to store some data inside, and retrieve it later on.

For that lineNumber thing, sorry about that. I was trying to access it in the onMouseEntered function, but decided to use var "i" instead, since it was what I used to generate a loop, and I use that same variable for lineNumber, but I know it'll give me problems later on.
Yeah, forgot about capitalized class names, and yes, WorkspaceRow is a class extending CustomNode.
Thanks a lot, your way worked. I am just wondering though, why doesn't JavaFX want to put the declaration and instantiation of the node inside Group{}? When I move those code blocks inside, Eclipse highlights the line "Group{" and says "unexpected type required: variable found : value".
If I proceed with initializing the instance right on the declaration inside Group{}, it says "This is the type of cyclic reference to workspaceRowNow that prevents type inference.". As in like this:
          var workspaceRowNode = WorkspaceRow{
                 lineNumber: i.toString();
               myColor: theColor;
               onMouseEntered: function( e: MouseEvent ): Void {
                   selectedRow = i.toString();
                   print(workspaceRowNode.lineNumber);
          }Can anyone explain what that means?

How to access Business object type attribute from a method/function modul ?

Hello,
i have created a business object type object along with attributes and methods. Now inside the method i want to access the attributes. inside the method i am writing:
data a type XXX.
a = me->attribute
this is creating a compilation error.
Now the method is defined as a function module in some package, so can anyone inform me how to access object attributes from the function module ?
pointes are awarded
Regards

Hello,
thanks for your answer, but this too did not work, "=>" is for static attributes and the attributes i have are not static. Moreover, i tried it but it gave the same error :
the abap error was when i was checking the code is :
the type me=>documenttype is unknown
as you know in SWO1 i created an object and when i create a method you link it to a function module and this is where you have the implementation of the method, so from this method how can i access the attributes on the main object that i created in SWO1
regards

How to access the attributes from a method

Hi,
Thanks to all who replied to my previous thread. Please let me know how to access the attributes in method of component controller in the view.

wd_comp_controller->method_component( ).
????? how to access the data of the method_component?
endmethod.
Kindly help me out in the syntax.

Mahathi

Hi mahathi
You should define the parameters in the header, not in the body of the method:
You can define it as importing, exporting, changing or returning, as you need. For example, in SE80
Parameter             Cl.declar.          RefTo        Opt        Type ref
node1                    importing            X                          if_wd_context_node
itab                       exporting                                        mara
method_component().
" code here...
endmethod.
and when you have to call the method,
wd_comp_controller->method_component(
                EXPORTING     node1 = nodelocal   " not importing!!!
                IMPORTING      itab   = itablocal      " not exporting!!!
i think that it's this what you want, don't i?

How come property attribute of jsp:getProperty knows which method to call

Hello friends,
I could not understand How come property attribute of <jsp:getProperty knows which method to call
<jsp:useBean id="test" class="BeanTest.testing" scope="page" />
<jsp:getProperty name="test" property="name" />
there is no method "name" in testing.class file
if u see the existing examples "date" given in TOMCAT , it is using many <jsp:getProperty tag, but the property name is not equal to the method method name in the Bean file
thanks,

First do you know what a
bean property sheet is?
If not say so.
Second, to your question
The Java Runtime Environment (JRE) uses introspection to identify the appropriate get() or set() methods of that bean. What is introspection?
Introspection is a process that allows the class to expose its accessable variables and methods and allows other classes to see what they can do with that class when requested. Eg:
public class MyBean{
private String someValue = null;
public MyBean(){
someValue = "Some String Value";
//Introspection will reveal this method
public String getSomeValue(){
return someValue;
} and
<jsp:getProperty name="...." property="someValue" />
will call the getSomeValue() method

Is there a way using lab view objects to let an object that is contained within another object get access to its owner?

I've been playing with lvoop for 4 or 5 months now, and in general I like it very much, but I've repeatedly wanted to build classes that know something about who owns them and I can't figure out how to make this happen.
The simple example I've been thinking about is imagine having a person class which contains a car class. Now say that I get an instance of a car class and I want to ask it who its owner is. In C++, I'd do this by giving the car class a pointer to the person class it belongs to. (Of course you have to worry about car objects that don't belong to anyone in which case the pointer has to point to NULL.)
I've tried copying this idea by giving the car class a data value reference to a person class, but when I dereference the reference using an in place loop and call a method on it I get data from the moment the reference was made and not the current data of the person class.
I realize this is sorta breaking data flow so maybe it's not possible on purpose?

Yes, LVOOP uses value based references, and when you split the wire to write the owner you created a data copy. The function you're after requires you do use a DVR for all class functions in which case you'll get reference based OOP, which is more familiar coming from text based OOP.
It just so happens that G# uses that approach, take a look at it.
