Problem passing value from List Item to List Item

OK I will try to explain what I am trying to do. I have a Form that List Item at the top and they cascade from left to right. When I get to the BPOST_TAG I choose the Bpost then move to EPOST_TAG to choose the Epost. The EPOST_TAG should show all the Epost that go with Bpost you already chose, but it only showing 1 or 2. Below is the example of how should work!
SYSTEM     COUNTY     ROUTE   BPOST_TAG      EBPOST_TAG
1 77 80 025 030
------- The Return Values Should be as below-------------------------------------------------
Sy Co Route Dir Bpost Epost Miles Descrption
1 77 80 1 025 026 ? ?
1 77 80 1 026 027 ? ?
1 77 80 1 027 028 ? ?
1 77 80 1 028 029 ? ?
1 77 80 1 029 030 ? ?
1 77 80 2 025 026 ? ?
1 77 80 2 026 027 ? ?
1 77 80 2 027 028 ? ?
1 77 80 2 028 029 ? ?
1 77 80 2 029 030 ? ?
The top 5 List Items are based on the first Data Block (PMISCURR) and the bottom 8 columns are based on the second Data Block (PMISCURR1).
I have PRE-QUERY on the first Data Block (PMISCURR), below is code for the PRE-QUERY.
DECLARE
Wh_clause VARCHAR2(200);
BEGIN
IF :PMISCURR.SYSTEM is not null then
     Wh_clause := 'SYSTEM = '||:PMISCURR.SYSTEM;
END IF;
IF :PMISCURR.COUNTY is not null then
     Wh_clause := WH_CLAUSE ||'AND COUNTY = '||:PMISCURR.COUNTY;
END IF;
IF :PMISCURR.ROUTE is not null then
     Wh_clause := WH_CLAUSE ||'AND ROUTE = '||:PMISCURR.ROUTE;
END IF;
IF :PMISCURR.BPOST_TAG is not null then
     Wh_clause := WH_CLAUSE ||'AND BPOST_TAG = '||:PMISCURR.BPOST_TAG;
END IF;
IF :PMISCURR.EPOST_TAG is not null then
     Wh_clause := WH_CLAUSE ||'AND EPOST_TAG = '||:PMISCURR.EPOST_TAG;
END IF;
END;
OK It's just not my day I can't even get this line-up! :)

Hello,
Simply get the current item value in a When-List-Changed trigger:
current_value := :block.listitem ;Francois

Hi,
Coul'd You help me?
I have a test form. I open new JavaScript window from this form. I generate list of authors in this window by the procedure show_list. I want to pass value from JavaScript window back to test form, but
the command "window.opener.document.forms[idx_form].elements[idx_fld].value = val;"
don't pass value to test form. Where is mistake?

Java Thread - difficulty while passing value from parent to child thread

Hi All,
I am calling a java program from a unix script .
My oblectives are
1)to pass value from scripts to main java class
2)main class should create a child thread and pass data to child and should return control back to script
3)child thread should run independtly of parent
The calling unix script is part of process and hence should return control back to its calling script immediately.
Findings
1)Without passing data thru setter getter /constructor method to child thread my objectives are met
2)When I pass the data from parent thread to child thread calling unix scripts wait till child thread finishesh its working
call.scr
java Main <list of Arguments>
Main.java
public class Main
             public static void main(String args[]) throws Exception
             String data2="Z";
             String data1=null;
             for(int i=0;i<args.length;i++)
                  data2=data2+","+args;
data1=data2;
Child cu=new Child();
cu.setData(data1);
data2=null;
data1=null;
cu.start();
Child.javaclass Child extends Thread
public String data;
void setData(String data)
this.data=data;
public void run()
----------> processing on data
I think due to passing of data from parent thread to child thread (Inter thread data communication/Inter process communication)
the threads are not working as desired.
Plz anybody can suggest something.....
Thanx.

aschin,
You seem to be confusing Java Threads with Operating System Processes.
If you want you're java program to run in the unix background then you'll need to run it in the unix background. Java (being o/s agnostistic) doesn't provide process manipulation functionality (which would include the ability to throw itself into the background, as a C program can) in the standard API, and it's hard to imagine any third party producing anything as low level as a process controler... so yeah, just start the java program in the background... and you'll need to workout some interprocess communication protocol... named pipes have worked well for me in the past, as they doesn't suffer from the quit same performance issues as real disk files.
Good luck. Keith.

Script fails when passing values from pl/sql to unix variable

Script fails when passing values from pl/sql to unix variable
Dear All,
I am Automating STATSPACK reporting by modifying the sprepins.sql script.
Using DBMS_JOB I take the snap of the database and at the end of the day the cron job creates the statspack report and emails it to me.
I am storing the snapshot ids in the database and when running the report picking up the recent ids(begin snap and end snap).
From the sprepins.sql script
variable bid number;
variable eid number;
begin
select begin_snap into :bid from db_snap;
select end_snap into :eid from db_snap;
end;

Passing values from main report to sub-reports

- How do we pass values from main report to sub-report?

Look at this link which shows how to pass values from a subreport to a main report.
http://www.datamanagementgroup.com/resources/trainerstalk/trainerstalk_howto_share_subreport_data_with_main_report.asp
You can use the same method to pass values from main report to a subreport.
1) Create a formula @mainFormula in the main report, as given in item 1 of link.
2) Place this formulla in a suppressed report footer section above the target subreport.
3) In the subreport, create a formula @subFormula that declares the same variable name, as given in item 3 of link.
4) Place @subFormula column in the subreport where you want to display it.

OnSubmit function Error in passing values from WDA Adobe Form to Ztable

Friends,
I am trying to pass values from Adobe Interactive Form to ztable.
I am using WDA to display the form. I have created the form context with attributes that are bound to the form fields using the Adobe Livecycle Designer.
Once the user presses the Submit button, the data is passed to the ztable. In the onSubmit function assigned to the Submit button, I am using the "Read Context" feature of WD Code Wizard to read the values of the attributes
I am able to read and populate the ztable with values of the first 3 attributes. But am unable to read the value of 4th attribute using the "Read Context" feature of WD Code Wizard. All 4 attributes are of string type.
I am not sure if this is a buffer size problem or is there a limitation that only 3 attributes can be read per Adobe form / onSubmit function.
Please let me know what is missing.
Thanks and Regards.

JSF2 : Problem passing values with f:setPropertyActionListener

Hi,
I'm a JSF newbie, and I'm in front of a weird problem on a JSF2 / Glassfish3 project. I'm working on GlassFish Server Open Source Edition 3.1 (build 43) with Mojarra 2.1.0 (FCS 2.1.0-b11).
I'm using a commandLink to pass values from a page to a backing bean. This example works (here is only the relevant code) :
user.xhtml :

|#]So I wonder : what makes the first example work, that fails in this one ? Where does this 'null' value come from ? I tested every value (project, author, author id), everything is correct. But for some reason, the projectController.project.author.id is not passed to the userController.userId.
If I try to replace
<f:setPropertyActionListener value="#{projectController.project.author.id}" target="#{userController.userId}" />by this (obviously incoherent but syntically correct)
<f:setPropertyActionListener value="#{projectController.project.id}" target="#{userController.userId}" />I don't get the IllegalArgumentException anymore, but the value is still not passed, and the value of userController.userId is never updated, and remains set to 0.
But if I hardcode a valid value :
<f:setPropertyActionListener value="1" target="#{userController.userId}" />It works...
I can't understand why a 'null' value appears from who knows why, given that the only value passed are of long type.
Can you help me ? It's getting frustrating, and I didn't find any help on Google so far...
Thanks!

Ok, I have a little more time now.
You ask how the value can be null when the property is a long. What is happening is that something in the chain is null, e.g. the author is not set on the project. (Although usually you get an exception with that kind of thing.) The EL resolver is actually not really part of JSF, it is a separate library. Furthermore it is weakly typed so it doesn't know what type of thing projectController.project.author.id is until it evaluates it. If something is null along the way, there is no way for it to know whether the end result should have been a long, a Long, a String or anything else.
You asked how to pass values without setPropertyActionListener. It is certainly possible. In fact, I would not be surprised if my entire application did not use setPropertyActionListener. Let's start with the first case. In that situation you were using a dataTable. The customary thing to do is to bind the dataTable to a UIData property in a managed bean. Then, in your action method, you can invoke UIData.getRowData() and get the object instance associated with the row in the table that was activated by the user.
In your second example it is a little difficult to appreciate everything going on without more context but I'll just guess at what I don't know. I'm going to assume you have a simple page here. On the request that generates this page, projectController.project.author.id is known. I imagine the problem is that this is in request scope, causing projectController.project.author.id to be forgotten on the next request. The simplest solution is to store the project somewhere in session scope. I would recommend against putting the Controller classes themselves in the session scope. Instead create a set of beans for session scope and inject them into the Controller classes.
There are many other ways to skin the same cat. Many people object to over-using session scope. So you could store something small like just the id in the session. Or you could pass the id using h:inputHidden. Or you could use Tomahawk's s:saveState.

Passing values from a FORM to another FORM

Hi,
I have to pass values from FORM "A" to FORM "B". What is the best way to do this?\
Can I use a GLOBAL variable?
Thanks,
Marc.

I think he meant the global namespace.
You set a :global_your_name_here to a value and that value is available in your entire application. See the help file section on the global namespace for more information.
Forms parameters are parameters that you form picks up from the outside when it starts. The calling entity must supply them in the URL or they will be set to null. You set them up in the object navigator in the Parameters node.

Passing values from javascript in pop up window to parent jsp

Hi
I am trying to pass values from a pop up window to the main window that popped this child window , with the idea to have the parent window refresh itself with value from pop up window.But the values are not going through.I do a request on the hidden variable but when the parent
jsp refreshes , the variable is still null...
The following is the code i have .
Parent jsp:a.jsp
<form name='summary'>
<input type=hidden name=customerid value="">
<input type="button" class="textButton" name="action" value="customerlist" onClick="javascript:openWin('b.jsp','800','350')">
<script>
function openWin(loc, w, h) {
var newWin = window.openloc,"HTML",'dependent=1,toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=1,resizable=1,width=' + w + ',height=' + h);
newWin.window.focus();
</SCRIPT>
<%
String optionVal = request.getParameter("customerid");%>
var user = "<%= optionVal%>";
</form>
child jsp- b.jsp (pop up window)
<script>
function closer(){
var val = document.formname.id.selected.value;
window.opener.document.summary.customerid.value = val;
window.opener.location.reload();
</script>
<form name = formname>
<input type="text" name="id" value = ''>
<input type="button" class="textButton" value="select"
onClick="closer();window.close();">
</form>
Any ideas on what i am missing
Thanks
Arn

Passing Value from Crystal Report (special function) to Business View parameter

Friends,
Í have a scenario where i need to pass value from Crystal Report to a Business view's parameter.
Eg : CurrentCEUsername (func in crystal report)-- gives login user which i should pass to parameter in a Business view (used in the same report).
Will be able to explain more if required.
Thanks in Advance,
Bharath

I guess you got the picture wrong. User_id is not a report_level parameter .
In Data Foundation, below query is used..
select Acc_Number, Account_Group,User_id from Accounts where user_id={?User_id}
where in {?User_id} is the BV parameter...
The Filter was a solution. But it takes long time to Query all the data from DB and then filter at BV level.
How do i pass the CurrentCEUsername to {?User_id}
Value should ve CurrentCEusername always. so that query will be
select Acc_Number, Account_Group,User_id from Accounts where user_id=CurrentCEusername
It will restrict the data pulled from DB to BV .. right?

Pass value from Java to Perl

Anyone knows how to pass value from Java to Perl program?

Did you write the perl program? Can you change it? Or are you trying to interface to something that already exists? This will limit your options, of course.
Anyway the first option is simple. The java program does this:
System.out.println("This is a line of input.");The perl program does this:
while(<>)and in that block, $_ is assigned to each line of input.
Then you can invoke both like this:
$ java MyJavaProgram | perl MyPerlProgram.pl
