Thank you,
Although not entirely right, but you sure put me in the right direction, if anybody wants to know the (best) solution:
<jsp:scriptlet>
<![CDATA[
for (int i = 0; i < 5; i++) {
out.print(i);
]]>

Custom for loop tag

Hi all,
I am trying to implement a custom "for loop tag". But it seems to me that there is a type conversion problem. I've tried many ways to fixed it but I still cannot get it to work. I've dug through my books, searched the internet and this forum but I can't found anythig useful. I am really lost now! Can anyone help me with this? Many many many thanks!!

I took the custom for-loop one step further and now it can be nested with in other for-loop.
Hope this is the last time I have to reinvent the wheel. Now I REALLY apprecate JSTL!!

How to return multiple tags (based on different checks) in a for loop?

Hi,
I'm trying to return multiple elements, based on different checks that are done in the XQuery, within a for loop. But I'm getting syntax errors at any attempt to do this.
This is the structure of what I'm trying to do:
          <ActionList>
     <ACtion>
let $total := count(...)
for $x in (1 to $total)
     let $lineItems := $someVariable/*:Items/*:Item[$x]
     return
          if(...)
                    <Qty1>{...}</Qty1>
                         else     ""
                    if(...)
                    <Qty2>{...}</Qty2>
                         else ""
               {                                       if(...)
          <Qty3>{...}</Qty3>
                         else ""
          <LinesList>
                         let $totalcount(...)
                         for $y in (1 to $totalcount(...)
                              let $DTL := $someVariable*:DTL[$y]
                         return
                         <Line>
                              <Carrier>{...}</Carrier>
                              <Path>{...}</Path>

                                   else
                              }</CA>
                              <RE>{
                                   if(...)
                                        data($someVariable*:CA[@XX="RG"])
                                   else
                              }</RE>

                                                                 </Time>
                              </Line>
                    </LinesList>
                                             </ACtion>
                                             </ActionList>
I'm not able to return elements without having their father being returned as well, I just want to iterate over those fields and, based on that verification, decide whether they should be returned or not.
Can someone please advise?

An example anyway...

Calling a CAF program via web service generates QName cannot be null error, but only for 1/5 of the same call in a parallel for loop.

Surely if it was the service group unassign then reassign issue then none of the calls would have worked?

Hi David,
While a random error is still an error it will be difficult for support to find a problem for an error which is not reproducible. It is always a faster resolution if you can determine how to provoke the error and provide those details. If we can reproduce an error on internal systems then we can fix the problem quickly and without having to access your system.
regards, Nick

For loop in jstl

Hi i'm wondering what is the format of a for loop in jstl.
for example:
my for loop:
for(int i = 0; i< stringArray.Length(); i++){
i++;
thanks

<c:forEach var="i" items="stringArray">
${i}
</c:forEach>Note: stringArray should be a variable in scope, and not a scriptlet variables.

For loop in Korn Shell

Hi,
I want to write a C-Style for loop so that i can increment a variable using the loop.
for ex : for (( i=0 ; i < 10 ; i++ )) ; do echo $i ; done
The above mentioned code is not working for korn shell.
How to write a c-style for loop in korn shell?
Thanks
Sandeep

For loop in JSF View Pages

Hi ALL,
How can I work with iteration operation in JSF View Class as JSP scriptlets won't work in it
thanks
Sudhakar

Hi Sudhakar,
Thank you for explaining your requirement so clearly.
The task you are trying to achieve is not possible in the jsp source. The reason being that Creator has a page backing bean where the component declarations are done. Hence adding components via the jsp source would not work as the page backing bean is essential for the working of the application.
The solution for your problem would be something like this:
Create an integer property named counter in your session bean and initialise it to 0.
Add a gridpanel to your page.
In your page backing bean (Page1.java) constructor add the following code
for(int i=0; i<array.length;i++){
SessionBean1 sb = getSessionBean1();
int ctr = sb.getCounter();
UIComponent parent = gridPanel1;
HtmlSelectBooleanCheckbox chkBx = new HtmlSelectBooleanCheckbox();
chkBx.setId("checkBox" + ctr);
parent.getChildren().add(chkBx);
sb.setCounter(ctr+1);
The above code just uses one for loop. You could extend it to mak use of nested loops.
I hope this helps
Cheers

Geting ORA 936 -while building dynamic query in for loop.

HI,
I hav written a SP and its compiled and giving me the results for the data I am quering but giving ORA936 - missing expressin and giving ORA 6512 at 2 lines. Please help me me out where I am going wrong.

Created above SP and its compiled. When I try to execute the SP with below code I am getting--
DECLARE

V_t(1) := 10;
V_t(2) := 20;
Test(v_t,’25-APR-2012’,’30-APR-2012’,’Y’);
END;
The SP is building correct dynamic querry and its getting executed for id = 10 and 20, giving the correct results but though I defined only 2 ids while executing and written FOR lOOP upto ID.COUNT its building query for third time and that time its not getting id, so for the third time the last part of where clause is built like
SELECT.....
WHERE....
AND id = (its taking blank here)
GROUP BY ...;
and thus its giving me ORA 936 missing expression and ORA 06152 at line of RECORD TYPE declaration and line of OPEN rc for fullstr;
ERROR at line 1
ORA 00936 misssing expresiion
ORA 006152 at line 9
ORA 006512 at line 87
I hav put DBMS_OUTPUT statements @ every build of dynamic wuery and its correct. here I have not copid the code I hav typed hereso not wriiten DBMS_OUTPUT.
I tried lot of ways redefining Andstr := ‘’;
Whstr :=’’; after for endloop but its giving the same error. is this because I am using varray? If am providing 2 ids in anonymous block then how its building query for third blank ID value.
Please help me out here..
Thanks a lot..

Then you should have posted the one that compiles and gives you results.
The code you posted will not compile without errors. Edit your original post and provide the corrected code.
When you do please add \ tags on the line before and after the code to preserve formatting. See the FAQ for details.

Having errors in basic for loop

Folks
I am tring to write SQL script that implements a block that contains a for-loop which increments a counter from 1 to 10 and inserts the counter value into the results field of the LOOPING table that i have created. i want to insert a null val in place of the counter if the counter value is equal to either 6 or 8.
Below are my work
Table creation
CREATE TABLE LOOPING (Result VARCHAR2(60));
I am expecting a output like this
Result
1
2
3
4
5
NULL
7
Null
9
10
My SCRIPT
BEGIN
FOR COUNTER IN 1..10
IF ((COUNTER = 6 ) AND (COUNTER = 8 ))
THEN
INSERT INTO MESSAGES
VALUES(NULL);
ELSE
INSERT INTO MESSAGES
VALUES(COUNTER);
END LOOP;
END;
I am getting errors. I am a beginner . Please help me out .
can you point out my errors and explain
And finaly please tell me how to correct it .
Thanks
Guna

1) When you get an error, it's always helpful to post the details of that error (the error number and the line number). That makes it far easier for us to help you.
2) Thank you for posting your code and table definition. That definitely helps! In the future, you'll want to use the \ tag (6 characters, all lower case) before and after any code fragments to preserve the white space & indentation. That makes your code far easier to read.
3) Your code fails to compile because
- you are missing the LOOP keyword between lines 2 and 3
- you are missing the END IF at the end of your IF statement
- you are referring to a table named MESSAGES while your CREATE TABLE statement refers to a table named LOOPING
If you correct those three errors, your code will compile
[code]

[/code]
4) However, now that the code compiles, you'll have a problem that it does not meet the requirements. It will never insert a NULL value because your IF condition is incorrect. Since this looks like a homework problem, however, I don't want to completely give it away-- I've probably done more than I should have already.

How convert java FOR loop into taglib directive

hi all,
I have following code in my Jsp. It is working but, we dont want to use java FOR loop anymore. Instead use corresponding taglib directive.
How can i convert this Java FOR loop into taglib implementation of FOR loop ?
               <%
               for(int i=0;i< arrMemberBenefit.length;i++)     {
                    pageContext.setAttribute("arrMemberBenefiti", arrMemberBenefit);
System.out.println("PCPNAME: " + arrMemberBenefit[0].getPcpName());
%>
                    <tr class="rowOdd">
                         <td headers="t1h1" class="first"><c:out value="${arrMemberBenefiti.member.firstName}${space}${arrMemberBenefiti.member.lastName}" /></td>
                         <td headers="t1h2" class="last"><c:out value="${arrMemberBenefiti.pcpName}" /></td>
                    </tr>
<%}
%>
pl any help highly apprecialted
pp

Using the JSTL forEach tag:
I have used your variable name for arrMemberBenefiti
myself I would probably call it something like memberBenefit
You may need to put the array into an attribute to begin with
// just in case
<% pageContext.setAttribute("arrMemberBenefit", arrMemberBenefit); %>
// and the actual JSTL loop
<c:forEach var="arrMemberBenefiti" items="${arrMemberBenefit}">
<tr class="rowOdd">
    <td headers="t1h1" class="first"><c:out value="${arrMemberBenefiti.member.firstName}${space}${arrMemberBenefiti.member. lastName}" /></td>
    <td headers="t1h2" class="last"><c:out value="${arrMemberBenefiti.pcpName}" /></td>
</tr>
</c:forEach>Cheers,

Delayed Movement For Loop

I know this question has probably been asked and answered before, but after searching/reading in the forums, I'm still confused.
So I would like my VI to effectively move a stage a given distance with incremental sizes with pauses of between each step.
Effectively: "Go To" _____ With X step size: causes the VI to: move, pause, move pause...etc until the stage has reached the end.
To accomplish this I set up a for loop inside a case structure, and took the "Go To" / by Step Size to get the number of iterations the loop aught to run (labview apparently rounds the double result to the integer form), and then I send the "Step Size" to the MoveAbs VI.
I am not sure if my logic is terribly off, but when I perform the command, the stage at least moves, but not to the correct location.When I inserted probes, they list the correct values being sent to the subvi's etc...
Does anyone have an idea why this would not work? Any better ideas to institute this type of motion?
Thanks

Hey Tim,
I've got another question for you--I've been working on the program and I think I finally understand the basic outline. I've been trying to add other subvi's to increase functionality and I came across a problem:
The error list says that the selector values of the case structure are not unique--which is true of the program I am sending you. So naturally I deleted the extra "VI INI" which was tagged onto the default case. However doing so caused my program to crash--or more accurately cycle in an infinite loop. The program initializes over and over again. The "INI VI" sends another "INI VI" to the array and gets stuck.
I am not quite sure what is wrong, because when I looked at the original program you had sent to me, and earlier versions I had edited, I noticed that they have the same code within the "INI VI" case...in addition, now when I open previous programs--that were functioning perfectly well before--I get the same error message complaining about "not unique selector values". I honestly don't recall ever adding "INI VI" to the default case...
I am attaching the program and was wondering your thoughts, especially given the retrospective error...
Let me know if I was unclear in explaining the problem etc...and thanks again for your help. Others' input welcomed too!

Iterating through every other (or specified number) of element in an array using a for loop

I am trying to go through an array but instead of autoindexing I want to skip every other element or maybe a number of elements that will be specified for the user.
Basic functionality that I want to acheive is the following in C code.
int temp_var = 10;
int i=0;
for(i=0; i<=1000; i=i+temp_var)
I am very new to LabVIEW and I did not know how to use internal variables.
Can this be acheived using shift registers?
I am attaching the code I currently have for this. Let me know what you think.
Thanks guys.
Solved!

I have been asking for a new For Loop style that would allow us to specify start, stop, and step conditions, but it seems that many people are just not for this idea. Don't know why?
See here.
I wouldn't say there aren't many people for it. The idea you linked to was one of a half dozen of basically duplicate ideas, including another one of your own.
These two ideas have a fairly large number of kudoes showing people want the idea.

For loop stops iterating at first page

I have a loop that applies a paragraph style but it stops iterating at the first page of the document.
I need it to apply the style to the entire document...can't figure out why this isn't working.
Here is my script:
var myDocument = app.activeDocument;
var myParagraphStyle = myDocument.paragraphStyles.item("Paragraph Style");
myDocument.pages.item(0).textFrames.item(0).paragraphs.item(0).appliedParagraphStyle = myParagraphStyle;
var paragraphs = myDocument.pages.item(0).textFrames.item(0).paragraphs
for( i = 0; i < paragraphs.length; i++)
var paragraph = paragraphs.item(i)
paragraph.applyParagraphStyle(myParagraphStyle, true);
Thank you

myDocument.pages.item(0).textFrames.item(0).paragraphs.item(0).applied ParagraphStyle = myParagraphStyle;
Why do you have this line, when you iterate through the paragraphs later? (BTW: between "applied" and "ParagraphStyle" is a space)
But I think the problem is that you forgot two semicolon here:
var paragraphs = myDocument.pages.item(0).textFrames.item(0).paragraphs
(BTW: you should also call it "var myParagraphs ..." or something like that.)
and here:
var paragraph = paragraphs.item(i)
