Call Function From MXML Component

I am using MXML to create components that I use within my
application. I have one MXML file that contains a list with a
custom itemRenderer that is in another MXML file. I have an
actionscript file with a function that I want to call from the
itemRenderer.
If I call the function from my main application, everything
works fine. If I try to call it from one of the other MXML files, I
get a 1180 Call to a possibly undefined function error.
Is there a special way that I need to use to call the
function?
The main MXML file is in the root directory, the actionscript
file is in a folder called functions, and the MXML files are in a
folder called components.
Thank you for any help.

I was able to figure out my problem. It was just a simple
typo of including the wrong file in a Script tag. However, this
caused more issues and I ended up having to rewrite a large section
of code to get everything working.
Thank you for your help.

How I can call controller's functions from another component?

Hi again!
I make a few web Dynpro components, for example first for user-data processing, second - for project-data processing. In the controller of 1-st controller there is a function getUserById(). In the controller of 2-nd component I need such function. And I don't want to make a dublicate for this function in the controller of 2-nd component. Is there a way to call function in one component from another?

Hi,
     Yes, you can reuse the component. There are two basic types of component communication. 1. Intra Component communication 2.Inter Component communication.
1. Intra Component communication: The two components must be in same DC(project).
Procedure:Say there are C1,C2 components in a DC.
Open C2, Open interface controller, create a similar (_parameters and return type_) method to the method C2. Call C2's method in this Interface method.
Open C1, select and right click Used Web Dynpro Components -> Add Used Component. In the wizard, you can browse and select the C2 component,and enter a name to the usage. Then the usage of the interface <b>must </b>be added in properties required controllers of a view/component controller.
Now we can use the method that is available in the C1 interface controller.
You must define method before declaring usage
<b>2.Inter Component communication:</b> The two components are in different DCs
Open DC metadata of C2. Right click on Public part-> create new Public Part.Enter name-> Next -> Select entity type as Web Dynpro Component in wizard,in Select Entities select the component ,Finish.
A structure for public part is created.
Open C1, Open DC metadata of C1. Right click on Used Dcs-> AddUsed DC. Browse to C2's public part.
Select Finish.

Siva

How to Call Function from SAPSCRIPT

I want to Call a function from my SAPSCRIPT to get some data and print the same in the form , Can I get an example for this

Hi Nandan,
U cannot directly call function from SAPScript... For that u have to create one include in which u need to write the code. Using Perform... EndPerform u can call the same from SAPScript. See the below example
u need to write this code in SAPScript
PERFORM formname IN PROGRAM includename
USING &field1&
USING &field2&
CHANGING &field3&
ENDPERFORM
Here includename is your include type program.
u need to write this code in your include type program..
FORM formname TABLES in_par STRUCTURE itcsy
                        out_par STRUCTURE itcsy.
data : var1 like field1,
       var2 like field2,
       var3 like field3.
READ TABLE in_par WITH KEY 'field1'.
CHECK sy-subrc = 0.
var1 = in_par-value.
READ TABLE in_par WITH KEY 'field2'.
CHECK sy-subrc = 0.
var2 = in_par-value.
now u can call corresponding function using local VAR1 and VAR2. Here u can pass N no of USING parameters.
After processing on VAR3...
READ TABLE out_par WITH KEY 'field3'.
out_par-value = VAR3.
MODIFY out_par INDEX sy-tabix.
EndForm.
Here in_par and out_par are the structures which will be used to communicate with SAPScript. And this is the only way as per my view.
I m sure this code will work fine. Here i have used dummy variables that u need to change as per your requirement. If u have more queries write me back.
And yes if this works than dont forget to give the points.

Sagar

Call function from data base with clob input parameter.

Hello,
In this project I use Jdev 11g.
I call function from database.
create or replace function get_fa_list (
p_fa_id_list in clob

is
vCursor sys_refcursor;
begin
put_msg ('begin');
if p_fa_id_list is null then
put_msg ('CLOB is null!');
else
put_msg ('size CLOB: ' || dbms_lob.getlength (p_fa_id_list));
end if;
put_msg ('Save');
open vCursor for
select rownum as id, s.*
from (
select f.latitude, f.longitude, count (distinct f.res_id) as res_count, count (*) as fa_count, 16711680 as color, res_concat_distinct (f.res_id) as station_list

where f.ext_system = 'BI' and
f.ext_sys_id = l.column_value
group by f.latitude, f.longitude

end get_fa_list;
I use TopLink in ejb.
i use follow code for call function and get result.
public List<TmpResPoints> findAllPointsBI(String p_id){
UnitOfWork uow = getSessionFactory().acquireUnitOfWork();
uow.beginEarlyTransaction();
StoredFunctionCall call = new StoredFunctionCall();
call.setProcedureName("get_fa_list");
call.useUnnamedCursorOutputAsResultSet();
ClobDomain c = new ClobDomain(p_id);
//System.out.println(c.toString());
call.addNamedArgumentValue("p_fa_id_list", c);
ReadAllQuery query = new ReadAllQuery();
query.setReferenceClass(TmpResPoints.class);
query.setCall(call);
List<TmpResPoints> result = (List<TmpResPoints>)uow.executeQuery(query);
uow.commit();
uow.release();
return result;
But size parameter "p_fa_id_list" is 0. (geting from temp table in Data base). this code in function >>
if p_fa_id_list is null then
put_msg ('CLOB is null!');
else
put_msg ('size CLOB: ' || dbms_lob.getlength (p_fa_id_list));
end if;)
How I can call this function from dataBase and get result?
thx,
Demka.

What is the SQL generated?
The argument should just be the Clob value (a String) not the domain object.
Also try addNamedArgument, and then pass the named argument to the query.

Calling RFC from view/component controller

I've got a model node in the component controller's context which is mapped to a node in a view controller. Now, when binding the model's input node with an array and executing the RFC from within an event handler in the view controller, everything goes just fine.
Now, I want to put this functionality in the component controller, so I created a method there, copied the code and call it from the view controller's event handler. When the RFC is called, the input table always contains just 1 element, of which the fields are all initial.
Any thoughts on what might be going on here?

Hi friend,
I too faced the problem what you faced.
Near to it.
Ill explain you .
YOu have your model node.
1st you will map that to component controller And from there to view controller.
After that you will bind the elements in this node to some elements in your view after that .
For example
Model class name:-Lok_model.
In the DOINIT method:-
write this code.
Lok_model k = new Lok_model(); wdContext.nodeLok_model().bind(k);
Suppose you have a button in the onaction you write this code.
wdContext.nodeLok_model().currentLok_modelElement().modelObject().get_details();
Ill expalin you about this statement Lok_model() is the node in my view which is mapped from the model and by using that i am calling the method get_details() which is in my model class Lok_model.By this data will be automatically populated into the view elements which are being binded to the model attributes.
Hope this helps you,
Lokesh

Calling function from PL/SQL block

Hi,
A very simple question.
A have a function called "test1" in my database. It is there i double chekked.
I would like to call this function from a block:
DECLARE
BEGIN
TEST1(1202);
END;
This gives me an error.
Why is this?

Why is this?Hello
A very very basic thing to do when you get an error is to include details of it. That helps narrow it down from one of the 1000s of potential Oracle errors it could be.
Anyway, a function returns a value, and in PL/SQL you need to capture that otherwise you'll get "an error". Modify your code like so
DECLARE
l_Test1Val VARCHAR2(4000); --CHANGE THIS TO BE THE SAME AS THE RETURN TYPE FOR YOUR FUNCTION
BEGIN
l_Test1Val := TEST1(1202);
END;HTH

Calling Functions From Import Integration Script

I've got an import integration script that runs fine, however I also have several DataPump scripts that are used in FDM to change specific columns as they come in. I can take the code from the scripts and add to the Import Integration script, but I would rather just call those other functions from the VBScript. I don't see any docs on this, and I'm just wondering if anyone has done this or can describe how I can do it.
Is it possible? Since the standard import scripts reference the strField and the strRecord, can these functions be called from the import integration script?

strField and strRecord are arguments passed by the application to the import function. The represent the field as defined by the import format and the record that is being processed during the import.
Given that, I'm not sure how to answer your question.

Calling function from sql folder vs report

Hi,
A report based on a custom sql folder is taking a long time to run. One of the things that I noticed is that when I run the sql in plsql it takes a long time, but if I remove the row where I call a function, it runs pretty quickly.
In general, is there a difference between running a function from the sql custom folder and calling it from the report itself?
Thanks.
Leah

Hi Tamir,
I might check out the execution plans, but truthfully, understanding the plans and the meaning of the differences is not my strong point.
I thought that maybe there was some general rule that, for instance, it is better to keep functions out of the sql folder and use them in a condition in the report itself, or the opposite, or that maybe it makes no difference at all.
I appreciate the response.
Thanks.

What is the syntax for calling function from class file by jsp

does anyone here knows what is the syntax of how to call a function from java class file by javascript code or any way to call it?
and where should i put the calling function code? because the function is called depend on the user click.
for example
<%=pc.functionName(a,b)%>
for the variable a and b, how can i get the value from html textbox and put it in a and b...
urgent needed...
thx

Jsp's are executed before the Html forms are created and loaded. Dont try to use a java code function calling on a javascript click. You'll have to explicitly redirect it into a servlet where in you can call the function you want.
Well! another way could be using AJAX. That seems to be powerfull enough and it might also serve your purpose.
Hope this helps

Put SQL query in a function/ call function from region

How can I write a SQL query (like SELECT EMPNO, ENAME, JOB FROM EMP) as PL/SQL function, and then call this function from the PL/SQL Function Returning SQL Statement region?
Thanks, Tom

thanks jverd for your quick reply.
I know passing in a reference to an object will do the job if I want to change the value several parameters in one function call.
But I want to ask, is there any other ways?
the following code works.....
public class TestParameter {
     public static void main(String[] args) {
          Test2 t2 = new Test2();
          invokeChange(t2);
          System.out.println("x = " + t2.x + "\t y = " + t2.y);
     static void invokeChange(Test2 t2) {
          t2.x = 10;
          t2.y = 15;
class Test2 {
     int x;
     int y;
}

Getting session hang When calling Function from SQL query

Hi All,
I am using Oracle 8.1.7.4.0. I have a fucntion in a Package and I am calling it from the SQL query. When I am firing the query my oracle session is going to hang position and I am not able to any thing. I have to kill the session.
But this same thing is working fine in Oracle 9.i.
There are no out parameter and no DML, DDL and DCL statement in this fucntion.
Could you please get back me what is the problem on it.
Regards
SUN

Check why your session hangs.
Just a few ideas:
* Blocking locks?
* Endless loop?
* Performance (maybe it is just slow in orac8i and you have to wait a bit longer). Check the execution plans of the SQL statements in your function.
* Don't use a function, but direct SQL, it is faster in both versions.

Calling function from Backing Bean or JSP page

We are on Jdeveloper 10.1.3.3.0, ADF Faces, JSF Faces .., Currently there is a function call from Javascript event (onmouseover) in the JSP page. I want to call this function from a backing bean or JSP page, as I have to pass some values to this function.
For Ex., I have a function call like return submit('A','B','Test'); on the Javascript event (onmouseover) in jsp page. I want to remove this function from the javascript event and call from backing bean or jsp page to pass some values into the submit() function. I appreciate if anyone can give some example of how to call this function from backing bean or jsp page in the <SCRIPT> or <SCRIPTLET>
Thanks,
Ram

A use case would be helpful so that we can get a better idea of what you want to do.
As a general rule, there is no way to call a client side Javascript function from a backing bean, which is server side. However, there are ways to inject information from a backing bean into your Javascript call. For instance, I have an application that uses Google Maps API. It has an onload call to a Javascript function that builds the map and designates it's center point. The center point comes from a backing bean as latitude and longitude properties. So here is my body tag:
<afh:body onload="initialize(#{backing_searchResults.latitude},#{backing_searchResults.longitude},#{searchCriteria.distance})"
onunload="GUnload()">onload calls the Javascript function called initialize, and passes the latitude, longitude, and distance from the bean. Is the function really being called from my backing bean? No - the parameters are hard coded into the onload event code when the page is rendered. Does it do the job? Sure it does.
