Collapsible div containing nested loop

How would you recommend doing this. I have a query generating a loop of rows. and a sub query creating a loop or rows based on values from the first query loop. I want to contain the sub query loop of rows into a div, and use the first loops row as a trigger to drop down the sub. I.E.
loop1 start
+ category
select plus and get sub categories
loop2 start
sub1
sub2
sub3
loop2 end
loop1 end

Without knowing more than what you said it will depend. If you want to do this without a page refresh you will need to investigate into the JQuery, or similar, library and look at posting to forms on the fly so that the second query is run after the first.
The simpler solution is to reload the page. Either way the second query will have variables in the query so that it can properly execute. The below is a link to an example of using JQuery if you want the drop-downs to be updated automatically:

Building Tree hierarchy Using nested loops and class cl_gui_column_tree

Hello gurus,
I want to create a tree report using custom container and class cl_gui_column_tree. I have read and understood the standard demo report which SAP has provided i.e. SAPCOLUMN_TREE_CONTROL_DEMO. But in this report all the levels nodes are created as constants and hardcoded. I want to create hierarchy using nested loops. For this i took one example of a hierarchy of VBAK-VBELN->VBAP-POSNR Like One sales order has many line items and each line item can have number of line items in billing plan.
I have done some coding for it.
FORM build_tree USING node_table TYPE treev_ntab
                                       item_table TYPE zitem_table.              " i created the zitem_table table type of mtreeitm in SE11.
DATA: node TYPE treev_node,
             item TYPE mtreeitm.
node-node_key = root.
CLEAR node-relatkey.
CLEAR node-relatship.
node-hidden = ' '.
node-disabled = ' '.
CLEAR node-n_image.
CLEAR node-exp_image.
node-isfolder = 'X'.
node-expander = 'X'.
APPEND node TO node_table.
item-node_key = root.
item-item_name = colm1.
item-class = cl_gui_column_tree=>item_class_text.
item-text = 'Root'.
APPEND item TO item_table.
item-node_key = root.
item-item_name = colm2.
item-class = cl_gui_column_tree=>item_class_text.
item-text = 'Amount'.
APPEND item TO item_table.
LOOP AT it_vbeln INTO wa_vbeln.
    node-node_key = wa_vbeln-vbeln.
    node-relatkey = root.
    node-relatship = cl_gui_column_tree=>relat_last_child.
    node-hidden = ' '.
    node-disabled = ' '.
    CLEAR node-n_image.
    CLEAR node-exp_image.
    node-isfolder = 'X'.
    node-expander = 'X'.
    APPEND node TO node_table.
    item-node_key = wa_vbeln-vbeln.
    item-item_name = colm1.
    item-class = cl_gui_column_tree=>item_class_text.
    item-text = wa_vbeln-vbeln.
    APPEND item TO item_table.
    item-node_key = wa_vbeln-vbeln.
    item-item_name = colm2.
    item-class = cl_gui_column_tree=>item_class_text.
    item-text = wa_vbeln-netwr.
    APPEND item TO item_table.
    LOOP AT it_posnr INTO wa_posnr.
    node-node_key = wa_posnr-posnr.
    node-relatkey = wa_vbeln-vbeln.
    node-relatship = cl_gui_column_tree=>relat_last_child.
    node-hidden = ' '.
    node-disabled = ' '.
    CLEAR node-n_image.
    CLEAR node-exp_image.
    node-isfolder = ' '.
    node-expander = ' '.
    APPEND node TO node_table.
    item-node_key = wa_posnr-posnr.
    item-item_name = colm1.
    item-class = cl_gui_column_tree=>item_class_text.
    item-text = wa_posnr-posnr.
    APPEND item TO item_table.
    item-node_key = wa_posnr-posnr.
    item-item_name = colm2.
    item-class = cl_gui_column_tree=>item_class_text.
    item-text = wa_posnr-netpr.
    APPEND item TO item_table.
    ENDLOOP.
ENDLOOP.
ENDFORM.
Now this program compiles fine and runs till there is only one level. That is root->vbeln. But when i add one more loop of it_posnr it gives me runtime error of message type 'X'. The problem i found was uniqueness of item-item_name as all the sales order have posnr = 0010. What could be done? I tried giving item_name unique hierarchy level using counters just like stufe field in prps eg. 10.10.10, 10.10.20,10.20.10,10.20.20,20.10.10 etc.. etc.. but still i am getting runtime error when i add one more hierarchy using nested loop. Plz guide.

Hello all,
Thanks the issue is solved. The node key was not getting a unique identification as nodekey. I resolved the issue by generating unique identification for each level. Thanks all,

Creating nested loops

Hi!
I would like to list all Combinations of a list A and a list B (each containing 5 integers) in a third list C in order to get 25 combinations. I am intending to use nested loops so that on the first loop the second loop starts and then the result lets say list A + list B are listed in the list C. Is there any other way of doing this with Labview or I am on the right track?
Best Regards,
Hamid

You can use the polymorphic array math to accomplish this. Inside of a single for loop, index Array A and add that to the entire Array B in one shot. At this point, there are numerous ways to take the output. Probably the simpliest is to reshape the output 2D array into a 1D array. For better memory allocation, you can preinitialize a 1D array and replace elements in the for loop but in the end it accomplishes the same task. See attached example (LV7.1.1). Of course everything is dependant on what you are going to do with this, what operations, when and where the numbers come from.

Partition pruning, Nested loops

Hi,
I am having a problem with getting partition pruning in a query. I've managed to dumb down the problem to two tables and a minimal query (see below).
Basically, I have a partitioned table "Yearly Facts", and a helper table "Current Year" that always contain 1 row. The sole purpose of this one row is to tell what the curent year is, what the previous year was and what the next year will be. (In the real problem, there are non-standard timeperiods, so one cannot just calculate previous and next by adding/subtracting 1 as would be possible in this example).
The following query is executed the way I want.
It performs a scan on current_year, and then nested loop into the facts. And partition pruning was happening.
select sum(decode(a.year_key, b.curr_year, some_measure)) as curr_year_measure
from yearly_fact_t a
      ,current_year b
where a.year_key = b.curr_year;

Nested Loop and Driving Table.

In the documentation I read these (/B19306_01/server.102/b14211/optimops.htm#i82080).
The optimizer uses nested loop joins when joining small number of rows, with a good driving condition between the two tables. You drive from the outer loop to the inner loop, so the order of tables in the execution plan is important.
The outer loop is the driving row source. It produces a set of rows for driving the join condition. The row source can be a table accessed using an index scan or a full table scan. Also, the rows can be produced from any other operation. For example, the output from a nested loop join can be used as a row source for another nested loop join.>
I need some help to understand the bold line, i.e. so the order of tables in the execution plan is important.
There are various conflicting opinion about the driving table (some says smaller and some says larger table is good option) and unfortunately I did not understand any of those logic.
I read these threads/blogs also.
CBO (optimizer) nest-loop join question
http://hoopercharles.wordpress.com/2011/03/21/nested-loops-join-the-smaller-table-is-the-driving-table-the-larger-table-is-the-driving-table/
In practice, I have seen explain plan for select e.ename,d.dname
2 from emp e, dept d
3 where e.deptno=d.deptno; usages emp as driving table (I only understood part of Aman's logic that dept table access would be faster when there would be an index available over it and hence it is in the inner loop)
Whereas, SQL> explain plan for
2 select e.ename,d.dname
3 from emp e, dept d
4 where e.deptno=d.deptno
5 and e.deptno=20; usages dept as driving table.
I have use USE_NL_WITH_INDEX with LEADING hint to change it, but it is giving some adverse effect (sometimes with optimizer_mode ALL_ROWS it is ignoring the hint completely).
so the order of tables in the execution plan is important. How can I determine it ? I have read Tom's effective oracle by design but there is also no solution.

Not sure I quite understand the question.
Both threads contain lots of useful information about the broad considerations in play and debunking any myths.
I need some help to understand the bold line, i.e.
"so the order of tables in the execution plan is important"I read this as meaning just what it says, i.e. read the execution plan carefully and that
NESTED LOOP
A
Bis not the same as
NESTED LOOP
B
AA 10053 trace would normally be quite verbose about it's considerations as to join order.

Using collapsible divs with cfoutput

Hi there -
I haven't quite got started yet - I'm trying to avoid a bunch
of time-consuming experimentation and was hoping
someone here had already done something like this and could
point me in the right direction -
I'm attaching some code created by Dynamic Drive that creates
collapsible divs from hard-coded info (as in a
dynamic menu tree). What I'd like to do is figure out a way
to replace that hard-coded info with data dynamically
generated with a query, looping through as one does with a
table. I'm avoiding using the table because the number
of variables is so many, outputting them to table rows is
overwhelming for the viewer. I'm thinking collapsible divs
will do the trick nicely.
How would I go about using the attached code to loop through
the query and dynamically create divs? It doesn't
seem like it's a simple matter of creating a cfoutput using
this code with the necessary variables, like when you
use a query to generate rows in a table... From what I've
seen, it looks like maybe I'd have to convert to query to
xml (as per another collapsible div example I've seen). This
looks hairy to me! so I'm wondering if that's strictly
necessary. If this is the only way, I guess I just need
someone to tell me so and that's what I'll do. Any ideas?
Here's what I'm trying to create:
Output name of first teacher - a date - a second kind of date
**beginningoffirstcollapsiblediv**
Information about a workshop - more info - more info
Information about a workshop - more info - more info
**endoffirstcollapsiblediv**
Output name of second teacher - a date - a second kind of
date
**beginningofsecondcollapsiblediv**
Information about a workshop - more info - more info
Information about a workshop - more info - more info
Information about a workshop - more info - more info
Information about a workshop - more info - more info
**endofsecondcollapsiblediv**
Output name of third teacher - a date - a second kind of date
**beginningofthirdcollapsiblediv**
Information about a workshop - more info - more info
Information about a workshop - more info - more info
Information about a workshop - more info - more info
**endofthirdcollapsiblediv**
and so on... for as many staff as fit the query's parameters.

Okay - I'm feeling pretty dumb - I just discovered that there
is a Spry widget that does this sort of thing - boy, do things move
quickly!

hi sagar,
Pls go through the following explanations for understanding abt control level processing.
Control level processing is allowed within a LOOP over an internal table. This means that you can divide sequences of entries into groups based on the contents of certain fields.
Internal tables are divided into groups according to the sequence of the fields in the line structure. The first column defines the highest control level and so on. The control level hierarchy must be known when you create the internal table.
The control levels are formed by sorting the internal table in the sequence of its structure, that is, by the first field first, then by the second field, and so on. Tables in which the table key occurs at the start of the table are particularly suitable for control level processing.
The following diagram illustrates control level processing in a sorted table, where different field contents in the first three fields are indicated by different colors:
Each change of color in a column indicates a control level change in the corresponding hierarchy level. Within the processing block of a loop, you can use the control level statement AT to react to a control level change. This enables you to restrict statements to a certain set of lines. You can thus use the SUM statement to calculate totals from subsets of all lines.
The AT statement introduces a statement block that you end with the ENDAT statement.
AT <level>.
<statement block>
ENDAT.
You can react to the following control level changes:
<level>
Meaning
FIRST
First line of the internal table
LAST
Last line of the internal table
NEW <f>
Beginning of a group of lines with the same contents in the field <f> and in the fields left of <f>
END Of <f>
End of a group of lines with the same contents in the field <f> and in the fields left of <f>
You can use control level statements to react to control breaks in internal tables instead of programming them yourself with logical expressions. Within the loop, you must order the AT-ENDAT statement blocks according to the hierarchy of the control levels. If the internal table has the columns <f1>, <f 2>, ...., and if it is sorted by these columns, you must program the loop as follows:
LOOP AT <itab>.
AT FIRST. ... ENDAT.
    AT NEW <f1>. ...... ENDAT.
      AT NEW <f2 >. ...... ENDAT.
          <single line processing>
      AT END OF <f2>. ... ENDAT.
    AT END OF <f1>. ... ENDAT.
AT LAST. .... ENDAT.
ENDLOOP.
The innermost hierarchy level <single line processing> processes the table lines that do not correspond to a control level change. You do not have to use all control level statements. But you must place the used ones in the above sequence. You should not use control level statements in loops where the line selection is restricted by WHERE or FROM and TO. Neither should the table be modified during the loop.
If a control level field <fi> is not known until runtime, you can specify it dynamically as (<n i>) where <n i> contains the field of <f i>. If <n i> is empty at runtime, the criterion for changing the control level is ignored. You can restrict the search to partial fields by specifying offset and length.
If you are working with a work area <wa>, it does not contain the current line in the AT... ENDAT statement block. All character fields to the right of the current group key are filled with asterisks (*). All other fields to the right of the current group key contain their initial value.
Within an AT...ENDAT block, you can calculate the contents of the numeric fields of the corresponding control level using the SUM statement.
SUM.
You can only use this statement within a LOOP. If you use SUM in an AT - ENDAT block, the system calculates totals for the numeric fields of all lines in the current line group and writes them to the corresponding fields in the work area (see example in ). If you use the SUM statement outside an AT - ENDAT block (single entry processing), the system calculates totals for the numeric fields of all lines of the internal table in each loop pass and writes them to the corresponding fields of the work area. It therefore only makes sense to use the SUM statement in AT...ENDAT blocks.
If the table contains a nested table, you cannot use the SUM statement. Neither can you use it if you are using a field symbol instead of a work area in the LOOP statement.
Examples
DATA: BEGIN OF LINE,
         COL1 TYPE C,
         COL2 TYPE I,
         COL3 TYPE I,
      END OF LINE.
DATA ITAB LIKE HASHED TABLE OF LINE
          WITH UNIQUE KEY COL1 COL2.
LINE-COL1 = 'A'.
DO 3 TIMES.
LINE-COL2 = SY-INDEX.
LINE-COL3 = SY-INDEX ** 2.
INSERT LINE INTO TABLE ITAB.
ENDDO.
LINE-COL1 = 'B'.
DO 3 TIMES.
LINE-COL2 = 2 * SY-INDEX.
LINE-COL3 = ( 2 * SY-INDEX ) ** 2.
INSERT LINE INTO TABLE ITAB.
ENDDO.
SORT ITAB.
LOOP AT ITAB INTO LINE.
WRITE: / LINE-COL1, LINE-COL2, LINE-COL3.
AT END OF COL1.
    SUM.
    ULINE.
    WRITE: / LINE-COL1, LINE-COL2, LINE-COL3.
    SKIP.
ENDAT.
AT LAST.
    SUM.
    ULINE.
    WRITE: / LINE-COL1, LINE-COL2, LINE-COL3.
ENDAT.
ENDLOOP.
The output is:
A 1 1
A 2 4
A          3          9
A          6         14
B          2          4
B 4 16
B 6 36
B         12         56
        18         70
The program creates a hashed table ITAB, fills it with six lines, and sorts it. In the LOOP - ENDLOOP block, the work area LINE is output for each loop pass. The first field of the table key, COL1, is used for control level processing. The total for all numeric fields is always calculated when the contents of COL1 change and when the system is in the last loop pass.
DATA: BEGIN OF LINE,
        CARRID   TYPE SBOOK-CARRID,
        CONNID   TYPE SBOOK-CONNID,
        FLDATE   TYPE SBOOK-FLDATE,
        CUSTTYPE TYPE SBOOK-CUSTTYPE,
        CLASS    TYPE SBOOK-CLASS,
        BOOKID   TYPE SBOOK-BOOKID,
      END OF LINE.
DATA ITAB LIKE SORTED TABLE OF LINE WITH UNIQUE KEY TABLE LINE.
SELECT CARRID CONNID FLDATE CUSTTYPE CLASS BOOKID
       FROM SBOOK INTO CORRESPONDING FIELDS OF TABLE ITAB.
LOOP AT ITAB INTO LINE.
AT FIRST.
    WRITE / 'List of Bookings'.
    ULINE.
ENDAT.
    AT NEW CARRID.
      WRITE: / 'Carrid:', LINE-CARRID.
    ENDAT.
      AT NEW CONNID.
        WRITE: / 'Connid:', LINE-CONNID.
      ENDAT.
        AT NEW FLDATE.
          WRITE: / 'Fldate:', LINE-FLDATE.
        ENDAT.
          AT NEW CUSTTYPE.
            WRITE: / 'Custtype:', LINE-CUSTTYPE.
          ENDAT.
               WRITE: / LINE-BOOKID, LINE-CLASS.
            AT END OF CLASS.
              ULINE.
            ENDAT.
ENDLOOP.
In this example, the sorted internal table ITAB is filled with data from the database table SBOOK using the Open SQL statement SELECT. The sequence of the columns in the internal table defines the control level hierarchy. Since the table key is the entire line, the sort sequence and the control level hierarchy are the same. The sequence of the AT-ENDAT blocks within the LOOP and ENDLOOP statements is important.
The output is as follows:
List of Bookings
Carrid: AA
Connid: 0017
Fldate: 1998/11/22
Custtype: B
00063509 C
00063517 C
00063532 F
00063535 F
Custtype: P
00063653 C
00063654 C
00063668 F
00063670 F
Fldate: 1998/29/11
Custtype: B
00064120 C
00064121 C
and so on.

Collecting data from nested loops

I have ended up with a program having "case" loop at the top level and 3-4 nested "for" and "while" loops. Now from the inner most loop from each "case", I want to pull out the data, fromat it and then write it in a excel sheet. The problem is that I am not able to pull out the data. Everytime I try to do it, the dimension of array changes due to the nested loops. Is there a better way to do it?
Thanks,
Vivek

It is not possible for us to troubleshoot the code from an image that only show part of it.
From what I can see, a lot of things don't make much sense. Also please don't run wires backwards (such as the wires from the "How many channels" Control entering the big loop from the right.) This can make reading and debugging a diagram very difficult!
Let's look at the inner FOR loop on the right: It runs several times, generating 1D arrays each time.
Leaving this loop, they autoindex into 2d arrays, whitch you reshape into 1D arrays.
Leaving the next loop some are autoindexed into another 2D array, except for the top one, where you only retain the data from the last iteration. Is that really what you want?
Now we exit a case strucure, where apparently each case has it's own three outputs, so for each case, One set contains data, but the other two sets generate empty data. About 2/3 of all your data is zero, this is a lot of wasted memory!
Leaving the big FOR loop, nothing is indexed, meaning you only get sets of 1D and 2D arrays from the last iteration. If you would autoindex, you would get 2D and 3D arrays.
As you can see, this all make little sense unless we can see the code and some real data. Also, you have not implemented any of my suggestions from above. Why not?

SE30, Performance, nested loop

Hi,
I looked at SE30 and found something verny usefull for my actual report.
The nested reports and how to do it better.
In the Documentation is written:
The above parallel cursor algorithm assumes that ITAB2 contains only
entries also contained in ITAB1.
If this assumption does not hold, the parallel cursor algorithm
gets slightly more complicated, but its performance characteristics
remain the same.
I would like to know the more complicated way, because I compare two tables which contain different entries.
Would anybody be so nice and help me?

Check:

Need help with nested loop (c:forEach) tags. Can I break from inner loop?

Hi all, I have this annoying problem and I am looking for any suggestions.
I have 2 select boxes. One is for all available users, and second - for selected users (designated as admins). The list of all users is available in a collection (2 properties userId and userName displayed in the code below). The list of admins contains only userId (as strings).
I have no problem with populating selected users (admins) list, reusing pretty much the same logic below, but I cannot find a way to break out from the nested loop once the match is found, to avoid repetitions leading to incorrect display of results.
<select name=available>
<c:forEach items="${users}" var="user" varStatus="outer">
    <c:forEach items="${adminIds}" var="adminId" varStatus="inner">
        <c:if test="${user.userId!=adminId">
             <option value="<c:out value="${user.userId}" />"><c:out value="${user.userFullName}"/></option>
        </c:if>
    </c:forEach>
</c:forEach>
</select>
<select name=selected>
<c:forEach items="${users}" var="user" varStatus="outer">
    <c:forEach items="${adminIds}" var="adminId" varStatus="inner">
        <c:if test="${user.userId==adminId">
             <option value="<c:out value="${user.userId}" />"><c:out value="${user.userFullName}"/></option>
        </c:if>
    </c:forEach>
</c:forEach>
</select>Can anyone help, please? I am also restricted to JSP 1.2

How Can we stop the execution of java program which contain infinite loop

Dear All,
I create one .bat file which which execute the simple java program
I write one java program which execute above .bat file using instance of Runtime Class of java
It's work fine if java program which is executed by .bat file is simple(Which has normal termination)
But if that program contain inifinte loop then that file will goes on executing untill I close it manually
So i want a solution in java which close that bat file (command window ) which is in running condtion
If there any solution please replay me
I try to close that .bat file using destroy() ,stop() method of Process and Runtime , Thread Class
but it did not give me correct output
.bat file still running !!!!!!!!!
Thanks in advance

Why not use javaw.exe to make the app run so you don't need the dos window (which is presumably what you are actually talking about when you say bat file).

How do I place an image in a div container for only 1 page?

I am designing a web site for my wife using DW. The basic
look of all the pages follow this format: <darhosta.com>. I
need to make about four pages that look different that the basic
look above. In essence I want to make the background white and have
a 'background image in the div container. Thanks to Nancy, who
frequents these forums, I was able to get rid of the background
image that surrounds the main div container with the CSS she
suggested. (Here's the page with Nancy's suggestion of the correct
CSS and where to insert it -Thanks Nancy-: <
http://darhosta.com/Pages/iltn.html>
The page is almost done but I want to have a background image
in the main div container. I've been trying to figure this out on
my own but haven't been able to. Can anyone help me? Thanks for the
help,
Lou
Note: Here the CSS that Nancy suggestion with my modification
included to get rid of the background. If anyone needs to see more
of the code please email me.
Thanks again,
<style type="text/css">
body {
background-image: none;

I now want to place an image in the div container. I've not
been able to figure out how to do this.

No need. All source is available from the link.
In ilth.html, change this:
<style type="text/css">
body {
background-image: none;

</style>
<link href="../css/global.css" rel="stylesheet"
type="text/css" />
<script src="../SpryAssets/SpryMenuBar.js"
type="text/javascript"></script>
<link href="../SpryAssets/SpryMenuBarHorizontal.css"
rel="stylesheet" type="text/css" />
to this:
<link href="../css/global.css" rel="stylesheet"
type="text/css" />
<script src="../SpryAssets/SpryMenuBar.js"
type="text/javascript"></script>
<link href="../SpryAssets/SpryMenuBarHorizontal.css"
rel="stylesheet" type="text/css" />
<style type="text/css">
body {
background-image: none;
background-color: #fff;
#container {
background-image: url(../images/global/bkPage.jpg);
</style>
By embedding the styles AFTER the linked stylesheets, the
rules
will overwrite property/value pairs in identical rules that
may already exist in the linked sheets - assuming no

GR is not posible in an inbound delivery that contains nested HU

Hi!!!
I need your halep!!!
I have the next problem in a cross company process:.
When the outbound delivery ( that contains nested HU), the good issue is posted, an inbound delivery is created (using a standard workfolw that is used to transfer the outbound delivery HUs in the inbound delivery).
The problem is, that I can't to post good receipt for the inbound delivery that contains the nested HU (provided from the outbound delivery).
The system show the next message error:
"Post Goods Receipt" is not allowed (HU 362784)
Message no. BS007
Please, coulyou help me?
Thanks a lot!

Problem with Nested loop in Fox-Formula

Dear Experts,
Let s share the scenario :
MaterialGroups with following Keys for Example AAAA, BBBB, CCCC..., Materialgroups are selected in the 1st input ready query, which is assigned to DataProvider DP_1 in a webtemplate.
every Materialgroup has several Materials, for instance:
Materialgroup AAAA has following Materials: AAAA10, AAAA11, AAAA12, AAAA13...
Materials are selected in a second input ready Query, which is assigned to a second DataProvider DP_2 in the Same Webtemplate as the query 1.
Both Materialgroup and Material are based on the same Aggreagtion level and same real time cube.
I want to copy the input values for every MaterialGroup ( 1st query, DP_1) only to it s own Materials (2cond Query, DP_2).
To resolve this Issue i wrote the following Fox Formula code with a nested loop, however it does not work properly. when I m debugging the code, i could release that the second Loop was ignored.but wehn i replace the second loop (nested loop) with a fixed value it s seems to work properly
DATA MG1 TYPE MATG.<------ MaterialGroup
DATA MT1 TYPE MAT.<----
Material
DATA S1 TYPE STRING.
DATA S2 TYPE STRING.
DATA S3 TYPE STRING
DATA K TYPE F.
DATA Z TYPE F.
FOREACH MG1.
To check Materialgroup in debugger
S1= MG1.
BREAK-POINT.
K = {KEYfIG, #, MG1}.
BREAK-POINT.
FOREACH MT1. <----- if i set MT1 to a fixed value like AAAA11 then S3 get the wished value namely AAAA
S2 = MT1.
BREAK-POINT.
S3 = SUBSTR (MT1, 0, 4).
BREAK-POINT.
IF S1 = S3.
{KEYFIG, MT1, #} = K.
following Statement is only used To check in debugger if Material has become the same Materialgroup value
Z = {KEYFIG, MT1, #}.
BREAK-POINT.
ENDIF.
ENDFOR.
ENDFOR.

XML nested Loop?

hi all.
I´ve just completed a little test for making a tree
component with custom
icons / bransch.
However, i can only get my first branch to show custom
icons.(links -
document) I figure I need to make a nested loop to Iterate
over
nextSibling?. I tried ALOT, but i guess I´m doing
something completely
wrong.
here is code for my tree so far:
my_xml = new XML();
my_xml.ignoreWhite = true;
my_xml.load("tree.xml");
my_xml.onLoad = function(){
myTree.dataProvider = this.firstChild;
var folders = my_xml.firstChild.firstChild;
var docs = folders.childNodes;
for (var i=0; i < docs.length; i++){
currDoc = docs
trace(docs);
var docIcon = currDoc.attributes.pic;
switch(docIcon){
case "pdf":
myTree.setIcon(currDoc, "pdfIcon");
break;
case "word":
myTree.setIcon(currDoc, "wordIcon");
break;
case "excel":
myTree.setIcon(currDoc, "excelIcon");
break;
case "ie":
myTree.setIcon(currDoc, "ieIcon");
break;
}//switch
} //for
};//onLoad
And here is the XML I used:
<node label="» Dokument typer">
<node label="» links - document">
<node label="test.url" url="
http://www." pic="ie" info="test text" />
<node label="test.doc" url="test.doc" pic="word"

<node label="test URL" url="

Solved it ..works nicely :D
