FieldLoop within TabPanel: HowTo pass loop variable to form within a Tab

Dear all,
I have a Tabbed User Form which contains a FieldLoop that creates Tabs based on the FieldLoop loop-variable.
Each created Tab should include the same form which differs only by the value of the loop-variable.
So I have a list of all my SAP systems, and want to create per SAP system a SAP User form that handles
the specific SAP resource.
In general this works, but it seems that only the first element of my list of SAP systems is passed through
the underlying form.
Here's an extract of the code I've wrote:
===[ FILE : MY TABBED USER FORM . XML ]========================================================

<Field name='MANAGED_SAP_LIST'>
<Display class='Text'>
<Property name='title' value='MANAGED_SAP_LIST'/>
</Display>
<Default>
<List>
<String>SAP_XXX-AAA</String>
<String>SAP_XXX-BBB</String>
</List>
</Default>
</Field>


<Field name='MainTabs'>
     <Display class='TabPanel'/>
     
     <FieldLoop for='currentSAP' in='MANAGED_SAP_LIST'>
          
          <Field name='$(currentSAP)'>
          <Display class='EditForm'/>
          <FieldRef name='accountId'/>
               
<Field name='SAP_SYSTEM'>
<Display class='Text'>
<Property name='invisible' value='true' />
<Property name='title' value='SAP_SYSTEM'/>
</Display>
<Default>
<ref>currentSAP</ref>
</Default>
</Field>
               
          
<FormRef name='MY SAP User Form'/>
          
     </Field>
          
     </FieldLoop>
     
</Field>

===============================================================================================
===[ FILE : MY SAP USER FORM . XML ]===========================================================
<Field name="thisSAP">
<Display>
<Property name="title" value="Managed SAP SYSTEM" />
<Property name="readOnly" value="true" />
</Display>
<Expansion>
<ref>SAP_SYSTEM</ref>
</Expansion>
</Field>
===============================================================================================
So currently I got 2 new tabs (as I defined 2 SAP systems) but the field "thisSAP" allways displays the first element of my list (i.e. SAP_XXX-AAA)
Is there another way to pass a FieldLoop loop-variable to an underlying form ?
many thanks in advance
Best regards
Joerg

Sorry i figured it out.
I had other session variables i was referencing in my sql query and had to add an:
or :p11_other is null
to my SQL query for each of them.

What is the scope of implicit loop variables?

Hi,
I'm facing some strange error from the ABSL editor (syntax checker).
In ABSL the loop variables are implicit and don't have to be declared in the head section of the script.
My question now is simple: How is the scope/visibility of such loop variables specified ?
There's a complete code snippet below.
In line no.9, there's the first time use of implicit loop variable 'task_inst'.
Because of type inference, it will be typed as MasterDataWanneBe/Tasks (which is my own BO type).
In line no.20, I want to use the same variable name in a different loop, outside the parenthesis/scope of the first first use.
Now the ABSL syntax checker complains about incompatible types (see code snippet)
Thus the type inference should result in the, (lets say 'local') type Project/Task, which is the one I was querying for.
To me it looks like, that loop variables implicitly get a global scope (hopefully bound to this ABSL file only).
I would like to see the scope/visibility of loop variables restricted to the parenthesis.
In other words only inside the loop.
Hint
I heard (from little sparrows), that local variable scoping is not possible because of underlying
generated ABAP code. If so, than it would be helpful to print warnings, in case of types are compatible
but used in different scopes. Think about the unintended side effects.
import ABSL;
import AP.ProjectManagement.Global;
var query_tasks;
var query_tasks_param;
var query_tasks_result;
foreach (empl_inst in this.Employees) {
     foreach (task_inst in empl_inst.Tasks) {
         //   ^^^^^^^^^ first time use
          task_inst.Delete();
// ===========================================================================
query_tasks = Project.Task.QueryByResponsibleEmployee;
query_tasks_param = query_tasks.CreateSelectionParams();
query_tasks_result = query_tasks.Execute(query_tasks_param);
foreach (task_inst in query_tasks_result) {
      // ^^^^^^^^^ Error: 4
      // The foreach loop variable is already inferred to an incompatible type:
      // Node(MasterDataWanneBe/Tasks). Expected Node(Project/Task)

Yes, variable declarations in ByD Scripting Language indeed have (snippet) global visibility. In the FP 3.0 release the variables can be declared anywhere in the snippet (not only in the beginning, as with FP 2.6), however still not within code blocks, i.e. within curly braces ({}). Therefore variable name shadowing is still not supported and because of the global visibility of variables they cannot be reused for a different type, later in the same snippet. This is because of the statically typed nature of ByD Script, despite the type inference convenience.
Kind regards,

How do i pass a variable in flex

i've been looking all over google for how to pass a variable yet
i've come up empty handed
i have a C code and as3
i've never been able to get a C program to compile on my own, this is from a tutorial im trying to understand about raycasting
from what i can gather i think that the variables are passed threw this
#######raycaster.c##########
AS3_Val loop( void* self, AS3_Val args )
    AS3_ArrayValue(args,"IntType,IntType,IntType,IntType",&K_UP,&K_DOWN,&K_LEFT,&K_RIGHT);
    CastRay();
    int opos,j,i,jpos;
    for(j=0; j < resY; j++ ){
        jpos = resX*j;
        for(i=0; i < resX; i++ ){
            opos = (jpos+i);
            tBuffer[opos] = buffer[i][j];
        }//end of for
    }//end of for
    return 0;
}//end of loop
however not one of the values inside of AS3_ArrayValue is to be found on the Main.as
this is the only function that comunicates with the C code, but i could be wrong
####Main.as######
        private function enterFrame(event:Event):void {
            alcRCLib.loop(upKey,downKey,leftKey,rightKey);
            alchemyMemory.position=alcScreenBufferPointer;
            screenBitmapData.setPixels(screenBitmapData.rect,alchemyMemory);
the reason i want to do this, other than to know how, because that would be useful above all else, i've already written a as3 that comunicates with php
to get a array of images for a topdown game, and i wouldn't know how to load these variables to C from a HTTP request but if i can get flash to tell c what they are then every thing worked out
heres both codes in full

How to pass a variable from one class to another class?

Hi,
Is it possible to pass a variable from one class to another? For e.g., I need the value of int a for calculation purpose in method doB() but I get an error <identifier> expected. What does the error mean? I know, it's a very, very simple question but once I learn this, I promise to remember it forever. Thank you.
class A {
int a;
int doA() {
      a = a + 1;
      return a;
class B {
int b;
A r = new A();
r.a; // error: <identifier> expected. What does that mean ?
int doB() {
     int c = b/a; // error: operator / cannot be applied to a
}Thank you!

elaine_g wrote:
I am wondering why does (r.a) give an error outside the method? What's the reason it only works when used inside the (b/r.a) maths function? This is illegal syntax:
class B {
int b;
A r = new A();
r.a; //syntax error
}Why? Class definition restricts what you can define within a class to a few things:
class X {
    Y y = new Y(); //defining a field -- okay
    public X() { //defining a constructor -- okay
    void f() { //defining a method -- okay
}... and a few other things, but you can't just write "r.a" there. It also makes no sense -- that expression by itself just accesses a field and does nothing with it -- why bother?
This is also illegal syntax:
int doB() {
      A r = new A();
      r.a; // error: not a statement
}Again, all "r.a" does on its own is access a field and do nothing with it -- a "noop". Since it has no effect, writing this indicates confusion on the part of the coder, so it classified as a syntax error. There is no reason to write that.

How to pass a variable for a SQL query in OLEDB source?

Hi All,
I am new to SSIS and working on it past few days. Can anyone please help me getting through a scenario where I need to pass a variable in the SQL statement in OLEDB source connection. Please find below for the details.
eg:
1) I have a SQL table with the columns SerialNumber, Name, IsValid, FileName with multiple rows.
2) I have the file Name in a variable called Variable1.
3) I want to read the data from my SQL table filtering based on the FileName (Variable1) within a data flow task and pull that data to the destination table.
Question: In the data flow task, added source and destination DB connection with a script component in between to perform my validations. When trying to retrieve the data from source using the variable (i.e. SQL Query with variable), I am not able to add
the query as the SQL statement box is disabled. How to filter the data based on the variable in the source DB ?
Any help/suggestions would be of great help.
Thanks,
Sri

Just to add with Vaibhav comment .
SQL Command : SQL query either with SQL variable or any condition or simple Sql statement
Like ;
Select * from dimcustomer
SQL Command using Varible :
Sometimes we design our dynamic query in variable and directly use that variable name in oledb source.
If you Sql query needs a condition based on SSIS variable .
you can find a Example here :

How to pass a variable into a cfc?

prior to calling the cfinvoke, I have coding that determins a
variable "X"
I need to pass X into a cfc so it can complete the query held
there.
So I tried
<cfinvoke component="A"
method="AList"
returnvariable="AResults">
<cfinvokeargument name="x" value="#X#"
/></cfinvoke>
correct so far?
Now over on the cfc page is where I'm getting stuck
Inside my cffunction I'm adding <cfargument name="X" />
But how do I get the value in?

I don't quite understand your question. Can you rephrase?
But before all that, bear in mind that one doesn't pass a
variables into a
*CFC*, one passes it into a function within the CFC. And as
with all
functions, one passes values into the function by passing it
as an
argument. But - of course - the function has to be coded to
expect the
argument.
Your own sample code demonstrates this in action:
<cfinvokeargument name="abbrCode"
value="#companyAbbrCode#" />
(NB: lose the trailing slash: this is CFML, not XML).
So you know how to do that.
Hence me not quite understanding what you're actually asking.

Passing a variable from a movie clip to the main timeline

Hi,
I'm having trouble passing a variable from a movie clip in my
flash file to the main timeline.
I have a movieclip with the instance name IntroNav which
contains several buttons. Clicking a button sets the variable
"page" to a specific name, i.e. page = "home"
However, outside of the movie clip, on the main timeline I am
unable to call this variable, and "page" seems to have no value.
Can anyone tell me why this is and how to solve it?
Thanks

Umm, yes ... declare your variables correctly.
var page:String = new String(); //proper complete
var page:String; //strict typing
var page:String = "home"; //stirct typing with value
declaration
Do not declare the variable in your buttons, you would have
to do so in every button and be constantly resetting the value.
Declare it on the main timeline at the lowest level. You do not
need to use it as a _global, you just need to resolve your path
issues. You can 'set' the variable value from a button, without any
problem, but you have to call to the variable correctly.
You do not 'name' a variable as "_root.page" , the '_root'
refers to the lowest level of the SWF or the main timeline, as does
a call to ' _level0' (that's a zero). If the variable is declared
on the main timeline, and you're calling from the MC/button or
anywhere you can refer to the variable by calling to it by
the proper path of '_root.page'
To set the variable from any of your button/MC instances
call:
_root.page = "value"; OR _level0.page = "value";
But you must have the varibale declared on the main timeline,
and only once and the playhead should be stopped or it will reset
the value to the default upon looping.

How to pass a variable from HTML to Flash

I have built my flash ad banner in Flash 9 and now want the
HTML code to pass the url over to the flash movie that it should
jump to when clicked.
The info in the help file seems out of date for the latest
HTML template as it uses mainly JavaScript to get round IE's
dreadful embeding issue. So my problem is, how do I pass a variable
from the HTML to the actionScript specified int he Help file
(running on a full screen button) as shown below?
myButton_btn.onRelease = function() {
if (clickTAG.substr(0, 5) == "http:") {
getURL(clickTAG);
via the html code now used by Flash 9 which is like this:

<html lang="en">

How to pass a variable from HTML to Flash 9

I have built my flash ad banner in Flash 9 and now want the
HTML code to pass the url over to the flash movie that it should
jump to when clicked.
The info in the help file seems out of date for the latest
HTML template as it uses mainly JavaScript to get round IE's
dreadful embeding issue. So my problem is, how do I pass a variable
from the HTML to the actionScript specified int he Help file
(running on a full screen button) as shown below?
myButton_btn.onRelease = function() {
if (clickTAG.substr(0, 5) == "http:") {
getURL(clickTAG);
via the html code now used by Flash 9 which is like this:

<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html;
charset=iso-8859-1" />
<title>Advert_long</title>
<script language="javascript"> AC_FL_RunContent = 0;
</script>
<script language="javascript"> DetectFlashVer = 0;
</script>
<script src="AC_RunActiveContent.js"
language="javascript"></script>
<script language="JavaScript" type="text/javascript">

How can I pass a variable between JSP and Role Form

I need to pass a variable from (a copy of) applicationmodify.jsp to the IDM Role Form so that the variable is available within the Role Form at display. We've tried getAttribute and setAttribute modifying both the Role Form and the applicationmodify JSP and can get the form to the role form but not accessible but have had no other success. Has anyone had any success in doing this? Any suggestions would be appreciated.

if by _root level you mean you're loading something into
_level0 you can't won't be able to use the localconnection. the
sharedobject is your only option.

How to pass a variable more than one values?

How to pass a variable more than one values?

You can't.
During 1 session, 1 ODI variable can have only 1 value at a time.
If you need more than 1 value, you will have to do somethink like a loop inside your package, and refresh the variable value each time.

How to pass Temp variable value instead of Table name in From clause.

Hi,
I have an requirement to pass the Temperorary variable value instead of Table name in FROM Clause in SQL.
But I am strugglint to pass this variable value.
E.g., a Varchar2(5) := 'aa';
Select * from a;
Here I come to mention a - 'aa'. But the SQL looks for 'a' as Table. But its should look into 'aa' as Table name.
Kindly guide me.
Thanks.

SQL> declare
a     varchar2 (5) := 'emp';
v     varchar2 (100);
cur   sys_refcursor;
begin
open cur for 'Select ename from ' || a;
fetch cur into v;
while cur%found
loop
    dbms_output.put_line (v);
    fetch cur into v;
end loop;
close cur;
end;

Is it possible to pass a variable in FROM clause in SQL?

Hi Experts,
<i><b>loop at it_db_table.
select field1 from it_db_table-table_name into my_it.
endloop.</b></i>
I mean, Is it pass a variable value to FROM clause in SQL?
I got the info from SAP as,
<i><b>Works like variants 1-3, provided the source_text varialb contains the table name or a join expression as ABAP source text.
Examples
Output of a list of all customers:
DATA tabname(10).
DATA: BEGIN OF wa,
        id   TYPE scustom-id,
        name TYPE scustom-name,
      END OF wa.
tabname = 'SCUSTOM'.
SELECT id name INTO CORRESPONDING FIELDS OF wa FROM (tabname).
WRITE: / wa-id, wa-name.
ENDSELECT.</b></i>
thanq.

Here is a short sample of a dynamic select statement.
Enter your table name in the parameter on selection screen. Enter you where clause in the select-option on selection screen.
I used.....
MARA
MTART = 'HALB'
report zrich_0004 .
data: xwhere(30) type c.
data: iwhere(30) type c occurs 0.
data:itab(1000) type c occurs 0 with header line.
parameters: p_table(30) type c.
select-options: s_where for xwhere.
loop at s_where.
clear iwhere.
xwhere = s_where-low.
append xwhere to iwhere.
endloop.
select * up to 100 rows into table itab
          from (p_table)
                where (iwhere).
loop at itab.
write:/ itab.
endloop.

Passing Presentation Variables to Guided Navigation

I'm having trouble passing Presentation Variables (and Session Variables) to analyses called via a Guided Navigation link in 11.1.1.5.
1. Created a dashboard prompt to select from a list of months. The prompt populates a Presentation Variable called pMo.
2. Created an analysis that displays two columns: Month and '{pMo}'
3. That analysis has this filter: Month is equal to / is in {pMo}
4. Put the dashboard prompt and the analysis onto a dashboard page.
5. Put an Action Link onto the dashboard page, calling that same analysis in a new window.
6. View the dashboard page
7. Initial analysis displays an error, which is expected since pMo has no value.
8. Select a month, which populates pMo. Analysis displays properly. Month and pMo both show correctly.
9. Click the Action Link.
10. The new window shows the correct value of Month, but NOTHING in the pMo column.
This is not logical. If the correct value of Month is shown in the new window, that means that Month MUST have been filtered using pMo. But the pMo column shows blank.
I see the exact same behavior with Session Variables. The value of the variable is correctly used to filter the analysis, but that variable's value doesn't show up in the analysis column.
In fact, if I assign a default value for the variable, the Month column shows the "correct" (i.e. selected) value, but the column containing the formula for the variable shows the variable's default value, not the value that was obviously used by the filter.
The problem only occurs in the new window that appears with the Guided Navigation link. The original dashbord page shows correctly.
Here's the error when using a Session variable. Similar error when using Presentation variable.
Error getting drill information: SELECT "Channels"."Total Channel" saw_0, "Times"."Month" saw_1, VALUEOF(NQ_SESSION.Mo) saw_2 FROM "Retrospectives" WHERE "Times"."Month" = 'Mar-2005'

So, if NQ_SESSION.Mo has no value, how did the Filter know that Mar-2005 should be used? NQ_SESSION.Mo DOES have a value. Why won't the column display it?
By the way, in case you're wondering 'what's the big deal', it's this: I want to be able to type a Commission Percent into a text box, store it in a variable, and then use that variable in a calculation within a Guided Nav link. That's what I was originally testing. The description above is what I finally figured out is happening. The variable has a value that can be used as a filter condition, but that value is ignored when used in the columns of that filtered analysis.

Edited by: Mark T. on Jan 7, 2012 7:15 AMI don't have 11g so what I say may not apply to you at all. That being said, it appears that what you are describing is similar to how the Link or Image and Guided Nav. objects work in 10g. Bear with me for a sescond while I explain. In the Link or Image object, you can open a destination report in a new window, but PVs don't pass through. In the Guid. Nav. object, PVs pass through to the destination, but you don't have the option to open the report in a new window. The filtering works, which is why your destination report is properly filtered; it's just that the PV is not passed and therefor the pMo column is blank.
Since you said your destination report opens in a new window, it is acting like the Link or Image object in 10g. So try doing this:
1) Ensure that your dashboard prompt is set to "dashboard" scope. This being that the PVs with the same name will be set for all dashboard pages, once set in the parent page.
2) Create a new dashboard page and include the same prompt as in the parent page, and your destination report. Hide the prompt on this page.
3) Now in your Action Link of the parent report, instead of pointing to the report itself, point it to the dashboard page created in step 2).
My theory is this: With the dashboard prompt set to dashboard scope, the PV of the prompt in the destination page will be set as soon as you hit the "Go" button. This will allow the report in the destination page to be set by the same variable, even though the value is not passed on directly through the Action Link.
